Google may take its battle for global domination to the high seas with the launch of its own “computer navy”.
The company is considering deploying the supercomputers necessary to operate its internet search engines on barges anchored up to seven miles (11km) offshore.
The “water-based data centres” would use wave energy to power and cool their computers, reducing Google’s costs. Their offshore status would also mean the company would no longer have to pay property taxes on its data centres, which are sited across the world, including in Britain.
....The supercomputers housed in the data centres, which can be the size of football pitches, use massive amounts of electricity to ensure they do not overheat. As a result the internet is not very green.

Furthermore, using the signal generator, we were also able to set the DC bias voltage and tune the output voltage to get maximum voltage out. There is a wide variety of SMPS topologies and their practical implementations used by PSU manufacturers. The supply powers a 27 inch lcd tv display. Ironically, now that PG&E is offering to disable the wireless RF function (for a hefty price) in their smart meters, we find that there's an another extremely critical problem with the meters. The results are attached here. Therefore, if the voltage levels at any of these points are abnormal, it is definitely indicative of an underlying problem. CURRENT indicates the flow of energy from the battery and is measured in AMPERES (or AMPS). Power output is an important metric for your home or commercial solar panel system. Calculate • ON & OFF time intervals. I’ve got a 130 watt power supply, left over from my last Dell laptop, that I would like to use on my new Ultra book which came with a 65 watt power supply. If the timing is adjusted too far advanced or retarded (in front or behind the timing marks) the engine will have low power output. While a mica’s or a Type DPP’s capacitance is nearly independent of voltage and temperature, by comparison, a high-K ceramic dielectric like Y5V can lose ¼ of its capacitance from room temperature to. For this example we will use V IN = 8V. Figure 2 the full circuit diagram of 0-45V 8A switching power supply. These large transformers. CMOS input stage thresholds vary and are equal to two-thirds of Vcc and one-third of Vcc. Switch Mode Power Supplies" (271 pages), please visit: Http://www. Since a transformer is used, multiple outputs are possible. Usually output impedances should be low, less than a tenth of the load impedance connected to the output. How to repair a switching "switch mode" power supply. Also a brief explanation about the difference between Linear and switch mode power supplies. Switching Power Features & Benefits What are switching power supplies? Switching power supplies, sometimes referred to as SMPS power supplies, switchers, or switch mode power supplies, regulate the output voltage using a complex high frequency switching technique that employs pulse width modulation and feedback. A boost converter (step-up converter) is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load). Low heat generation in SMPS. It has high output voltage ripple. Nov 20, 2017- Discover how to repair SMPS power supply using a super crazy detailed tutorial manual for troubleshooting all sorts of SMPS problems. (3) In order to inspect the negative output, the probe of your ohm meter must be set in reverse. SMPS or switched mode power supply is an electronics device that is used to convert AC to DC, AC to AC, DC to DC and DC to AC voltages. No TX output in all modes.

Low-Voltage Repair T he low-voltage section of the power supply is a. Understanding The Functions Of Switch Mode Power Supply Troubleshooting linear power supply is extremely straightforward as opposed to SMPS or switch mode power supplies. I have replace the smd diode S1WB S60. transformer first steps down high voltage AC to low voltage AC. It has Hi-End R-Core transformer and support multi-rail output such as 19V,12V,5V, and adjustable output from 5V-19V. This is usual done with a opto coupler that turns on when the voltage is high enough. Most switching power supplies regulate their output using the method called Pulse – Width Modulation (PWM). Musical Laboratory*'s Paeonia Rev. 400V is probably on the edge. To keep the output voltage stable the switcher must know if the voltage is too high or low and adjust its output accordingly. Then power up and recheck the output side. High CV density is preferred in the input filter caps to reduce board space, although it is more critical for the output filter caps. The DAQ as a part of hardware convert the value to the digital then send the data to the pc to be analyze and stored in the memory. A voltage to current (V-I) converter accepts as an input a voltage Vin and gives an output current of a certain value. Your TV can still work if the voltage is low. The output impedance of the LM317, even at DC, depends strongly on the load current, with impedance dropping with increasing load. The aim of this was to hack, bodge and generally modify an AT type PC PSU (Power Supply Unit) to give a higher output voltage than originally intended by the original design. Low Voltage Transformers for Landscape Lighting. A typical current output is 4 to 20 mA in a 2 wire configuration, but there are 3 wire configurations which can provide 0 to 20mA or 4 to 20mA current loop output signal with a separate positive supply and output connection. Figure 2 the full circuit diagram of 0-45V 8A switching power supply. 7 V, the output remains relatively constant (Region I). 2 shows the transfer curve for TTL inverter without any fanout. Consumer Durable, IT and Mobile Accessories, Smartphones, TVs, Refrigerators: Intex. An SMPS is a Device to efficiently provide a regulated output voltage, from different level of the input voltage. Troubleshooting: AC Power adapter LED is off when you plug the adapter into the wall but not into the computer. Buck Converter Design Example d. The Behringer A500 may please DJs and musicians who use concert speakers that require high output power. A feedback circuit is used to control the output voltage by comparing it with the reference voltage. This is achieved by feeding back a certain percentage of the output voltage to an earlier point in the circuit, the phase inverter. If the output voltage is lower than 10 volts, then the Schottky diodes are used as a rectifier. low loads Q101 is turned on with a Vds well below the half bridge input voltage. The LM317 lowest voltage is 1. When you have checked all the possible causes listed and you are still experiencing the problem, see your John Deere distributor. A typical SMPS can be simplified as shown in the block diagram of Figure 1. The output voltage tends to have a ripple component at the frequency of the transformer waveform. SMPS are home appliances and metering. 0 Volts when the output is commanded on, the DTC will set. In normal operation, the HIC provides high efficiency and low EMI noise with bottom-skip quasi-resonant operation during light output loads. TEA19361T GreenChip SMPS control IC Rev. This should.

Analysis of a floating vs. A buddy told me that it might be because of the PSU and my PSU might be broken, so i decided to run a test and check the voltage rails. Switcher for Low Standby-Power Offline SMPS The NCP101X series integrates a fixed−frequency current−mode controller and a 700 V MOSFET. It transfers power from a DC or AC source to DC loads, such as a personal computer, while converting voltage and current characteristics. If not, the. Next, send the low voltage AC through a rectifier to make it DC and use a capacitor to smooth out the ripples in the DC. If the voltage measured in step one is outside the range, check the voltage across the alternator output terminals. Regarding the "high-speed" and "low-speed" stator arrangement often mentioned on Mercury motors, my understanding is that there are two coil windings. It uses two sealed switch-mode power supply modules to provide ±24 V. Put the belt back on and re-test for generator voltage with DF grounded. output voltage with load current. By the way you can’t test an ATX power supply without load otherwise it may turned On for a while and then shut down. When designing an SMPS, please check which. 2 Mechanical System Not Responding. However, using the switching power semiconductor in the SMPS system, the problem of the switching loss and EMI/RFI noises have been closed up. With off-load power draws as low as 0.

When the circuit C voltage is pulled low by the ECM: the charging voltage at the battery will range from 12. No adequate discussion of this problem can be undertaken without reference to basic control theory of. However, Q2 MOSFET is working normally and its. As both outputs are wired to the same terminals on the pcb, both should show the same voltage (apart from a few mV difference coming from voltage drop due to output currrent and wire resistance). If there is no power or the voltage reading is low disconnect the output wires with the power off. power supply output voltages were still high. Microsoft's Surface Book 2 has a power problem that causes it to drain the battery even when plugged in, when playing 3D games on certain settings, PCWorld has confirmed. Its basic function is to deliver stabilized low-voltage DC to the digital logic circuit it feeds. The difference in the input and output voltage is by the way called as dropout voltage. Ratcheting that up a notch, many Class D amplifiers are used in conjunction with switch mode power supplies (SMPS). But before we face that possibility, we first need to find the extent of the low-voltage damage. For a PC power supply, a couple of amps may be needed - a 2 or 3 ohm 15 W resistor on the +5 output. Switched-Mode Power Supply: A switched-mode power supply (SMPS) is an electronic circuit that converts power using switching devices that are turned on and off at high frequencies, and storage components such as inductors or capacitors to supply power when the switching device is in its non-conduction state. The CoolGaN 600 V industrial-grade device (IGLD60R190D1) enables performance and cost optimization for low- and mid-power applications, such as in the area of low-power SMPS and telecom. And in the compressed air system, the pressure switch will turn on the compressor when system pressure gets low. i dint find any output voltage written der. SMPS is the Switched Mode Power Supply circuit which is designed for obtaining the regulated DC output voltage from an unregulated DC or AC voltage. 31 Amps, or 3,310. In that case, the output voltage would rise without limit till any of the converter components gets damaged. Engine Brake Output No. Recommendations Although the LM7809 voltage regulator performed the step-down converter circuit quite well, there is a potential problem that might occur in the long run. The nominal ambient temperature for the Universal range of Phaseo power supplies is 50°C. Acquiring an ideal, long life switch mode power supply circuit design may appear quite illusive, however an outstanding IC the FAN7602B from FAIRCHILD promises excellent features and specially suitable for SMPS circuit applications providing fail proof and efficient results. Why the Capacitor in Your Power Supply Filter is Too Big 3 years ago by David Williams The job of the capacitor in the output filter of a DC power supply is to maintain a constant DC value by removing as much power ripple as possible. In other words, there is a voltage gain reduction of 6dB, or a factor of two, in the stages enclosed by the feedback loop. There are basically two categories of Power Supplies: Linear Regulated Power Supply and Switching Mode Power Supply (SMPS). Depending on the output power, switched mode power supplies (SMPS) operate in the frequency range from about 10 kHz up to the MHz range. I don't have a lot experience with this type of power supplies so I can't figure out what is causing this problem. Why? SW1 delivers pulses of current to the output by being in one of two states - fully ON or fully OFF. This ripple is due to incomplete suppression of the alternating waveform within the power supply. In the former case, The SMPS was fed with DC 24V - no bias winding was necessary. Because this occurs at typically 1/4 of the maximum peak value, no acoustic noise takes place. This should. The output of this transformer is then rectified & smoothed by using the output rectifier & filter. Output impedance as function of load current: 1mA (red), 10mA (green), 100mA (blue). I've followed all the instructions, but the output voltage on the +12 V side is still low -- what can I do?? Many of the R/C folks are converting power supplies for the purpose of driving field chargers and are finding that voltage levels below 12 volts are sometimes insufficient to power their chargers. When it is unplugged from the computer but still plugged in to the wall, it is normal to find that the voltage may be 1 to 3 volts higher than the printed output rating. 12v to 230v Inverter Circuit Schematic using Pulse Width Modulator IC SG3525 Khaleel / January 2, 2014 So far we have published so many inverter circuits here at circuitsgallery and now I think it’s time for me to introduce another one that has more inverter efficiency.

These boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2. In comparison to other capacitors used for SMPS filtering, multilayer ceramic capacitors offer better ESL. 1 Current Below Normal Or Open Circuit. Nevertheless outweigh the benefits, because primary switch mode power supplies are superior to the transformer power supplies technically far. Re: SMPS in series connection 05/10/2009 10:50 AM It is remarkably simple to build a Switched mode PS with modern chips, I recently built a 10 amp programmable (for voltage output) power supply of this type designed by and published by the Elektor Magazine. The upper diode thus can be selected for half current than the bottom one. 1 Discrete Low Voltage SMPS Switch mode power supplies built using discrete components are an essential subsystem of modern commercial electronics. 5A, our result is 6. By producing a reliable current to a device, DC power supplies generate and/or simulate a steady flow of voltage to loads in a circuit. Low heat generation in SMPS. i dint find any output voltage written der. Fly back Converter type SMPS Working Principle. The EMG-85 has more low end and less high end then the EMG-81. Numerically, it’s the output noise at a given gain setting minus the gain. by Miguel Usach Merino Download PDF The capability to finely adjust the output voltage in a power supply makes it is possible to remove tolerances and drops in the power path, verify the operation at the system limits, or implement simple dynamic voltage control for microprocessors. Microsoft's Surface Book 2 has a power problem that causes it to drain the battery even when plugged in, when playing 3D games on certain settings, PCWorld has confirmed. If the output voltage is above 15. The results are attached here. This voltage should also be variable over as wide a range as practical. hm's law (E=IxR) tells us that even very low resistance in the starter circuit will cause the starter to turn slowly, because of low voltage. Apple joined USB-C with USB 3. The power supply is delivering constant power into the load, and doing a very good job of it. 1 on its 12-inch MacBook and new MacBook Pros. e, A, B, and the complement of C ). Depending on the output power, switched mode power supplies (SMPS) operate in the frequency range from about 10 kHz up to the MHz range. Why SMPS often fail after just a few years of service. If the alternator fails completely, and the output voltage goes to zero, the lamp will be lit at full brilliance. This page explains the principals of operation of a switching mode power supply and reviews its main parts and functions. Almost all of the low voltage output capacitors were domed and leaking. I bought this unit to replace a Malibu unit that failed one month after the one-. SMPS Basics The Buck Converter. A typical current output is 4 to 20 mA in a 2 wire configuration, but there are 3 wire configurations which can provide 0 to 20mA or 4 to 20mA current loop output signal with a separate positive supply and output connection. The input rotates at 2000 rev/min clockwise. The light bulb trick. The voltage was right, but would drop immediately with load, and clicking noises could be heard from transformer. the parameter extraction and dynamic auto-tuning of low power digitally controlled dc-dc switch-mode power supplies (SMPS). By their very design requirements to pass EMI SMPS's rarely conduct EMI/RFI across the power supply, most linear supplies may as well be transparent to anything above a few 100Hz. – Since the phases of a high-voltage overhead transmission line must be spaced further apart to ensure proper insulation, a high-voltage line will have a lower capacitance than a low-voltage line. Barrancos Mooney Operatoria Dental Descargar Pdf on this page. Wilkinson power dividers are limited in their low frequency range (f LOW) to a few hundred MHz while resistive power dividers reach to DC. The output voltage of the power supply is regulated by feeding some of the output back to the integrated circuit that controls the switching transistors. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 90%. According to image; I don't measure C1 capacitor voltage, it is zero. To have a zero voltage on the output I've put 3 diodes D7,D8 and D9 on the output of the LM317 to the base of the 2N3055 transistors. 01 ohms resistance in the starter cable will cause a 2 volt drop in voltage at the starter; 0. But I would not count on that. TEA19361T GreenChip SMPS control IC Rev. As the input voltage is increased from 0 to 0. The output voltage tends to have a ripple component at the frequency of the transformer waveform. These supplies do not generate EMI. The second error amplifier is blocked by the voltage of the pin 15 of IC1. s) Most problems with equipment using switch mode power supply (s. 2 Voltage Low. This application note describes a low power SMPS with. Switch mode power supplies (SMPSs) are used in a range of applications as an efficient and effective source of power.

Be warned: even though this small circuit can be operated on batteries/low voltage wall-worts, the output is more than enough to kill you!. To keep the output voltage stable the switcher must know if the voltage is too high or low and adjust its output accordingly. No matter what the troubles can be, I'm going to work with a typical technique strategy to check that. as having its controller and internal power FET. Reply to Thread. My new house has some power problem it always low voltage. Poor efficiency and wasted energy. When there is a local regulator, the design is simpler and sometimes the power supply filter can be reduced. For the operation basics of SMPS PSU see our power supply tutorial. When the output voltage decreases, the voltage on the error amplifier then increases. 7 and a traditional SMPS is much worse: sometimes as low as 0. The input rotates at 2000 rev/min clockwise. Single Supply Op Amps. control from the PCM to the TIPM. Even though the external load resistance is varied, almost no change is seen in the load voltage. The output of the ETD39-based transformer is rectified with schottky rectifier STPS3045 and an LC filter is used to filter to pure DC. The LM317 lowest voltage is 1. There are 807 power amp smps suppliers, mainly located in Asia. Originally it had 5v standby power only and would not turn on. If the voltage is over 13. If the filter capacitor is rated as 1000uF 25 VOLT then you can expect the output voltage somewhere from 14 to 18 volts. S MPS transfers power from a source like the electrical power grid to a load (Eg: Computer). The increasing requirements of lighter, smaller and more efficient electronic products require power supply designers to develop AC-DC and DC-DC converters with high power density and efficiency. The value of D, which is the ratio of the square wave's on. Most power supplies also have a voltage selector switch that lets it work with 110V or 220V power sources. 155356 today i built this flyback smps transformer for this circuit as shown above using PQ3230 core with Nprim = 24T (swg 26 x 4) , Nsec = 4T(swg 23 x 4) & Naux = 5T(swg 26 x 1). 12v to 230v Inverter Circuit Schematic using Pulse Width Modulator IC SG3525 Khaleel / January 2, 2014 So far we have published so many inverter circuits here at circuitsgallery and now I think it’s time for me to introduce another one that has more inverter efficiency. My Electronics Course on Patreon, Link Here: h. This is because, without load the output voltages produced will become very high and this will trigger the protection circuit to shut down the power. If the output voltage from the stationary armature coils drops due to an increase in demand, more current is fed into the rotating field coils through the voltage regulator (VR). PNP Output: Transistor output that switches the positive voltage to the load. An Oxygen sensor is a chemical generator. Our observation is smps which are going in thermal shutdown that have flickering problem. The LM7809 voltage regulator was also able to stabilize the resulting DC output voltage, as it was determined to have reasonably steady value. Many low power or low cost DC/DC converters are unregulated circuits. If this reading is less than 100K ohms, the transformer is bad. Unusual heat output can be an early sign of problems ahead. So I had same problem but I didn't realise this and changed RAM Processor and MB. Until this signal is sent, motherboard will refuse to start up the computer. A voltage to current (V-I) converter accepts as an input a voltage Vin and gives an output current of a certain value. Learn about the normal output rate, how it's measured, and causes of low cardiac output. 12W 12V SMPS Demo Board with ICE2QR4780G AN-DEMO-2QR4780G About this document Scope and purpose This document is an engineering report that describes universal input 12 W 12 V off-line flyback converter using Infineon Quasi-Resonant CoolSET™ ICE2QR4780G which offers high efficiency, very low standby power, wider V VCC. Hi Sir,I have repair 2 sets of Sony VCR with SMPS problem. back to power supplies. TEA19361T GreenChip SMPS control IC Rev. This reference voltage is what tells the ECU to increase or decrease the field strength in the alternator. 5 volts for 12 volt battery systems. One of the simplest tests you can perform on a power supply is to measure the output voltages. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 95%. or oscillation of their power supplies if the ESR of the output filter capacitor is too low. Linear topology would be unusable for this power (2400W = 2. So my power hungry smartphone’s charger has an output of 5V @ 1. SMPS power supply problems are generally classified into no power, reduced output power, higher output voltage, power supply cut-off just after occasionally or as soon as turn on, power blink. Low output impedance; So the first on our list is power factor – and before I get into this tough subject let me add that a classic power supply has a power factor of about 0. 11/30/2010 09:39:45 UPS: The battery power is too low to continue to support the load; the UPS will shut down if input power does not return to normal soon. below a given value, e. The SMPS modulates the low frequency noise to higher frequencies where it can be dealt with effectively. Its basic function is to deliver stabilized low-voltage DC to the digital logic circuit it feeds. My Problem is no output voltage. Example: DC Amperage - Now we know that our application uses 36 watts of total power. I've shared a lot of SMPS power supply projects with IR2153, especially AT, ATX power supply. Chopper is a basically static power electronics device which converts fixed DC voltage/power to variable DC voltage or power. In order to control the output voltage a feedback circuit is used by comparing it with the reference voltage. Shop with ease and confidence at the USA's largest 100% power supply focused distributor. Live data and 24/7 monitoring for your critical assets. If the power supply and load requirements are closely matched, there is usually not a problem. DC Voltage - Output Voltage is rating of your battery system, usually a single 12 volt battery. Usually, a transformer fails only after another part in the electrical circuit shorts to ground or draws an unusually high amperage. 8 volts to the ECU. I still want to reduce it to the minimum possible. 5 Amp 600 Watt : Power Supplies & Wall Adapters Toggle navigation Jameco Electronics. Familiarization of components is critical because it allows you to solve common SMSP problems like zero power, voltage output that is either too low or too high, and of course…total power shutdown. Hong Ma Sept. motherboard problem, other wise change smps then turn on computer if it is boot-up smps problem. I'm using a SMPS of ±12v, 150W for my application. 1 seconds) or flicker by providing a starting voltage that is sufficiently high to start a discharge through the lamps without the need for heating lamp electrodes. When the engine is cold, the O2 sensor should output 0. Usually, these types of transformers transform 110 volts of current into a safer 12 volt current to allow low-voltage lighting in landscapes or gardens outside homes. Since 555 Timer is used, the output may slightly vary around the required duty cycle of 50%, i. The DTM medical external power supplies are housed in a rugged plastic case and are rated from 40 to 300W with output voltages from 5V to 54V. voltage low: The auxiliary 5 volt supply output voltage is low. An SMPS is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage. This should. this, as well as other power line noises as well tend to make the DC a bit 'dirty'. Because these capacitors have a DC value, they are actually storing a lot of energy that never gets used. delta-conversion on-line. 3 V output voltage regulator outputs only 3. For the operation basics of SMPS PSU see our power supply tutorial. This is often unnoticeable until failure occurs. Another characteristic of many Push-pull amplifier is the high global feedback used to get a good damping factor because to increase the output power often are used output transformers with low turn ratio. Low or no voltage to the primary (positive) side of the coil 3. It's often necessary to power a low voltage circuit such as a microcontroller with HV AC line current. Musical Laboratory*'s Paeonia Rev. If the input and output voltages are 90 degrees out of phase then everything everyone learned about transformers is totally wrong. We need to determine the nominal input voltage and it must be a few volts greater than V Z. ECU Controlled Variable Voltage Alternators. An SMPS usually has mV of output ripple even with very low ESR capacitors. SMPS Basics The Buck Converter. e TOP switch IC derating. effect of reflected wave voltage is generally not a problem if the power run is less than 15 feet (5 meters). Or is the standard protocol in this case to drop dead without trying to avoid this problem? From my experience with my desktop and a few hard drives and a low power 350W PSU, it would instantly shut down if 5 hard drives were all trying to spin up at the same time. CIRCUIT BUCK_BASIC. Derating or using a low temperature rise generator is a means of compensating for increased heat losses and possibilities of reduced power factor. What we want to do is to change the voltage divider, changing the voltage at which the comparator tells the control circuit to charge the capacitor. Voltage and Current in Power Transformers. The PWM circuit regulates the DC output voltage by adjusting the ON/OFF durations of switching transistor Q. the parameter extraction and dynamic auto-tuning of low power digitally controlled dc-dc switch-mode power supplies (SMPS). Ribbon microphones are good for quality studio recording of acoustic instruments though can be delicate, for instance you wouldn’t want to put one in front of a bass cabinet. Coupler A key difference between couplers and power dividers is that couplers create a phase shift between the output signals. n If all inputs are low, the transistor cuts off and V OUT goes high. DC Power Packs. It transfers power from a DC or AC source to DC loads, such as a personal computer, while converting voltage and current characteristics. Figure 4: Example of Constant Current SMPS Another advantage of using a switching power supply is the ability to boost the output voltage. 5 volts of the power supply (and this can be as much as 3 volts). Two rules will let you figure out what most simple op-amp circuits do: 1. It will provide three isolated channels: 2 * 0V. This article describes how to build and test one from both new. Switching power supplies have high. Therefore, the inputs to this logic gate should be A, B, and C’ (i. In that case, the output voltage would rise without limit till any of the converter components gets damaged. output, though delivering the same average voltage to a load, is not appropriate to delicate electronic devices which rely on precise timing. V IL: [Voltage Input Low] The maximum positive voltage applied to the input which will be accepted by the device as a logic low. Another option may be a low input capacitance passive probe such as the TPP0502, which is the only low attenuation, high bandwidth, and high impedance passive probe in the industry that is suited to make low voltage measurements on signals with high frequency content. Transformer for Low Voltage going to Ring Pro Hi, I attempted an installation of the Ring Pro but found that it was not powering on after everything was connected. Another insidious problem related to the old style power supplies is that magnetic components are very inefficient at low frequencies. Is there any chance that my PSU isnt broken and OCCT is displaying wrong. Above this temperature, derating is necessary up to a maximum temperature of 60°C. MAX17000 Complete DDR2 and DDR3 Memory Power-Management Solution 2 Maxim Integrated ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (VIN = 12V, VCC = VDD = VSHDN = VREFIN = 5V, VCSL = 1. The output voltage of the power supply is regulated by feeding some of the output back to the integrated circuit that controls the switching transistors. No adequate discussion of this problem can be undertaken without reference to basic control theory of. CMOS input stage thresholds vary and are equal to two-thirds of Vcc and one-third of Vcc. Use of output voltages of SMPS •Power Good Signal :- • To prevent the computer from starting up prematurely, the power supply puts out a signal to the motherboard called 'PWR OK' after it completes its internal tests and determine that the power is ready for use. So there is little EMI problem. VOLT ® low voltage landscape lighting transformers are the best on the market. To efficiently charge a battery, we can use constant current constant voltage SMPS. In the above example 1 amp flows through ammeter 2. Whereas a linear load produces a sine wave current, the SMPS draws current pulses at only one portion of the applied voltage waveform. The voltage across these terminals should be between 0 and 0. Nowadays, there is already low dropout voltage linear regulator in the market. • The use of smaller transformers and smoothing capacitors makes switched mode power supplies lighter and less bulky. 1 Current Below Normal Or Open Circuit. The SMPS also provides most of the low voltages that were produced by the scan-derived supplies. An overvoltage condition is a condition that causes the power supply output voltage to exceed its setting. 1 on its 12-inch MacBook and new MacBook Pros. SMPS is the Switched Mode Power Supply circuit which is designed for obtaining the regulated DC output voltage from an unregulated DC or AC voltage. See more ideas about Switched mode power supply, Repair manuals and Manual. If your amp’s gain was 10 and the full-scale signal to the headphones was 0. I am an instructor that teach electronic repair subject and also I have written 3 e-books in the electronic repairing topics. Forget the SMPS and use a standard linear power supply. It is constantly making a comparison between the Oxygen inside the exhaust manifold and air outside the engine.

Turn ANY guitar into a polyphonic guitar-synthesizer or record tablature by playing it.
###### A demonstration video is available at: jamorigin.com/mg #####
MIDI Guitar is the world’s first app to transcribe guitar playing into MIDI. The transcription runs in real-time, with latency and accuracy comparable to expensive and inconvenient hardware MIDI guitar solutions.
MIDI guitar is 6 years under development(!) and based upon new patent-pending polyphonic pitch detection and –prediction technology that can accurately recognize polyphonic signals, such as complex chords or finger-playing with very low latency and without spurious hits.
MIDI Guitar use WIFI-MIDI to communicate with digital audio workstations in a frictionless setup, Virtual MIDI to drive other iOS synth apps using Apple’s virtual MIDI standard, Cable-based MIDI to control hardware synths or connect to DAWs with lowest possible latency.
In order to use MIDI Guitar you need a iPhone 4s, iPad 2, iPod5 or later. Using older devices may work for some purposes. You also need a guitar interface for best results. We recommend the iRig, but other interfaces should work as well. Using an acoustic guitar with the built in microphone might work for some purposes but is not optimal.
Virtual, Cable and WIFI MIDI can be evaluated in the free version, with interruptions. Full version is without interruptions.
MIDI Guitar Support
What's New in Version 2.0- MAJOR tracking and latency improvements! Now runs the same engine as the renowned MIDI Guitar VST/AU version.
I was trawling through some old apps and came across this one. It's been 2 years since the last update but it works like a charm. When I first tried it I was using a basic analog Guitar Input (iRig) to my iPad which plugged into the headphone/line input jack. Unfortunately using a single jack for input and output doesn't work very well and feedback is a common problem ... and it understandably drove MIDI Guitar insane!
I now have the Apogee One for iPad which is a vast improvement, but I'd never tried MIDI Guitar with it. So I downloaded the fully functional free app and plugged in. Wow! This is really is as good as any of the Guitar to MIDI converters ( basically pitch detectors ) I've tried. Even the expensive ones. Moreover it performs incredibly well in a polyphonic mode without a fancy pickup needing to be installed in your instrument.
The app has a built in test Piano sound to confirm things are working and I was able to play some very nice chords and arpeggios. But the fun begins when the MIDI output gets switched to the input of a decent synth sound source. I used Thumbjam which has a very robust MIDI implementation and plenty of sounds to choose from. But there's plenty of others ... Hmmm... Perhaps I'll try a few and post about them? Anyway, Thumbjam was great fun and it's a real blast to hear non-guitar tones in response your strumming and plucking.
The Free version does cut out after a while to prompt the purchase of the $19.99 full version. But if it grabs you, the purchase is worth it ... Or at least keeping an eye out for a sale.
In terms of improvements it would be nice to define a MIDI channel output ( 1-16), but that's my only gripe!

February 2012 Compact Imaging Reaches Agreement on Research Collaboration with Irish Universities
Compact Imaging Reaches Agreement on Research Collaboration with Irish Universities
Compact Imaging (CI) today announced an innovative research collaboration with National University of Ireland Galway and University of Limerick.
The two-year agreement, in the scientific field of biophotonics, specifically optical coherence tomography (OCT), will explore and further develop CI’s novel technologies. OCT is an imaging technique similar to ultrasound, but employing light rather than sound.
The project will combine National University of Ireland Galway’s globally-recognised body of OCT research in medical and biological imaging with CI’s development and intellectual property in the area of multiple-reference OCT. The focus will be on Compact Imaging’s MRO™, multiple-reference OCT, architecture.
CI is an early stage technology company focused on the rapidly expanding market for non-invasive optical imaging, measurement and analysis. The Company’s MRO™ technology makes possible very small (cell phone size), low-cost, robust OCT-based devices for these applications. CI, based in Silicon Valley, holds a portfolio of US patents covering multiple-reference optical coherence tomography (MRO™).
The collaboration makes the extensive scientific research capabilities of National University of Ireland Galway (NUI Galway) and University of Limerick (UL) available to CI. The agreement has been led by and supported by Galway University Foundation and University of Limerick Foundation. The agreement will lead to the University foundations receiving equity in CI. Additional financial details are confidential, for commercial reasons.
NUI Galway’s Professor Martin Leahy will direct the research efforts. Professor Leahy is Chair of Applied Physics at NUI Galway, Scientific Director of the National Biophotonics Imaging Platform Ireland (NBIPI) www.nbipireland.ie and Director of the University’s Tissue Optics and Microcirculation Imaging Laboratory (TOMI) http://tomi.nuigalway.ie.
“Physics has delivered extraordinary advances in almost every facet of modern life,” said Professor Leahy. “From the humble thermometer and stethoscope to X-Ray, CT, MRI, ultrasound, PET and radiotherapy, our health has been transformed by these advances. Photonics promises to bring healthcare to the next level, as it is the only means to see cells and molecules in small, accessible, low cost and safe imaging systems.
“Compact Imaging’s multiple-reference OCT technology has the potential to harness all these advantages, delivering solutions to health and security markets with a distinct edge,” added Professor Leahy.
“Our proprietary MRO™ technology has a broad set of biological imaging and measurement applications in fields from medical to security,” said Don Bogue, CEO of CI. “By embarking on this collaboration with Professor Leahy and the laboratories at National University of Ireland Galway, Compact Imaging gains access to outstanding research capability with a group that has the right scientific expertise and research focus to move MRO™ well beyond where our startup-level resources would otherwise allow. We expect that this collaboration will accelerate our development and delivery of small low-cost solutions to a variety of markets,” he said.
The underlying imaging technology, optical coherence tomography (OCT), was first commercialised more than a decade ago for use in ophthalmic and medical diagnostic imaging. CI’s MRO™ is a very different architecture from that used in conventional OCT systems. The architecture enables design of small form factor (cell phone size), low cost devices ideally-suited both to integration with large multi-purpose instruments for office or clinic use and to higher volume mobile or remote applications.
“Leveraging knowledge to support innovation is an important part of the mission of universities. For NUI Galway and UL to partner in this way with an emerging company in Silicon Valley is a very exciting development. NUI Galway is delighted to be part of this collaboration which brings mutual benefit to all partners – academic and commercial,” said Dr Jim Browne, President of NUI Galway.
Speaking about the alliance, UL President, Professor Don Barry said: “This alliance and this pioneering commercial agreement highlight what can be achieved with some innovative thinking from supporters of the University. It demonstrates ways in which commercially astute universities and their foundations can benefit through creative collaborations with industry.”

Webinar: Leading the charge – fleet electrification strategies
June 02, 2023
About this webinar
Element Fleet Management hosted a global EV webinar “Leading the charge: fleet electrification strategies” on May 17, 2023. Jason Kazmar from Element and industry experts from Motorq, National Grid, and Cox Automotive provided actionable insights to unlock electrification lifecycle and value by leveraging connected data.
This interactive panel discussion was centered on harnessing data to inform strategic decisions, to optimize battery electric vehicle fleet operations. The speakers provided unique perspectives on EV adoption, operations, and remarketing.
Here are 3 key takeaways from the event
- Take advantage of powerful EV data solutions
EVs on the market today provide multiple insights. Data can be derived from both the vehicles and the chargers. One powerful feature is state of charge alerts while driving. Fleet operators, Original Equipment Manufacturers (OEMs) and utility companies can use connected data to make improvements and benefit the wider industry.
- Optimize infrastructure and costs
Coordination with local utilities is essential for fleet electrification enablement and operational optimization. Data is vital for electric infrastructure (grid) planning and to establish the most cost effective and efficient way to build charging infrastructure.
- Prolong vehicle health and value
The battery is the most expensive part of an EV, representing up to 40% of the vehicle's value. Understanding the state of the battery is important, as it impacts residual value and the usable range over time. The data can help fleet owners to extend battery life span and to determine battery health, so that they can maximize resale value.
Watch the webinar recording to learn more about the value of connected EV data in enabling long-term informed decision making.

Today we put together a channel sounder with capabilities that significantly exceed that system for $600 USD, using off-the-shelf parts and the Atheros CSI Tool, developed by Yaxiong Xie and Mo Li at NTU Singapore. Anh Luong and Shuyu Shi got the system up and running in our lab. The Atheros CSI tool is a hacked driver that works for several Atheros WiFi cards that allow the channel state information (CSI) calculated on the card by the standard 802.11n receiver to be exported out of the card. We used an Intel NUC, which is essentially puts low-end laptop components into a 4 x 4 x 1 inch box. It has two PCI express slots, and we use one to plug in an Atheros AR9462 card (Fig. 1, left). The NUC has two antennas on the inside of its case, but internal PCB antennas like these typically are poor for propagation research (because of a non-uniform and unknown radiation pattern), so we instead set it up to attach our own external antennas by snaking a 200mm uFL to SMA adapter cable from the Atheros card to the side of the NUC case (via two holes we drilled, on the right side of Fig. 1).
|Fig. 1: Inside the NUC-based Splicer channel sounding system|
For one of the projects we're going to be using it for, we wanted directional antennas. The Atheros is a 2x2 MIMO transceiver, so we need two antennas. Also the Atheros card is dual-band, capable of 2.4 and 5.8 GHz. But directional antennas tend to be big and bulky, and too many antennas hanging off of this unit would make it look like Medusa. So instead we attached a dual-band dual-polarization antenna, the HG2458-10DP from L-Com. It is a box that contains two antennas, one vertically polarized and one horizontally polarized. The Splicer tool measures the channel between each pair of antennas, so we can measure the H-pol channel, the V-pol channel, and measure propagation for signals changing polarization in the channel.
|Fig. 2: Two transceiver systems|
Plus it looks like a scaled model of a 1981 IBM PC. Or a minecraft character. I'm not sure.
Why is this $600 system better than the $150,000 Sigtek channel sounder from 2000?
- It's dual band, so we can measure either at 5.8 or 2.4 GHz, instead of being only at 2.4 GHz. In fact, it can measure up to 200 MHz in the 5.8 GHz band, which is a wider bandwidth than the Sigtek system was capable of.
- It's MIMO: we can measure four channels simultaneously. Actually, if we had used a 3-antenna Atheros card, we could have measured nine channels simultaneously. The Sigtek used one transmit and one receive antenna.
- It can make multiple measurements per second, significantly faster than the Sigtek system.
- It is smaller and uses less power. The Sigtek system had to be pushed around on a cart, and when it needed to be battery powered, we had to use 80-pound marine batteries to power it.
Fundamentally, this is just another example of technology scaling over time. The reduced costs ensure that many more people are able to perform research and test new communications, localization, and other applications of radio channel sensing. I hope that the increased focus will lead to new research discoveries, new products, and even further reductions in the costs of radio channel research.


Smok Novo II – The Reasonable E-juice Kit
The SMOK NOVO ultra transportable vaporizer has been launched just lately as a sleek, highly functional vaporizer with an elegant cobra plating surface finish for an impressive vapor creation. The NOVO vaporizer is also known as the SmokeDry electronic vaporizer and is reported to be very easy to use and give a lot of comfort aswell. It is among the latest vaporizers that have come out in the market. With a higher wattage of around 450 Watts, it gets the capability to create a Juul Compatible Pods steady stream of vapors. The device is very compact and small enough to fit in any pocket. The manufacturer states that the SMOK NOVO offers been created for the users who prefer to utilize their e-juice bottles while they are traveling or doing chores, as it can be used anywhere you proceed.

It comes with an ergonomic design for easy dealing with and a smart temperature compensation system. The temp control doesn’t need to constantly change as the battery stops functioning if the existing is applied continuously. It is because the Smok Novo runs through a charging system and when the battery is completely charged it switches on automatically. Also, this advanced technology can help in maximizing the battery’s life time.
With the most recent addition in the range, Smok Novo II, there has been another improvement in its ability delivering capability. It provides the power that is equal to that of the original Smok Novo only with a higher maximum wattage. It offers a higher percentage of voltage at a lower wattage. It offers a higher percentage of battery ability at less wattage. This enables users to use just a fraction of the initial capacity while consuming doubly much strength.
A significant advancement in Smok Novo II may be the ability to regulate the power output. It includes a variable wattage range which allows you to set the exact amount of power necessary for you to achieve the very best results and experience. The power output is immediately adjusted by the built-in electricity control, which features an auto shut off feature. It also offers long-lasting durability. Other state-of-the-art technologies such as for example Quick Lock Technologies and advanced temperature range handles help to ensure a longer-lasting vaping experience.
The new Smok Novo II has a new technology called the Microusb electric battery. It promises a longer-enduring vaping experience with reduced cravings and much easier replacing. Smok has enhanced the proficiency of its heat dissipation through the use of two latest novices, the SMARTYX and Smoktech, which have been specifically designed to work together. The new Smok Novo II has the ability to reach up to an eight mere seconds to heat up period. The SMARTYX pod system spec promises a five moment heat down time with no need to replace the batteries.

How camera traps work
For more on how camera traps work, have a look at our blog entry on The Joy of Camera Trapping…
- Camera Traps let you photograph animals when you’re not around by using a passive infrared heat-and-motion detector to trigger the camera.
- They take colour images during the day and black and white images at night thanks to the infrared flash – which is invisible to wildlife and humans.
- They can be set up anywhere – for example in the garden, field, forest, riverside, garage… and can have fascinating results.
- They can be strapped to a tree or post and record everything 24/7 for many weeks at a time.
- Cutting edge technology means videos and photos are often hi-res, ranging from 3mp – 12mp.
- Digital technology means that the images are ready to view from the in-built SD card immediately.
- Camera traps have a number of names but are mainly referred to as camera traps, trail cameras, game cameras, remote cameras, and scouting cameras.
- They are used by a wide range of professionals, including wildlife enthusiasts, wildlife researchers, game rangers/guides, hunters, and anti-poaching units.
Camera traps have led to significant conservation breakthroughs; click on the links for more information.


Carboncopies Workshop: Review of the Oxford Roadmap on Whole Brain Emulation
THIS WORKSHOP HAS CONCLUDED - MANY THANKS TO ALL OF OUR PARTICIPANTS!
A written summary of the event by Dr. Keith Wiley will be available here soon.
The entire workshop (Updating the Roadmap to Whole Brain Emulation Part 1) is available on our YouTube channel.
The workshop included audience participation. Many thanks to all who RSVPed!
In 2008, the Future of Humanity Institute at Oxford University published a manuscript titled “Whole Brain Emulation: A roadmap”, as the edited output of their first workshop on the science and technology of whole brain emulation that took place in 2007. The manuscript describes many of the scientific and technical challenges to data acquisition, modeling and real-time emulation of a whole human brain, and it attempted to estimate a development timeline.
A lot has changed between 2008 and 2019. Many new insights, a better understanding of the challenges, and some new technological avenues necessitate an updated and corrected roadmap. In preparation for such an update that is planned in collaboration with the Future of Humanity Institute, the Carboncopies Foundation is launching a critical review. Our June 1 online workshop is the kick-off event for that review process, where we will reconvene a subset of the original participants of the 2007 workshop, and include pioneers who have emerged at the forefront of the field.


Mapping shelter deprivation in India using satellite images
Updated: Nov 12, 2018
An approach that combines machine learning with high-resolution satellite imagery to provide new data on socioeconomic indicators of poverty and wealth..
Slums, characterized by sub-standard housing conditions, are a common in fast growing Asian cities. The elimination of poverty worldwide is the first of 17 UN Sustainable Development Goals for the year 2030. To track progress towards this goal, we require frequent and reliable data on the distribution of poverty than traditional data collection methods can provide. However, reliable and up-to-date information on their locations and development dynamics is scarce. New methods are emerging on how to measure poverty, consumption expenditure, and asset wealth from high-resolution satellite imagery that may be able to provide systematic and objective-based measures on where these households are more likely to be found when other data is not available. Despite numerous studies, the task of delineating slum areas remains a challenge and no general agreement exists about the most suitable method for detecting or assessing detection performance.
“The United Street Sellers Republic — the USSR — is the second-largest economy in the world after the United States.”- Robert Neuwirth
In a recent paper, a team of researchers from the Netherlands escience Center, Computational Science Lab at the University of Amsterdam and the International Institute for Geo-Information Science and Earth Observation (ITC) have applied a standard computer vision method (Bag of Visual Words framework and Speeded-Up Robust Features) for image-based classification of slum and non-slum areas in Kalyan and Bangalore, India, using very high resolution RGB images. To delineate slum areas, image segmentation is performed as pixel-level classification for three classes: Slums, Built-up and Non-Built-up. For each of the three classes, image tiles were randomly selected using ground truth observations. A multi-class support vector machine classifier has been trained on 80% of the tiles and the remaining 20% were used for testing. The final image segmentation has been obtained by classification of every 10th pixel followed by a majority filtering assigning classes to all remaining pixels. The results demonstrate the ability of the method to map slums with very different visual characteristics in two very different Indian cities.
The Road Ahead
The study indicates that if we can predict shelter deprivation based on publicly available satellite imagery, this means that when survey data does not exist or is incomplete, we can use earth observation data to making objective decisions about where to focus poverty alleviation programs.
"The SDGs are a bold commitment to finish what we started, and end poverty in all forms and dimensions by 2030. This involves targeting the most vulnerable, increasing access to basic resources and services, and supporting communities affected by conflict and climate-related disasters." UN-Sustainable Development Goal
In the future the team is planning to use temporal satellite imagery to help us understand the dynamic nature of poverty. This would help to detect seasonal variations in vulnerability. For example, we could extract information from satellite imagery that is correlated with changing agricultural yields, inflation, or seasonal floods and droughts. The satellite images coupled with computational models such as this could also predict when households or communities move out of extreme poverty and how slums grow and emerge.

Graphics is a field of computer science in which the research has started but it hasn’t yet been explored to such an extent. The 3D graphics are the updated version of the graphics where the representation of the data is in three dimensional. If we are to compare the 2D and the 3D graphics there are many ways in which they are similar. The algorithms that are used by 3D graphics and the rendering techniques used are adopted from 2D. The lightning techniques that are used in the 3D are used to enhance the 2D graphics as well. The line between 2D and 3D thus is quite thin and often makes Amazon Web Services.
The incredibly early form of graphics in computer systems was proposed by an MIT student in the 1960s. He put forward an application where shapes could be formed with options of storage so that the data could be used for later use. A breakthrough came in the graphics in the 1970s. This was the golden period when the microprocessor emerged. During this time the images could be scanned and then that piece of data could be manipulated in limited yet interesting ways. The concept of curved and motion pictures was made known by this time. This period brought the idea of 3D graphics lighter. The Mackintosh was already in the market which had a GUI (Graphical User Interface). A high-quality program, named TOPAS, enabling animation was making its way into the market. Another software supporting 3D named as “Vol Libre” was introduced in the 1980s which meant a full flash 3D graphic system wasn’t much far. In 1990s a new jump was made to the photo-realistic animation which was the basis for the creation of a complete animated movie for computers. This was a real step forward since now slow-motion and other features were being used effectively.
With all the little accomplishments there always was a little something that didn’t add up quite well and the output wasn’t the one that could change the course of computer graphics. This issue was resolved in the 2000s when the focus became to produce content that was believable. The concept of color images became better known and many companies start investing in the business relating to the 3D Graphics.
increased developments have been made in this domain. The success is in front of us in the form of the high-quality image outputs. The images in this era has state of the art digital effects which are completely believable. The time in which these images are created and the efficiency with which these can be manipulated is uncanny. The development has reached a point where automated games in HD are produced and are being manipulated by the user at run time providing excellent quality.
As an enthusiast you will agree that the domain of graphics has come a long way yet there is a lot that can be further achieved and with the right resources it doesn’t see SharePoint 2019.

3D Reconstructions of Growth Surfaces
Part of a research project that I am involved in requires 3D reconstructions of epitaxially grown crystal surfaces and the quantification of surface roughness. The data is beautiful!
Firstly, overview images of the surface of interest were acquired. The surfaces consisted of calcite crystals that had been dissolved with a 0.5M HCl solution for 10 seconds. As seen below, quite a bit of hummocky topography was created.
Dissolution created ravines on the surface.
After that had been done, a series of images were acquired at different magnifications and tilts. 3D reconstructions and surface roughness profiles were then made:
The image above is a topographic reconstruction of an imaged surface. Below is that same image with digitized lines along which profiles were constructed.
Subsequent data refer to the dashed line in the image above.
Abbot-Firestone curves were then constructed
And additional roughness parameters were calculated:
CREDIT : Molly Pickerel, a former undergraduate in our lab and incoming PhD student at the University of New Mexico- Las Vegas, performed the reconstructions and we worked together to collect the images. Crystal growth experiments were performed by Ellen Olsen.


CELL PHONE MICROWAVE EXPOSURE
It's true that a headset will transmit microwave radiation
up the wire into a person's ear. When a person holds a cell phone up to his
ear, if his head happens to be between the phone and the nearest cellular relay
tower, the cell phone outputs higher radiation to get a stronger signal
through. If a person wears a cell phone on his belt and the phone is turned on,
the phone will periodically send a strong pulsed locating signal to find a
tower and to notify the phone service provider that the phone is turned on and
available to receive a call. Every time the locating signal is sent, the person
wearing the phone gets a slight blast of microwave energy directed to the
internal organs around the waist. If a person talks on a cell phone with a
headset and keeps the phone on his body, his body (and less so his head)
receives the brunt of the microwave exposure.
Comments have been made that the cell phone industry is in a similar position as the early days of the tobacco industry when it knew that its product caused cancer. There is plenty of data indicating that microwave radiation causes adverse health effects from DNA strand breakage to brain tumors. Cell phones now come with a warning that there could be a possibility of health risks. People who want the convenience of a cell phone are not interested in hearing about a possible health risk. Children are particularly vulnerable to health risks of cell phones because the smaller size of their heads in relationship to the size of the microwaves passing through it. (Analogous to second-hand smoke, cell phones emit invisible microwave radiation to those in the immediate vicinity. I hope cell phone usage never gets approved for airplane flights - imagine being stuck on a 3 hour flight next to someone talking away - not only annoying but also being exposed to that radiation the whole time.)
Much research is available on the internet regarding the hazards of cell phones. Here's a link to a brief summary article:
www.microwavenews.com is considered the best source for up to date information on research done around the world on health effects of microwaves and electromagnetic fields.
If you use a cell phone, the headsets that have an empty plastic tube leading up to the head are much safer to use than a wired headset. Some phones now come with a built in speaker phone, and for some phones you can buy a speaker phone which attaches to your phone. You can buy 2 headsets with the tube at the top for $20.99 (RF3 Cellular Headset) at
Cell phones vary in the strength of the microwave signal they emit. A good, reliable and relatively inexpensive ($81.50) microwave meter I have used for years is the MicroAlert. It gives you pause to have a cell phone trigger the meter at 8 or 10 feet away when you've heard a microwave oven also trigger the meter close up. Many cordless phones operate at the 2.4 gigahertz frequency and will set off the microwave meter. Bluetooth wireless technology will also trigger the meter, as will driving by a cell phone tower.

It seems like just yesterday we were talking about spring cleaning, and now we’re moving into the dog days of summer. And it’s hot.
In the 2014 version of ISO/IEC 14763-3, testing of optical fiber cabling, unidirectional testing for permanent links is required. In specific cases, bi-directional testing is required. However, ISO/IEC 14763-3 provides no information on how a bi-directional test should be done - this article explains how.
When Bi-Directional Testing is Required
Testing and characterizing a permanent link with an OTDR requires the measurement of connector attenuations A/B and fiber loss C. To make this measurement, a launch and tail cord are needed (see Figure 1).
Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current. In fiber optics, it defines the direction that light signals travels through an optical fiber.
To properly send data via light signals, a fiber optic link’s transmit signal (Tx) at one end of the cable must match the corresponding receiver (Rx) at the other end.
While it may look and feel like a fiber patch cord, Test Reference Cords, or TRCs for short, are not patch cords. There’s a little something different about these cords that are used for certifying fiber cabling systems to ANSI/TIA, ISO/IEC and IEEE standards.
Recently we have been getting questions about how to determine if an SFP is working. I’m going to use SFP generically here to represent a multitude of the various optical modules that are available. The Fluke Networks fiber testers can be used to measure the light that is being put out by and SFP.
By now you’ve probably heard of 8-fiber MPO plug and play solutions available on the market, which are ideal for Gigabit (40GBASE-SR4) and 100 Gigabit (100GBASE-SR4) applications that use 8 fibers with 4 transmitting and 4 receiving at either 10 or 25 Gb/s.
