SCPI commands allow you to interface with a Oscilloscope. For example, Set the vertical scale for channel 1 to 500 mV/division to measure a signal with an amplitude of up to 2.5 V. Would correspond to `:CHANnel1:SCALe 500E-3`. Write me the SCPI command corresponding to "Set the time base (horizontal) scale to 10 microseconds/division for analyzing a signal with a period of 100 microseconds". Give me the command in a JSON value with the key being the natural language and the value being the SCPI command
