float: Specifies the frequency of the external clock when you
            set **ai_lowpass_switch_cap_clk_src** to
            **SourceSelection.EXTERNAL**.  NI-DAQmx uses this frequency
            to set the pre- and post- filters on the SCXI-1141,
            SCXI-1142, and SCXI-1143. On those devices, NI-DAQmx
            determines the filter cutoff by using the equation
            f/(100*n), where f is the external frequency, and n is the
            external clock divisor. Refer to the SCXI-1141/1142/1143
            User Manual for more information.
