Short Name: AI.Lowpass.SwitchCap.ExtClkFreq
Property of DAQmx Channel
Specifies the frequency of the external clock when you set AI.Lowpass.SwitchCap.ClkSrc to 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.
