Short Name: Ref Clock Source

Property of niFgen

Controls the Reference Clock source the signal generator uses.

The signal generator derives the frequencies and sample rates that it uses to generate waveforms from the source you specify. For example, when you set this attribute to Clock In, the signal generator uses the signal it receives at the Clk In front panel connector as its Reference Clock.

Note  You cannot change this property while the device is generating a waveform. If you want to change the device configuration, call the niFgen Abort Generation VI or wait for the generation to complete.
