Configuring a Reference Clock
In a phase-locked loop, specify the source for the reference clock so that the frequency stability and accuracy of the sample clock timebase matches that of the reference clock.
Call the niFgen Configure Reference Clock VI or the niFgen_configureReferenceClock function and set the Source or referenceClockSource parameter respectively to the reference clock source. For example, set the Source or referenceClockSource parameter to ClkIn to obtain the reference clock signal from the Clk In front panel connector; set Reference Clock Frequency or referenceClockFrequency to the frequency of the reference clock.
