C Function Prototype

ViStatus IviFgen_ConfigureRefClockSource (ViSession vi, ViInt32 referenceClockSource);

Purpose

This function configures the function generator's reference clock source. The function generator uses the reference clock to derive frequencies and sample rates when generating output.

Note  The function generator must be in the Configuration state when you call this function.

Parameters
