[OBSOLETE] niFgen_ConfigureRefClockSource

ViStatus niFgen_ConfigureRefClockSource (ViSession vi, ViInt32 referenceClockSource);

Purpose

Configures the signal generator reference clock source. The signal generator uses the reference clock to derive frequencies and sample rates when generating waveforms.

Parameters

Input
Name	Type	Description
vi	ViSession	Identifies your instrument session. vi is obtained from the niFgen_init or the niFgen_InitWithOptions functions and identifies a particular instrument session.
referenceClockSource	ViInt32	Specifies the reference clock source that you want the signal generator to use. NI-FGEN sets the NIFGEN_ATTR_REF_CLOCK_SOURCE attribute to this value. 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 parameter to NIFGEN_VAL_REF_CLOCK_EXTERNAL, the signal generator uses the signal it receives at its external clock terminal as the reference clock.

Return Value

Name	Type	Description
Status	ViStatus	Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. You can examine the status code from each call to an NI-FGEN function to determine if an error occurred. To obtain a text description of the status code, call the niFgen_error_message function. To obtain additional information about the error condition, call the niFgen_GetError function. To clear the error information from NI-FGEN, call the niFgen_ClearError function. The general meaning of the status code is as follows: Value Meaning 0 Success Positive Values Warnings Negative Values Errors
