niRFSA_ConfigureRefClock

ViStatus = niRFSA_ConfigureRefClock( ViSession vi, ViConstString clockSource, ViReal64 refClockRate);

Purpose

Configures the NI-RFSA device reference clock.

Parameters

Input
Name	Type	Description
vi	ViSession	Identifies your instrument session. vi is obtained from the niRFSA_init or the niRFSA_initWithOptions functions and identifies a particular instrument session.
refClockSource	ViConstString	Specifies the reference clock source. OnboardClock Lock the NI-RFSA device to the NI PXI-5600 onboard clock. RefIn Lock the NI-RFSA device to the external REF IN connector on the NI PXI-5600. PXI_Clk10 Lock the NI-RFSA device to the PXI backplane clock using the NI PXI-5600. You must connect the PXI 10 MHz connector to the REF IN connector on the NI PXI-5600 front panel to use this option.
refClockRate	ViReal64	Specifies the reference clock rate, expressed in Hertz. The default value is 10 MHz, which is the only currently supported value.

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 examine the status code from each call to an instrument driver function to determine if an error occurred. To obtain a text description of the status code, call the niRFSA_error_message function. To obtain additional information about the error condition, call the niRFSA_GetError function. To clear the error information from the driver, call the niRFSA_ClearError function. The general meaning of the status code is as follows: Value	Meaning
0	Success
Positive Values	Warnings
Negative Values	Errors
