NI RF Vector Signal Analyzers

niRFSA_ConfigureReferenceLevel

ViStatus = niRFSA_ConfigureReferenceLevel( ViSession vi, ViConstString channelList, ViReal64 referenceLevel);

Purpose

Configures the reference level. The reference level represents the maximum expected power of an input RF signal.

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.
channelList ViConstString Identifies channels to apply settings. Use "" or VI_NULL to specify all channels.
referenceLevel ViReal64 Specifies the expected total integrated power of the RF input signal in dBm.

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:
