niRFSA_SendSoftwareEdgeTrigger

ViStatus = niRFSA_SendSoftwareEdgeTrigger( ViSession vi, ViInt32 trigger, ViConstString triggerIdentifier);

Purpose

Sends a trigger to the device when you configure a software version of a supported trigger and the device is waiting for the trigger to be sent. This function also can be used to override a hardware trigger.

This function returns an error in the following situations:

• You configure an invalid trigger
• You are in spectrum mode
• You have not previously called the niRFSA_Initiate function.

NI-Scope handles other errors.

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.
trigger	ViInt32	Specifies the software signal to send. You can send a Start, Reference, Advance, or Arm Reference trigger.
triggerIdentifier	ViConstString	Specifies a particular instance of a trigger. This parameter currently is not supported.

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
