IviSpecAn_SendSoftwareTrigger

CVI/LabWindows IVI Class Driver

IviSpecAn_SendSoftwareTrigger

Specific Function

C Function Prototype

ViStatus IviSpecAn_SendSoftwareTrigger (ViSession vi);

Purpose

This function sends a command to trigger the spectrum analyzer. Call this function if you pass IVISPECAN_VAL_TRIGGER_SOURCE_SOFTWARE for the IVISPECAN_ATTR_TRIGGER_SOURCE attribute or the Trigger Source parameter of the IviSpecAn_ConfigureTriggerSource function.

Notes:

(1) If the IVISPECAN_ATTR_TRIGGER_SOURCE is not set to the IVISPECAN_VAL_TRIGGER_SOURCE_SOFTWARE value, this function returns the Trigger Not Software error (0xBFFA1001).

(2) This function does not check the instrument status. Typically, you call this function only in a sequence of calls to other low-level driver functions. The sequence performs one operation. You use the low-level functions to optimize one or more aspects of interaction with the instrument. If you want to check the instrument status, call the IviSpecAn_error_query function at the conclusion of the sequence.

Parameters

Name Type Description
vi ViSession The ViSession handle that you obtain from the IviSpecAn_init or IviSpecAn_InitWithOptions function. The handle identifies a particular instrument session.
