IviSpecAn Send Software Trigger [SWT]

This VI sends a command to trigger the spectrum analyzer. Call this VI if you pass IVISPECAN_VAL_TRIGGER_SOURCE_SOFTWARE for the IviSpecAn>>Trigger>>Trigger Source property or the Trigger Source parameter of the IviSpecAn Configure Trigger Source [TRG].vi.

Notes

(1) If the IviSpecAn>>Trigger>>Trigger Source is not set to the IVISPECAN_VAL_TRIGGER_SOURCE_SOFTWARE value, this VI returns the Trigger Not Software error (0xBFFA1001).

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

	instrument handle The instrument handle that you obtain from the IviSpecAn Initialize or IviSpecAn Initialize With Options VIs.
	error in (no error) The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
	instrument handle out The instrument handle that you obtain from the IviSpecAn Initialize or IviSpecAn Initialize With Options VIs.
	error out The error out cluster passes error or warning information out of a VI to be used by other VIs. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
