IviSpecAn Configure External Trigger [EXT]

IviSpecAnExternalTrigger Capability Group

This VI specifies the external level and polarity for triggering. This is applicable when the trigger source is set to external.

	instrument handle The instrument handle that you obtain from the IviSpecAn Initialize or IviSpecAn Initialize With Options VIs.
	external trigger level Specifies the level of the external trigger signal to trigger an acquisition. The driver uses this value to set the IviSpecAn>>Trigger>>External Trigger>>External Trigger Level property. Units: Volts Default Value: 1.0 V
	external trigger polarity Specifies the slope of the external trigger signal to trigger an acquisition. The driver uses this value to set the IviSpecAn>>Trigger>>External Trigger>>External Trigger Slope property. Valid Values: - IVISPECAN_VAL_EXTERNAL_TRIGGER_SLOPE_POSITIVE - Sets positive slope. - IVISPECAN_VAL_EXTERNAL_TRIGGER_SLOPE_NEGATIVE - Sets positive slope. Default value: IVISPECAN_VAL_EXTERNAL_TRIGGER_SLOPE_POSITIVE
	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.
