trigger

Send a trigger message to the instrument

Syntax

• trigger(obj)
  

Arguments

obj	A GPIB, VISA-GPIB, or VISA-VXI object.

Description

trigger(obj) sends a trigger message to the instrument connected to obj.

Remarks

Before you can use trigger, obj must be connected to the instrument with the fopen function. A connected instrument object has a Status property value of open. An error is returned if you attempt to use trigger while obj is not connected to the instrument.

For GPIB and VISA-GPIB objects, the Group Execute Trigger (GET) message is sent to the instrument.

For VISA-VXI objects, if the TriggerType property is configured to software, the Word Serial Trigger command is sent to the instrument. If TriggerType is configured to hardware, a hardware trigger is sent on the line specified by the TriggerLine property.
