trigger - Send trigger message to 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 interface 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.
