trigger
(To be removed) Send trigger message to instrument
This visa
and gpib
object function will be
removed in a future release. Use visadev
object functions instead. For more information, see Compatibility Considerations.
Syntax
trigger(obj)
Arguments
| A GPIB, VISA-GPIB, or VISA-VXI object. |
Description
trigger(obj)
sends a trigger message to
the instrument connected to obj
.
Tips
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.
