I am currently using two Keithley USB adaptors for GPIB. I would like to trigger both devices simultaneously using the Instrument Control Toolbox 2.8 (R2009a). Currently, when I issue the TRIGGER command as shown below:

trigger(obj)

only one of the devices is triggered. The example provided in the documentation of the Instrument Control Toolbox also describes the scenario when one device is present.

When I use the application provided by Keithley Instruments, I am able to trigger multiple devices simultaneously.

Is it possible to trigger both the Keithley adaptors simultaneously using the Instrument Control Toolbox 2.8 (R2009a)?

The ability to trigger multiple devices simultaneously using TRIGGER function is not available in Instrument Control Toolbox. The TRIGGER function accepts only 1 interface object as an input and not an array of interface objects.

However, if a time delay between triggering multiple devices is acceptable, then a separate TRIGGER command can be issued for each additional device to be triggered.
