Trigger 2 equipments concurrently using GPIB

Trigger 2 equipments concurrently using GPIB

Hi,

 

I'm using 3 equipments controlled by GPIB interface. In one of the applications, I need to trigger 2 of the equipments to start testing at the same time (by issuing TEST command to both equipments). Is there a way to send a single command to multiple GPIB instruments or 'broadcast'? I know I can sequentially send 2 TEST command to both equipments separately, but this will cause delay to the latter equipment and affects the test result.

Look at the GET (group execute trigger) It is a signal on the gpib bus especially meant for triggering more intstruments
