Hi!Has anybody a solution how to trigger two or more HP3458A digital multimeters simultaneously.Either in Labview or using External triggering. The LabView's Group Excecute Trigger - GET nor *TRG does not seem towork with these multimeters. *TRG is not supported by this multimeter according to the manual. The main point is that one multimeter is measuring voltage and the other current.External TTL pulse should trigger multimeters simultaneously, but this is only if both measure current or voltage.It seems that the delay after getting the trigger command (either external or from software) is bigger when measuringcurrent thant when measuring voltage. And this delay difference stays even when multimetersare forced to use same delay using DELAY [second] command.Any ideas how to solve the problem?

Instrument Control (GPIB, Serial, VISA, IVI)

Check out both systems to arm and then use GET (Group execute Trigger) to start the conversion.

It is a triggering on he GPIB bus that is send to all devices that are waiting for it.

greetings from the Netherlands
