How to sync 4156A parametric analyzer with Agilent 81110A pulse generator?

[synchronous]

I am trying to synchronize Agilent 81110A pulse generator and HP4156A parametric analyzer ( it doesn't have a PGU unit).  The goals is to measure the data from parametric analyzer when at the time 81110A triggers a pulse.  I really appreciate your help.

You've got a hardware issue and the best source of information would probably be Agilent. That being said, if you are using GPIB, you typically have two means of synchronization. One is hardware triggering and the other is software tirggering. If you want the analyzer to run when the other instrument outputs a pulse, if the analyzer has an external trigger input, you would wire the pulse output to the trigger input. Software triggering can be done with the GET (Group Execute Trigger) command. After configuring both, when the GET is issued, both instruments would be triggered at the same time.

Thanks you very much for the reply. I have searched for GET function and I found " GPIB Trigger Function" and "VISA Assert Trigger". The parametric analyzer and pulse generator parameters are set up. In order to trigger both devices, I am trying to write GPIB commands ":PAGE:SCON:SING; *OPC;" for parametric analyzer and ":OUTP1:STAT ON;" for pulse generator at the same time as GPIB trigger function.  Is this the right function to use?   Can you please direct me how to trigger the two devices and write two commands in parallel?

You can't write two commands at the same time. The idea of a trigger is to initiate a measurement/generation. If the instruments support it, you would configure them so that as soon as the trigger is detected, they would perform the programmed operation. For example, you might be able to send the 'ON' command and it will wait for the trigger before actually outputing anything. I don't have the instruments or the manuals. You will need to study them to see what options are available. Or, as I said originally, contact Agilent.
