emulating gpib listener

[fsoutodetal]

Does anybody know how can I emulate a gpib listener circuit, that is, one PC (controller) by USB-GPIB converter controlling a circuit that "simulate" an instrument (listener)?

I need something like this in order to develop a code that controls instruments, even when I don't have access to the instruments (in my house, for instance).

Thanks,

Sounds to me like this is a perfect case for IVI.

OK Dennis,

Thanks for this indication; I'll analyze IVI.

Clearing better, I work with a bench that has about 30 instruments controlled by an old HP computer. So I must upgrade this system with PC and LV.

In order to continue the development in my house (I can't take the bench to my house because it's very heavy, rsrsrs) I need emulate some instruments in my home's computer. In control I'll use VISA, and the system is:

PC - USB-GPIB Converter (Agilent 82357B) - instruments (2 GPIB buses).

In order to emulate an instrument without IVI is a non-trivial task. You would need a GPIB listener at each address so that you would not get communication errors. Simulating responses would be another major task.

One feature of VISA is called VISA Server and this allows you to use VISA resources on a different computer through a network connection. I don't know what it would take to make the test system visible from your home.
