I need GPIB emulation to set up a mock test bench for my Labview code

[IsraelVaughn]

I would like to do is to make a mockup of instrumentation so that I can test code changes that I make, without tying up the instrumentation itself.  In order to do this I need to obtain or write a software GPIB emulator/simulator.  Do you have any suggestions as to how this would be done?  As far as I know the interface to the NI GPIB card is propietary.  Is there a way to hook the driver function calls and return valid GPIB data?

Thank you,

Hello Israel,

This will be very difficult to do without employing some hardware.  If you were using an IVI driver, you would be able to simulate your instrument.  Or you can have some hardware that could emulate your instrument. 

There are other discussion forums that have talked about similar options.  Take a look at How do I set up an emulator for testing my application and Has anyone done software based instrument simulation.  You could also use NI-Device to create an instrumment that would respond similar to the hardware you want to use.  Unfortunately, there is no simple solution like using a loopback test on a Serial Port.

I hope this helps.  Best of luck with your application.
