We have written a program to control a rotator arm, as well as communicate with an HP network analyzer using a GPIB connector. Everything concerning the rotator arm works fine, however we are unable to communicate with the network analyzer. When we try to do anything with the network analyzer, it gives us an error. A screenshot of the error is attached. We're pretty sure the issue is that the drivers we have for NI488.2 and NI common are the wrong versions, but we can't figure out which drivers to use. This shouldn't be a difficult issue to resolve for those experienced programmers out there.
We will be able to provide the code to you.
