Hello,
The first thing I wanted to verify with you is what GPIB board you have. You will only be able to use the GPIB Analyzer with a GPIB+ board. These boards can be found at the following link.

Also, if you do have one of these interfaces, then I need to request more information, such as the driver version and OS you are using. Also, are able to communicate with your instrument successfully in MAX?
Hope this helps!
Regards,
