Joe You can check a lot of the functionality from the front panel. Make sure that it works well using the front panel controls before checking that the HPIB interface works.
To check the HPIB functionality you will need an HPIB/GPIB interface for your PC. It is easy to duplicate the tests done by the program on the 9825 tape using Ulrich's EZGPIB (if you use windows). Otherwise if you use Linux or FreeBSD, etc., and have a Prologix LAN/GPIB interface then you can program the tests using Python.
