Will your software work with an official GPIB-USB adapter or the Ebay clones thereof?

I normally use it with an official Prologix adapter. Note that this software does not work with NI-VISA type adapters. Only adapters that support the Prologix command set.  It's been used with various Prologix clones with mixed results. See my web page for more info.

Thanks for the SW, lmester. Fantastic job. Just tried it with Girlando's  Arduino GPIB and it works a treat. Just had to modify the Version ID that the UI is expecting and that was pretty much it (Settings -> Default Settings)

I was really worried for some time now, that the battery in my 3478 would die on me. Well, not any more.   :clap:

HighVoltage:
Nice looking software !
May be one day to can also make it work on the 34401A? How cool would that be !

Hi lmester,

I just tested this software with the USB to GPIB adapter made by Steven Casagrande, link below and, as expected, it doesn't work. How hard would it be to add this adapter to the list?

Edit: Never mind, it works. Thanks a lot !  :-+
Edit1: For some reason, even though I can see the readings from the instrument and (sometimes) I can control it, the message is "Instrument comm fail. Check GPIB port setting". It also cannot read calibration. Could it be because the GPIB adapter requires 460800 baud rate? In the "Default settings" it doesn't accept it but if I set it by hand in the config file, it doesn't complain.
