Chuck, I have used my HP 3478A with my Prologix controller (and several other GPIB controllers), but I have not upgraded the firmware to 5.0 (I think I am still at 4.61 or something like that). I will try and let you know.
The 3478 is a relatively recent instrument (as far as GPIB features/capability/compliance is concerned), so I am surprised you would have problems.

Hi Gang! I just bought a Prologix GPIB <-> USB converter model, version 5.00, and I am having some problems. It works fine on some of my instruments, but it just locks up when I hook it to an HP3478A DVM. The DVM is known good, and works great with my HP85B (doesn't everything?). Basically, if I do any commands that require bus activity, the Prologix locks up and refuses to respond to even the ++ver command. When I unplug the HP3478A, the Prologix once again finds its happy spot, and responds normally. Any ideas? -Chuck Harris _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. -- No virus found in this incoming message.
