I'm not exactly sure what the problem is, but any queries to the power supply will return garbage. Using John Miles' Prologix.exe GPIB configuration utility http://www.thegleam.com/ke5fx/gpib/readme.htm#prologix When I do a simple ID?, the 6034A supply floods the program with what appears to be the <CR> character. The program will not accept any more commands and the windows hourglass is seen when the mouse is hovered over the Proligix.exe program. I have to shut off the power supply to get the program back under control. I did do a firmware update about 6 months ago, but I see there's been at least one update since then. I'll update the firmware again and see what happens.

Try to talk to the power supply using Hyperterminal. A GPIB-equipped box should not respond with a barrage of nonsensical data. What happened with mine was that the responses were ok but one bit was stuck. So I always got a time-limited set of data but when deciphering it the information in the data sounded like Swahili. Sending was never a problem, receiving was because the Prologix threshold sits around 3V and that's way too high for old bipolar TTL. And that's what most vintage gear will have inside. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM. |
