Hello All, Anyone have the manual for the HP 3437A Voltmeter? Also, what kind of funky BNC connector does it use?
Thanks Mike

It looks like a three-lug Triax connector to me. Used by a lot of Keithley test equipment. Two shields. The inner shield sometimes driven and called a "guard". Good for very low level high speed measurements. You should be able to get an adaptor to BNC.

Steve, Thanks so much, I've never seen one like that before. You think I could just replace it with a BNC connector?
Thanks Mike
Yes, I think so. Probably want to use the outer shield and leave the inner one unconnected. Would be a lot cheaper than purchasing the Triax-to-BNC adaptor, which I believe also doesn't use the inner shield. I have purchased them before at the day job - I think from either Newark or Allied.
FWIW - to make matters worse, there are two-lug Triax as well as three-lug! Keithley equipment uses both kinds. Triax jumper cables are quite expensive, but I found the connectors themselves and the cable aren't too bad $ and have started making them myself - but they are very difficult to assemble.
