Thanks. The ebay listing is for the pressure transducer part of the probe set I have. Definitely labeled as Tektronix gear. The probe assembly has a Lemo power cable and a P6137 style BNC connector and body. Maybe it was a custom probe for internal use or a particular customer. Just trying to figure out if I can use the probe amplifier for anything interesting but I'd definitely need to find a schematic first.
