Those look right, assuming you measured the connectors on the plugin and

they jive with the 0S Lemo size. The only other caveat is that Lemo offered
both crimp and solder contacts. I've only ever seen solder, but it's
possible that those cables were assembled with crimp connectors meaning
you'd have a little more trouble moving them over to some RG-174. Of course
there's also no reason you couldn't just use the existing cable for your
probes; it seems up to the task (shielded, low-Z) and is only marginally
bulkier than the commonly used coax.

How about these?
Thanks for sharing your knowledge, saving me a climb up the connector

You shouldn't need to look too closely. Just measure the OD of thewhat
connector bezel on the front panel. It should be 10mm, making that a 0S
size Lemo jack. The plugs you need to make probes would be part number
FFA-0S-302-xxxxx where the last characters (xxxxx) are all related to
housing material and strain relief options (so pick what you like from

I think you are right about the connectors being Lemo.?? When I get a
chance I'll open the plugin up again and look for a number on the base
of the connectors.

Looks like the ohmeter probes are 2-pin Lemo similar to what Tek used
other places with more pins. The connectors can still be bought,sometimes
at a decent price on eBay, so making up some probes should be prettyeasy.

These photos aren't good but give you an idea what it looks like

later for TekWiki.

Does anyone have any information on a Tektronix TM500 plugin
I think that Tek parts designators that ended in -99 were in-housecalibration units. So it is likely
you will find it difficult to find a manual, or even the
