I have a bunch of small feedthru caps that I need to measure their Zo
to assure it's 50 +/-10 ohms. Any thoughts on how to do it? I'm going
to try to put a 50 ohm load on them and look at them with a network
analyzer. I should be able to get it's Zo from the VSWR, no? Any other
ways?

Feedthrough caps are designed to be low inductance caps to ground- typically
used to ensure no RF gets through on DC or bias lines. Never heard of a 50
Ohm designed feedthrough. My junkbox is full of 0.001 and 0.01 feed
throughs. To be 50 Ohms it would need to be coaxial in nature- they may
exist but never saw one. Bulkhead barrel connectors would fulfill that
requirement.
