RF Metal Housing Pins

I have googled many times on internet but could not find the type of connectors are used for supply and ground in atteched pic.

Sorry, in German language only, but here is the datasheet for similar feedthrough cap and ground pin from my supplier:

tusconix makes those EMI flitercon feedthrus.

I would say you solder wires to these pins.

is that what he meant? LOL. well yes of course you wrap a wire around the pin, and solder it. the pins are designed to stand far enough away from the housing so that the housing is not a big heat sink for the soldering operation.

For short term measurements, you can clip on "J Hook" type wires. Just be careful, the one for the DC voltage is pretty fragile and can easily be broken off. the ground pin is much more rugged
