'scope probe ground spring.

Hi all, I'm doing some relatively (for me) fast stuff. I get ringing from the x10 scope probe ground clip wire, and I end up making my own little ground rings from bus wire that I solder to my bread board.



Like this,

I was thinking that it would be nice if someone made these for me. Maybe some phosphor bronze springy stuff for the ground connection, there could even be an insulated terminal for the pointy part of the probe. I could then tack these down near the parts of the circuit I want to probe.



Does anyone know of such a beast? And what should I search for?



TIA George H.

I think 5mm fuse clips work to clip onto the probe barrel, and you can solder a little wire to that.

Sounds like a specific type of "PCB test point". One example is

Thanks, I do end up making them myself... just thinking it would nice to have a pre-made thing I could stick down onto copper clad. Having the isolated center terminal attached would be a big bonus.

Hmm sort of, I was thinking of something horizontal... this looks about right.

but maybe the wrong size...

Thanks you've given me a bunch of words to search with.

I made an RF probe with a fixed pin adjacent to a pogo pin, . The pogo is long enough that you can usually reach ground at different distances by holding it at an angle.

You can also buy coaxial pogo-pins. I have some here, scavenged from a 900MHz modem test-set.

I realise it's not quite what you want, but the idea might be useful

Here's an insulated one (N2789A):

FWIW, I've never tried to solder one.

They come with some high speed scope probes....
