Hi:
After many years of not knowing enough to buy these, I am now stocking up. And scope probe to BNC adapters have been a big revelation too.
So this is the N2890A Passive Probe that came with an Agilent scope I bought a while back:
If you look at parts, (can't seem to post a working URL) it shows the dual lead adapter as $6.09 and the PCB socket adapter as $24.38
Well, the dual lead adpter is *made from* the socket by having someone solder wires on and heatshrink it!
So the socket if anything should be cheaper! I think it's an error.
I am trying to buy up all the adapters, but their stupid web store won't let me enter my billing address, which it already has, but says it doesn't.
So now I am looking for alternate suppliers of 5mm scope probe tip
BNC adapters dual lead adapters PCB sockets
I have found a few sources, but the bare PCB sockets seem to be the hardest to find.
It seems there are subtle differences in the probe tip diameter and taper than can make using 3rd party probe tip accessories problematic.
Beware if you use adapters whether or not the inner contacts are getting pried apart by an over sized probe tip, or even making reliable penetration depth.
Note that even adapters supplied by the probe maker (like Agilent) might damage their own adapter, because the probe tip might be larger than some other model that the adapter was actually designed for, but they cross referenced it to the new probe without checking little details.
