it needs a mod. I am tired of this probe cable causing such a problem.
Its likely because its resistive probes and terminating it is problematic. I wonder if you can braze it into a normal connector with a tiny induction or resistance heater to get the center pin on and then use it with a N connector by getting fine silver wire putting it into the center pin along with some flux. If you can spot heat it fast enough you should be able to solder to the fine resistance wire without a problem. I heard its hard to solder. Or to get a small brass pin with a hole drilled in it, that can be brazed to the fine center conductor with a minimum of wire, then solder that into the N connector.
This is also a problem with HV probes. They use some bizzaro ceramic + metal crimped thing for their resistance wire in the leads.
It sounds a little complicated but the discussion about how to crimp that to a metrology grade is also probably insane.

I am almost certain a small pace resistweeze can solder the fine steel resistance wire from a dampened lead to a tiny brass rod that is drilled out with silver, so that it can be treated as a conventional wire. It just needs a long N connector with good strain relief because its going to be a little dodgy. It can make things glow red on high settings. Brass should be acceptable because it has a fair resistance and lower thermal conductivity which makes soldering to it easy. Then you would have a tiny brass nub on the end of that steel inner conductor that can be soldered into a normal connector with the minimum change of impedance. THen you could free your probes instead of having that god damn zerg structure in your lab
I feel like that resistance probe cable is like a massive nuisance to people that wanna do serious electronics in the high AC range. Then you don't need the last known in existence resistive wire crimper, found in some tektronix stock room, to make anything custom.
I don't have one, because the probes are hard wired to it. So you can't put it on a shelf when not in use. Its preposterous. I almost bought this thing 10 times over the last 10 years.
Of course, it would be more stable if you left it alone instead of butchering it to make it modular.
it sounds like any loss of measuring capabilities would be a blow to the fine work its being used for
But there must be damaged units with ripped cables if its build like that. Maybe with a little bit of silver and panel work, its possible to fix them without trying to find new cables, especially if its frayed near the input.
My hunch is
-resistance wire is crimped into a little ceramic coaxial connector, then the outer shield is crimped over it. The inside cable might not be critical , if the long outside cable is all resistance, so it might be possible to replace with normal coaxial if its damaged with minimum effect on the measurement. If you made the cable a little shorter, you might get a hair more resonance. It might be more then acceptable and possible to calibrate out.
Well that one looks like twisted pair, but it should still be possible to fix, even if its two resistance wires, by using a twinaxial BNC.
old resistance wire coaxial probe, another road block
