Or like my older all fully working hp's like hp 67, 85, 71B, 91, 21, 25C, 33C, 32S, 28S, 11C, 15C(not this Limited Edition crap), 16C, 41CV and of course it is "full nut" version  and some more... example 67 is after 46 year still working perfectly (only magnetic card reader drive roller had to be renewed because the rubber got old. New rubber and maybe next 46 years but this I can not see. )

RF loop: Had some bad probes give misleading results or fall apart.

|Many probe specs  besides the (often inaccurate) C copm range, Cinput, claimed BW.

1/ Pulse abberation (overshoot, etc)

2/ Phase distortion

3/ Availability of accessories eg typs of ground retun leads, clips, bayonets', adapters

4/ Tip size and robustness

5/ Cable thickness, flexibility (especially poor on some Chinese) replacement cable (some TEK are plug in cable) type of BNC (special pins, shroud, compatibility) quality of BNC, ease of adjustment.


Besides Yokogawa and TEK, we have found a German probe firm PMK many diff/passive/active/current and a   X100  and 1000X safety rated probe.

We have the 100X PHV 100 on order

If you're looking for PMK probes, you can also find them re-badged and sold by Keysight, R&S, LeCroy, Pico, etc.  In particular, the 2.5mm models and accessories are a popular re-badge, and they are fairly decent probes.

But, I would agree they're still not up to the build quality of the older Tek probes, such as the P613x family.

jonpaul:
Mark, we found  PMK probes Very useful in HV and SMPS work where a normal 400V TEKX10 is near limits on 360V bus especially with frequency derating.

Bought PHV2000  made a deal, two like new  EU100

X100 4 kV
