Hello everyone!
Thanks for all the great responses. I looks like it will boil down to
creating something own.
@Florian:
Excellent idea with the DIL socket! I already thought about putting
together something own, but those sockets for the tip connection didn't
come to my mind. Other probes suitab
> I just looked at your mentioned Textronix probe Phillip.
U shouldn't use such a probe if you want low interference because it has a very
high RC load in the R component. Maybe U should use a classic 10M Ohm probe
instead and connect that to a 1 MOhm scope?
My impression is that your probe is

Philipp? At those frequencies U mention U just need a simple pin and a common
ground point at your card to make the measurement. In my days as an RF repair
engineer i hooked my probe at those points with my integrated

This is most probably not an option, as Philipp has to minimise the
influence of the probe on the signal. But the SMA connector might be a
good idea, still.
A SMB jack has a outer diameter of about 3.6

Do you have other probes available as well? It's much easier to find
these adapters for 2.5 mm probes.

I'd take a small PCB with copper on both sides, drill a couple of holes

Unfortunately, amplitude is quite
It is possible to hold probe a little bit above the point, amplitude will
however not be accurate. Rugoski coil is also useful for high frequency
measurements of currents but not low frequency or DC.

Hi everyone,
please excuse this question very unrelated to LinuxCNC, but I know that
here are quite some people around who are familiar with scopes and
high-frequency measurements. Some who like Tek and some who don't ;)
Anyway, I've got a project where I need to measure signals with
frequencies

Or is it just me?

Most modern converters are class D
Wallace,
Just a FYI, I got the email. Watched a couple of others, and I'm
planning on watching the whole series. Not that I'm likely to ever own
a water jet cutter.

Yes a shield has two primary jobs but ground impedance is far from zero at
high frequency. The shield will not stay at fixed potential at high
frequency for a noise source.
If there are three-phase input and a ground Cable summed current thru all
four may be zero but there may be a current flow fr
