As usual, I'll reply with a bunch of questions which will enable us to
guide you.
1) What is your intended frequency range?
2) How about a picture of the choke as well?
3) The picture of your inductor offers quite a bit of coupling potential.
Generally only a hairpin or 1 to 2 turn inductor is held close to the choke
under investigation.
4) Realize in-circuit measurements are biased by directly surrounding and
connected components. Can you lift only one end of the choke for
measurement?
5) Could you please attach the image of the sweep from your VNA of the
choke measurement?

I have a RF choke in a TS-530S that I'm trying to test for induction and
frequency. I saw the methodology of building a loop to go around a coil to
read this. I really don't want to remove the choke, it's old and fragile.
I made a partial loop, see image, and was able to get a frequency from it.
I don't know anything about this, it was an experiment. Does anyone have a
more educated idea about the test?
