The board has a place for range limiting resistors on the ends of the pot.
In one test that I did using a supposedly very good pot, I found that the pot
did not have a balanced tempco between the wiper and the ends. I spent a week
finding that out.

It may not be the best way but what I do with an
LPRO is use a 10-turn pot and set it to the center
of its range then adjust the internal pot to give
me an output of 10 Mhz. Basically that gives me a
voltage divider where the top and bottom resistors
have the same TC so the offsets pretty much canc
My adapter board for connecting an LPFRS / LPRO / OCXO to my BNC (and now SMA)
connector board has a place for a 10K EFC adjustment pot (0.375 x 0.175"
footprint). I'm looking for recommendations for a cheap, low-ish tempco pot.
I have a few nice ones with a house number on them, but the Bou
Luciano,
Not sure what you mean by "two measures made on the same DUT never
coincide".
The plotter program takes out wraps which since your phase gain is so
large are due to happen.
For lower Tau measurements just adjust the phase for close to equal and
run shorter plots.
These can be spliced
