Hi
It varies from 5370 to 5370. You see a lot of plots that run out to 10 samples
or less. Anything below 100 samples
is risky in so

Hi
There are a number of ways to improve the resolution (and accuracy) of your
data without spending
big piles of cash. They have been discussed here on the list many times over
the last few years.
What I’m suggesting is that you dig into that ahead of taking data. You will
dive into it

Is that true if I'm
Hi
The most basic issue you are going to run into is that your counter is not high
enough
resolution / accuracy to give you meaningful data for time intervals under a
few hundred
seconds. I would focus on improving on that part of things before I went off on
a major
“test everything”
MY AIMS
1) Try to learn about the various statistical tests (ADEV, MDEV etc), and
how best to compare oscillators, by making some measurements on various
oscillators I have.
2) Investigate the short/medium term stability of the output of various
bits of test kit. All are locked to GPS by
