Hi
There are indeed “issues” with converting the reference to 1 pps.
If you use a modern D flip flop at the output of the divider these
issues are quite small. There are similar issues with coax cable,
buffer amplifiers, and even the input on the counter. Eliminating /
characterizing them is
Thanks Bob. I was also thinking something similar but on the SRS pdf I
mentioned (high res. freq. measurements), it also mentions Allan variance
and as an example the noise floor data is collected also with a sample size
of 1000. The setup is not like I mentioned but normal ChA/start ChB/stop
Hi
The main disadvantage (if you are after ADEV) is the pre-processing
that takes out the noise you are trying to measure. Getting the repeat
rate so that you actually got samples once a second (after all the overhead
and processing) would be a challenge.
