Hi

Is the intent to turn this into a product? I’m guessing that’s the idea.

If so:

1) Displaying in scientific notation ( parts in 10^-12 / ppb / ppt )
would be
a useful option for the frequency difference.

2) Adjusting the Tau / gate time would be nice, but not essential.

3) Dumping phase samples to something ( card / USB / ….) so that
things like
ADEV could be calculated would be a plus.

With ground loops an ever present gotcha, just how you get the data
out is
not a trivial part of all this.
