Hi Scott,
nice plots. Standard deviation of 2ns is very good. You can try to get the
standard deviation down even further by decreasing the EFC Scale slightly. The
goal is to get the EFC variations to be as small as possible since the EFC
voltage is directly related to output frequency.
Also, slightly increasing the EFC Damping will reduce the Sawtooth and
general GPS related errors that may end up on the EFC voltage, so that may also be
interesting to tweak to get the absolute maximum performance out of the unit
while still maintaining stability.
With the best OCXO's I have seen standard deviations down to 1.6ns as
indicated by GPSCon.

Does anyone else have settings, and/or plots, and experiences from their
Fury's that they wouldn't mind sharing with us?
