[time-nuts] GPS Locked and Unlocked Performance Comparison

[SAIDJACK at aol.com]

Hello Tom,
 
excellent web-page! That looks like a lot of work was done.
 
Would you have data for 24 hour hold-over performance (86400s ADEV)  for 
these units?
 
thanks,
bye,
Said

Sifting  through old data, in addition to recent measurements
made in the past few  months, I have 4 very interesting plots
of GPSDO performance.

The  goal was to see real-life plots of disciplining in action by
contrasting  free (unlocked) vs. GPS-locked performance as
compared with my 10 MHz house  reference. The four GPSDO
measured so far are: Z3801A, Fury, Thunderbolt,  and Miller.

Comments  & questions welcome.

I hope to measure quite a few more this year.  Contact me
offline if you want your favorite one included in the list.  Note
that I'm not necessarily looking for the best GPSDO; instead,
for  this page at least, the more variety the  better.
