Hi Bob,
I'm seeing 4.22E-12 as the slope value in the upper right of the TimeLab
phase difference plot. Is that telling me that my DUT is within +4.22ps
/ sec from my reference 1PPS for the 24 hour measurement duration?
I have attached a screen capture that will hopefully make its way
through for viewing.
Thanks,
Chris
==================================
Chris,
Just looking at the graph reminds me of a daily variation - perhaps due to
temperature. Is that likely? Would a two-day graph be worth doing in this
particular case?
Cheers,
David
