BobThe Phase noise of that GPDSO seems quite high and some form of filtering
(bandpass or low pass) of its output may be necessary to reduce the resultant
jitter when connected to the 5370A input.There are commercial TDCs that claim
that sort of

That doesn't seem inconsistent with the specs given the contribution of the
5370A to the measured ADEV is likely to be of the same order as the PRS45A
spec. The ADEV of the GPSDO also needs to be taken into account. The
contribution of the 5370A to ADEV will gradually become insignificant
I hooked up my PRS-45A yesterday, just to do some ADEV comparisons with my
GPSDO. Unfortunately, the GPSDO seems to be better by almost two points at all
tau as measured on my HP 5370A and plotted by Timelab. So, can I infer from
that that the OCXO in the PRS has a problem, or could it be
