Hi If you hook up a pps into your 5334 from the GPSDO as the “start” and a pulse from the Rb as the “stop” you will get about 2 ns resolution.
Tau zero is the sample time used. 3,600 sec sounds a lot like a sample per hour. If you have a tag each hour your resolution is 2x10^-9 / 3600 = ~6 x10^-13. ====== Given what we now know about the sensitivity of the C field, things like humidity may indeed be part of the long term drift ….
