Thanks, Bob, I’ll have to start looking now. I’ve been looking for other counters, I only have 5371a x 2 and 5335a x 2 and some other TeK modules. I went back and was reading the time-nut counter thread from 2008 and will have to keep looking for something I want to afford.
Tonight I was plotting one of the rubidium modules Gilbert gave me against my Lucent GPSDO. I was just measuring frequency and I had some glitches that I think are from triggering. The stdev on some 2 hours runs were .0017 with a frequency of 9,999,999.956 average. I have a new power supply coming tomorrow and I’ll be able to move it into a room where I can try to tweak it closer to 10M. The Adev plot of the Frequency was sort of weird looking, sort of like a flattened “U” with the dip around 10E-15. I would have thought it should be more like a typical downward sloping line. I’ll have to read up and see what this indicates. So much to learn, so little time. Thanks for all the pointers. Someone should write a book, “Time-nuttery for dummies”.
