Hi Ok let's toss some numbers into the mix.
The counter time base one day after calibration is in the 0.5 to 1.5 ppb range. The LPRO ten years after it left the factory is in the 0.5 to 1.5 ppb range. The GPSDO when running properly should be in the 0.005 to 0.02 ppb range at one second. One ppb at 10 MHz is 0.01 Hz. It also is a the resolution limit on a 5335 at 1 second.
