The good Lady Heather's GPS Disciplined Oscillator Controller Program calculates and plots (also writes the results to the log file) ADEV and OADEV of the Thunderbolt's reported error estimates. My comparison of these "auto-ADEVs" to the values generated from a Tek DC5010 counter showed they

Maybe this should be the subject of a separate thread but to enable ordinary time-nuts to be able to test their ocxo's and gpsdo's for phase stability at "home", what would it take as a minimum to be able to perform something like an ADEV test? This would enable us (the other half) to see the resul
