[time-nuts] Re: Manual for Accubeat AR-40A

[Bob Camp]

Hi

The simple answer to the question is that over a reasonably long time period, the GPSDO is right. (assuming it’s a good GPSDO)

How long “reasonably long” is depends a bit on various issues. Measure change on 1 pps outputs over a 24 hour period and you are likely well past any of the issues you are likely to run into.

I have compared it with the output of my BG7TBL GPSDO and the phase drift is incredibly slow, so I have resisted trying to align the two as who is to say which is right?Cheers,Kevin M-HSent from my Galaxy S6 Tablet
