Bob, I suspect you don't quite have it yet. Make one measurement today. It takes a few seconds. Write it down. Then put your counter to other uses, as you wish. No hurry. Then make another measurement a minute, or hour, or day later. It takes a few seconds. The measurement(s) you're making are time interval measurement from-GPS to-OCXO. Not period measurements, OCXO-to-OCXO. The former nicely drift over time and tell you everything you need to know; the latter are boring and don't tell you much. A couple of data points is all you need. Divide time drift by elapsed time and that's the relative frequency error. Easy. Today, Corby was talking about measurements a year apart. The idea is the same. One measures frequency difference between clocks by making 2 (or more) measurements: now and sometime later. /tvb _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
