Both the GPS and DS32XX 1PPS should be fine. Are your free-run counters really free? It looks like a simple bug in your code. All this is very easy to debug if you have even the most basic frequency or time interval counter available to independently validate the GPS or the DS32XX 1PPS interval. /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.
