I tend to see GPIB errors pretty frequently when I do that, for some reason. For long-term tests it may be less frustrating to limit the rate to 1 PPS. Also, you need to measure the actual tau interval when the counter free-runs like that, which is an extra complication. It won't be something nice and round like 100ms or 1s. -- john, KE5FX _______________________________________________ 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.
