Sounds like one of your 1-pps sources is dropping out for long periods of time, presumably the one connected to the STOP channel. If it receives a START trigger but no STOP trigger within 10 seconds or thereabouts, it will give you an Err 02. The list of error codes is on page 3-4 of David Kirkby's scan (available on agilent.com). -- john _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
