What error? I'd say one DDS step. The steps are in units of about 5.6E-13 so the max error is 1/2 of that. How long to measure. The PPS will be random the worst case will be that it is 30 seconds off. That could take a LONG time. I think it is best simply to measure the PPS offset from UTC and leave it. Just get the 10MHz right and the PPS will keep a constant known offset. Any timing application will have a way to enter the offset. If you really do want to move the phase of the PPS. I think a fast way might be to turn the FE5680 off then back on, repute until you get "close". -- Chris Albertson Redondo Beach, California _______________________________________________ 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.
