Hi everyone, As Tom suggested, I redid the test with less than 1 ft. of wire from the PPS output to the GPIO without any logic gates or line receivers. Same result, the SKG25A1 was 2 microseconds ahead of the 58534A. Without any other way of testing, I would probably trust the output of the timing receiver more than the SkyNav module. Anyway the SkyNav board is an inexpensive unit and I wouldn't mind setting an offset in ntpd.
I don't have a scope yet, and a low jitter PPS GPIO is the closest thing I have to a TIC. _______________________________________________ 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.
