Offline Tom,
Have you run the same sort of test on a LEA-6T, or do you know off the top of your head what the std deviation is? I had naively expected it to be spot on, but I see jumps every now and then, and I don't know whether it's something on my end, or if that's expected.

Pete, Bob, For data on a Resolution-T that I tested see http://leapsecond.com/pages/res-t/ What I found: the raw 1PPS has a standard deviation of about 13 ns; with sawtooth correction that drops to about 6 ns. If that sounds too good to be true, I can double check the raw data, or even re-run the test. I still have the same Trimble board; maybe more than one of them. So my suggestion is to try to duplicate this level of performance first, for each of your two units separately. Only then run the test comparing them against themselves. /tvb _______________________________________________ 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. _______________________________________________ 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.
