I just recently looked at this at least for the Oncore series of receivers. The magnitude of the sawtooth seems to scale with the accuracy of the PPS. In other words the newer and better receivers have both a more accurate PPS and a smaller sawtooth correction. It makes sense. If less correction is needed the magnitude of the correction is less. The M12 user manual hints at why, they say the newer receiver runs on a faster internal clock. I think the sawtooth correction is always larger than the one sigma error. In other words if you ignore it, then that is the major error in the PPS. Beware of some very old data on this, made back when the UT was new. They still had SA turned on back then. -- Chris Albertson Redondo Beach, California _______________________________________________ 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.
