The "multistep" jitter seen on the PPS plots is a deliberately induced high frequency jitter. The effect is to "rough up" long hanging bridges so they become oscillator wander in GPSDOs. Pretty analogous to Floyd-Steinberg dithering an image really. I have tried to implement the same basic idea with both Oncore and PRS10, by sending commands via the serial port to move the PPS pulse around but got mediocre results. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] -- To unsubscribe send an email to [email protected] To unsubscribe, go to and follow the instructions there.
