Hi A dual input counter is probably your best tool. Something like a 5335 or 5334 would be reasonably cheap. Maybe compare edge crossing time to a pps. Mux all of your outputs and compare them one at a time. You will have data resolution at 1x10^-12 in under a day.
For time slips (as in dropped cycles) you likely would want to divide them all down to 1 pps (or less) and compare there. Of course that all makes a lot of assumptions about what you need to do.

Further, what timing/health metrics could/should I be aware of and/or looking for? I do not want to spend good money on another oscillicope if I can help it, but I do want to see, or at least be remotely aware of clock slips/walks and other anomalies. I am thinking about building an embedded system to automate monitoring, configuration, and alerts... perhaps using an Arduino. -CH _______________________________________________ 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.
