[time-nuts] Symmetricom X72 interface boards

The X72 rubidium oscillator interface board sets have (finally) been shipped to everybody that paid for them. I had hoped to get them out a couple of weeks ago, but ran into a couple of annoying snags... First, the assembly house built a couple of test articles that were great and were

I have finished my breakout boards for the X72 oscillator. It consists of two boards connected by a ribbon cable (or you can remove a header and replace with a female and directly connect them or solder the boards together). Power input is through a 2.1mm barrel connector. Input caps are

[time-nuts] Symmetricom X72 and Lady Heather results

I'm in the process of adding support to Lady Heather for the Symmetricom X72 (and SA22) rubidium oscillators. I have a most of the functionality working. The X72 has a "health" message that dumps a couple dozen values. The values are labeled with some rather cryptic names that give some hint

[time-nuts] Symmetricom X72 questions

I am in the process of adding X72 support to Lady Heather. The X72 documentation (and the protocol used) is rather horrendous. The available docs are rather old and crusty. Does anybody have anything newer than the stuff on Symmetricoms web site... particularly for the latest firmware that
