Hello Mark,

thanks for your info.
Does your actual version 5.0 also support the X72 rubidium oscillator?
And if not could you please send me your modified version for the X72?

Thank you in advance and

kind Regards

Chris

> Symmetricom sold some interface boards for the X72.   They are 0.32-ish inch thick PCB's  with a dual sided edge tab pattern on them.   The PCB edge tab will insert into the connector on the X72.  The interface board for my X72's only breaks out 12 pins...  a lot of Ebay X72's come with that 12 pin connector board...  I think that they were pulls from some piece of equipment.   My X72's only had 250 hours on them.

> I have been thinking about laying out an X72 interface board that has the edge tab broken out to a standard 26 pin 0.1" pattern,  a RS-232 inteface, BNC's for the 10 MHz, ACMOS output,  1PPS in,  1PPS output, etc.  The board would also have a way to connect it to the SA22.

> Lady Heather now talks to X72's (and probably X99's and SA22's).   I have implemented a disciplining algorithm for use with X72s that have the older firmware that does not do disciplining... like probably 99% of the X72's out there.  Symmetricom's code only seems to keep the 1PPS aligned with 300 ns.  My code attempts to keep it within 100 ns.
