Hello time-nuts, I have available a Symmetricom X72 rubidium oscillator with version 5.08 firmware. This firmware has the code to discipline the X72 to an external 1pps input. Unit has been checked out (including 1pps disciplining) and appears to be in good working condition. Oscillator comes with one of the adapter boards just like the non-pps units that we sell on ebay (check out auction 361567934794), pin-6 is jumpered to provide the 1pps to the X72 (pin 19). There is also a link to the manual in the ebay auction which has a lot more on the 1pps disciplining function.
Yes, there are both pros and cons to the X72. Being very small its performance won't match an HP5065A. However, being very small makes it very portable, it has the GPSDO built in (damping can be set from 0.25 - 4.0, time constant can be set from 0 - 100,000 seconds), and power can be 10-32 volts DC. Unit is being offered for $225 and includes shipping to the U.S. First email to s...@rdrelectronics.com wins, I will send you payment information. If you miss this one and would like to be put on a waiting list please let me know, I hope to have more in the future.
