Rubidium source
Finally I have a rubidium 10MHz oscillator to play with. It is a Symmetricom X72 that needs between 10 and 32V input, so the shack supply will be fine. It came built into a case which also has a power and unlock LED on the front plus a fan. Why you ask? Well, I do not really know but I wanted one! Once it arrived I checked it over and powered it up. It took aroud 4 minutes for the unlock LED to go out and it has been giving a constant 10MHz sinewave frequency output since then. The unit has a 1pps input and output plus a serial interface which I have yet to investigate.
