The phase noise (really short term stability) of a rubidium oscillator is rather poor compared to on ovenized quartz oscillator. So what I really want is a strontium disciplined OCXO.
- mjb 13y agoYears ago I was involved in some work on clocks that needed very high performance at low cost. We ended up with OCXOs GPS-disciplined over some of their frequency and atomic clock disciplined (cesium, IIRC) over another part of the range. Telling the time is hard.
- madengr 13y agoCool. I bought a couple of HP Z3801A recently for home lab use. Also have an Arbiter GPS disciplined clock at work as a frequency standard for my RF equipment; they use one of the Wenzel OCXOs that has the lowest phase noise you can buy.
