[time-nuts] Best OCXOs, phasenoise wise.

2010-06-28 Thread Luis Cupido
I'm quite sure someone has went down this road... so I better ask first. Phase noise wise what would be the best OCXO's that we could find around, taken from equipments, or ebay etc. I have in mind essentially the HP ones. the PIEZZO ISOTEMP, CMAK, Vecton(harder to find) and some of the small

I do not think I can answer that question the way you present it. It depends to a large degree on what you want to use it for. If you want to multiply to microwave frequency there are 100 MHz units out there with excellent low phase noise in the $ 400 to $1400 price range, if it is Allan

Hi Output frequency matters quite a bit. What is good phase noise at 100 MHz isn't going to be very impressive at 10 MHz. Frequency offset also matters. Optimizing for -192 dbc / Hz at 100 KHz offset is a very different thing than trying for -155 dbc / Hz at 10 Hz offset. You are unlikely to
