I agree with Magnus Dual Mixer is the best way to go. That is why over a year ago I set out to develop a system that with counter can be realized for $200. I did reach that goal and Corby tested the first pass and the second pass with 1 E-13 results. He used his SRS counter. Richard who wrote the code for the five PIC's has tested the counter. What is missing some one testing the two combined. I have a total of seven systems out there some on the condition that they get on it with in two weeks. Sad to say it has not happened. I just send out an other kit this week, maybe we will have more luck this time. Once a total test has been done the third set of boards will be ordered and once tested made available for any one. It measures frequency difference and Allan Variance with a resolution 1E-15 the five channel counter runs off USB power and all is needed is along with the reference is a one or ten Hz offset OCXO.
Would be very nice to test.
I will not mention any names but I would like to remind you what you promised the rest would appreciate the availability of a unit that everybody can build and will be affordable.
200 USD is a good price for such a thing.
Attached is the picture of the second pass with HP 10514 Mixer courtesy of Corby. There are only two SMD components! PS I did send it with a picture attached with 113.3 K hoping my text would not take up space but some how it ended up 160K and is on hold. I will try again send only picture!
The picture didn't make it through. If you can put it on a web-page (or send it to me and I put it on my web)and provide a link would be beneficial.
