Re: [time-nuts] Re. DIY atomic "resonator" 6GHz synthesizer from ADI

But it is as Richard said and after he sent it I remembered reading about it in the "Quantum beat". The trick is to get that accurate frequencies sideband to land on the RB or CS frequency. Just 1 sideband. So using a large step synthesizer and then another to get the finer detail is a reasonable

Re: [time-nuts] Re. DIY atomic "resonator" 6GHz synthesizer from ADI

Hi If you make the cells in the basement (or even in most factories) the ability to have a wide range synthesizer will come in handy. The whole “6.834xxx GHz” thing is dependent on a number of variables. It is not at all uncommon to produce cells that come out 10’s or 100’s of KHz off of the

Re: [time-nuts] Re. DIY atomic "resonator" 6GHz synthesizer from ADI

You always want two frequency sources. One generates a carrier frequency offset many MHz from 6.834 GHz and the other frequency source modulates the carrier with a sideband that is at the exact ~6.834 GHz frequency that finds the atomic line. The sideband is in turn modulated with audio to find

Re: [time-nuts] Re. DIY atomic "resonator" 6GHz synthesizer from ADI

When I read about the frequency generation in the Rb or CS there are normally many numbers associated with the actual frequency. Down to at least the 1 Hz level. Many of these PLLs are intended for multi-KHz steps. I speculate you might need 2 PLLs one thats very fine in I hz increments that gets
