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 w
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 “
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
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 a
