[time-nuts] Ultra low phase noise floor measurement system forRF devices.

[Mike Feher]

Well, I must admit I did not read the referenced article, but, he is talking
about dBc, or relative to the carrier and not kT. So, if the carrier power
is high enough I suppose it could be done. Even suppose you could measure
it, what would it take to generate such a pure carrier. That may even be
more difficult. -

Hi Bruce,
 
Isn't a -200dBc/Hz floor below the thermal noise floor that can be
achieved?
 
bye,
Said
