Dual oscillators in Cross Correlated
measurements will also produce a 3dB theoretical reduction in a Phase
Noise measurement system.
Since when?
Its way better than that.
I routinely achieve a PN floor below -170dBc/Hz (I don't have an OCXO
with a phase noise floor below ~ -175dBc/Hz) using a pair of oscillators
each having a PN floor (~ -150dBc/Hz) well above that
