Gregory explains how Phase Noise below the measurement setup noise-floor is measured, using two separated analyzers and cross-correlations in the frequency domain.
Some methods of Phase Noise measurement are limited by the analyzer own phase noise profile, as its own noise adds to the measured signal, corrupting its profile.
Using two separated analyzers, with uncorrelated noise profiles, it is possible to perform cross-correlation that uncouple the measured noise from the setup added phase noise.
