It has been several years..... As I recall, I had several discussions about this with both Ulrich Rohde and later with Fred Walls (formerly the head the NIST phase noise labs). I think the errors we found were related to the calculation of the sideband phase noise and/or the use of a single cw carrier to calibrate a phase noise measurement system. I postulated that the close-in phase noise of the upper and lower sidebands were in fact fully correlated based on my measurements. Fred Walls published a paper to that effect in the IEEE UFFS Proceedings and only gave me credit as a "thank you for the discussions with Jeffrey Pawlan" rather than inclusion as an author.
