Hello DNadler,Check the magnitude of your FFT output  - bin #1 and #1023 must have the same magnitude, and similarly bin #5 and #1019 must have same magnitude....
For the increased input amplitude (input phase is still Theta_1), let us say you measure PA output phase as Theta_3. By "normalizing on the small-signal phase difference"...
