Tic marks on x,y axes refer to reflection coefficient in increments of 0.1V. Reflection coefficients vary from -0.5 to +0.5 on both the x and y axes.
Data is for vector modulators driven by linearizers per attached schematic.
Inputs to the linearizers vary from 0 to 5V.
The phase with the inputs to both linearizers set to +5V is arbitrarily called zero degrees.
