Measurements are taken in discrete steps in theta and phi direction. Data is being recorded using a network analyzer (passive)for both theta and phi polarizations at each position resulting in a 3D gain pattern. Gain is derived directly through spatial averaging of VNA S21 measurements (passive measurement).
