With the TX/RX antennas linearly aligned a full S-Parameter measurement was performed. Both magnitude and phase were recorded at six positions of aperture closure ranging from, no tiles on the screen, tiles on the screen with aperture fully open, aperture 3/4 open, aperture 1/2 open, aperture 1/4 open, and aperture fully closed.
