RF Pulse Measurement Techniques and Picture Quality

One of the most critical performance characteristics of the TV antenna system is its ability to transmit "ghost-free" pictures. It has been shown that the amount of reflection from the antenna can be correlated to picture quality. How the vestigial sideband RF pulse technique, developed by RCA, more closely simulates TV operation than any other method is discussed. The selection of optimal RE pulse-widths to best reflect correlation with picture quality is discussed. Two RP pulsewidths, one of long duration (up to 2,¿s) and the other of shorter duration (0.25, ¿s), are recommended for use in antenna test measurements. The RF pulse testing procedure can also be used for measuring the color performance of antenna systems.
