Abstract :
Line-up and maintenance of radio relay systems require sensitive yet rapid measurements. These are obtained by scanning the systems response as functions of time, frequency, and amplitude. Parameters thus scanned include the transient response to step functions; frequency characteristics of gain, phase, impedance and their frequency derivatives; and amplitude characteristics of output nonlinearity and of intermodulation products.
