A Broad-Band Signal Generator

Solutions of some of the problems arising in the development of a broad-band signal generator are presented. Three internal cavity, reflex klystrons are used to cover the frequency range. Attenuator and wavemeter designs in coaxial radio-frequency cable are discussed as well as attenuator calibration and accuracy of output power as read from a panel control. The method of pulsing the klystrons is described with emphasis on the problems involved in obtaining very short rise and decay times.
