White, Richard A.
Abstract :
A system for measuring the gain and phase-shift properties of an amplifier with CW input and a pulsed output is presented. It uses commercially available components in simple circuitry and is free from balanced or calibrated detectors and amplifiers. It is readily automated. Specific equipment used to measure phase characteristics of a 15-kw pulsed traveling-wave tube in the 5.3- to 8.0-gigacycle band is described. Phase differences of 0.1?? are easily resolved.
