An Instantaneous Pulse Signal Analyzer

Abstract

With particular reference to radio countermeasures, a novel method for the analysis of pulse-type radio signals is described which makes use of a special five-gun cathode-ray tube wherein each sweep is triggered simultaneously by the signal to be analyzed. The range covers signals having(1) pulse widths from 0.25 to 1000 secs, (2) repetition rates from 20 to 10,000 cps, and (3) other complex wave forms of a nonlinear nature. Since modulation characteristics are presented instantaneously on the screen of the tube, it is possible to analyze signals of extremely short duration. After preliminary research, several instruments of this design were completed and used successfully for the analysis of radio signals intercepted by various Naval vessels at sea.
