STEPPED_FREQUENCY_EXCITER

Published:2009/7/21 7:47:00 Author:Jessie | From:SeekIC

Provides crystal-controlled output frequency in 100-kc steps at 1-sec intervals from 31.05 to 54.95 Mc, with each step an odd multiple of 50 kc. Used to control pulse transmitter and receiver at widely separated locations, for observation of mutual propagation conditions between the two points. Frequency control of r-f oscillator is obtained by mixing sample r-f signal with 1-Mc reference and comparing components of product with 50-kc pulse spectrum supplied by pulse generator V6B.-Frequency Stepper for Radio Propagation Tests, Electronics, 32:4, p 44-46.
