Electrical Characteristics of Audio Oscillator in the Model RDJ -1 Pulse Analyzer
Abstract
The audio calibration oscillator of the Model RDJ-1 Pulse Analyzer was checked for frequency stability under conditions of varying temperature and humidity, for accuracy of oscillator dial calibration and harmonic voltage content. The dial drive vernier ratio has been increased to give a finer control in determining pulse repetition frequencies. This higher ratio is more satisfactory that that used in the X-RDJ and RDJ Pulse Analyzers. The results of the tests were considered satisfactory since the equipment met all of the requirements of the specification on the operation of the oscillator. The equipment may be considered acceptable for Naval use in so far as indicated by the tests reported.
