Test on Model LD-3 Combined Heterodyne Frequency Meter and Crystal Controlled Calibrator

Abstract

The equipment was given an inspection of mechanical construction and wiring. Its operation was observed as to crystal frequency, multi-vibrator control, frequency stability of heterodyne oscillator with time of operation, with tilting, with change of tubes and with line voltage change.
