A Technique to Measure Oscillator Sensitivity.
Abstract
A study of oscillator sensitivity measurement employing a small anechoic chamber is described. Sensitivity is measured in a small (0.91 cu m) chamber suitable for production-line fuze testing. Since the measurement is absolute, no reference is necessary to a pole test facility, as previous test chambers required. The sensitivity measurement technique replaces the pole test as the standard measurement technique and can be performed in small or large anechoic chambers. An error analysis is included, and the estimated measurement error in the small chamber is 10.4 percent. A shortened procedure is described which permits 100-percent production-line testing for fuze sensitivity and radiated power. Admittance data, radiation patterns, and gain data for standard loop antennas used in calibration are also presented. (Author)
