An Absolute Measurement Procedure to Determine Oscillator-Detector Sensitivity and Power,

Abstract

A method of measuring the sensitivity and radiated power of oscillator-detector systems without the need for calibration with a pole test is presented. The measurement technique applies to both CW and modulated systems. The basic measuring technique is discussed, and then a rapid testing procedure, which requires chamber precalibration over the desired frequency range, is described. Reference is made to a novel standard loop antenna which has a 50-ohm driving impedance and is used in the measurement procedure. An error analysis is included which can be used to determine the accuracy of this technique. (Author)
