Abstract

Most of the noise instruments can only give a noise figure or equivalent input noise at several frequency points or several fixed frequency bands. An automated system for measuring electronic noise and performance factors is presented. The system gives not only the power spectral density of equivalent input noise voltage and current, but also other performance factors. High accuracy of noise measurements is obtained by using a low-noise amplifier and using scanning CW signals to measure transfer functions. The noise measurement and processed data are automatically produced by a personal computer
