Noise Figure Measurement System Y-Factor Method
Overview
The noise figure of a device provides a quantifiable measure of the noise that a Device Under Test (DUT) adds to a signal as that signal passes through it. There are various methods to perform noise figure measurement, including the direct method, Y-factor method, and the cold method.
The developed system is designed to make a noise figure measurement by using the Y-factor method and the NI PXI platform based Vector Signal Analyzer (VSA) to minimize the problem of noise generated in receiving systems.
The noise calculation of RF and microwave devices is done by using the Noise Figure Measurement Toolkit, which includes a DUT control program along with automated report generation.
