The Essential Noise Figure Measurement Guide - Measuring Noise Figure with Signal Analyzers - Part 1

White Papers

You need to optimize your device’s performance, however noise added by a system’s components often obscures the very weak signals that modern receiving systems must process. Having the right measurement tools is important in order to optimize performance and eliminate second guessing of your results.

Sensitivity, bit error ratio (BER), and most importantly, noise figure are system parameters that characterize the ability for a receiving system to process low-level signals. In the first part of this two-part series on noise-figure, you will gain a solid foundation on the fundamentals of noise figure and the most popular method used to characterize it for your device. In the second part of this series, you’ll learn how to make a noise figure measurement on your device under test (DUT) using a signal analyzer, noise source, and noise figure application.
