Basics of spectrum analyzer measurements

Master key measurements with our step-by-step guides

The spectrum analyzer is an essential instrument on an electronics bench. It detects signals in a selected spectrum range and represents them in a graphical display as magnitude vs. frequency. This allows users to characterize electronic devices by identifying frequency peaks, signal harmonics, interference patterns, etc.

The articles on this page walk you through the fundamentals of spectrum analyzer measurements, with topics covering:

Basic spectrum analyzer operation
RF measurements and applications
