What is RF Spectrum Analyzer Software?
RF Spectrum Analysis Software is a specialized tool used to analyze and visualize radio frequency signals across the RF spectrum.
It processes data from various RF sources, such as spectrum analyzers, receivers and software-defined radios (SDRs). The software then displays information about the frequency, amplitude, and phase of signals.
This software is essential for engineers, technicians, and researchers working in telecommunications, broadcasting, military, and other fields that rely on wireless communication.
In this post, we present a list of some of the best free RF spectrum analyzer software, along with unique features for each.
