Inspectrum: Open-Source Signal Analysis Tool
Analyze captured signals from software-defined radios with Inspectrum, a free and open-source tool decoding common signal types like FM radio and displaying spectra and waterfall plots.
What is Inspectrum?
Inspectrum is an open-source program used for signal analysis of captured data, primarily from software-defined radios (SDRs). It has a graphical user interface that allows you to visualize, process, and analyze signals in various ways.
Some of the key features of Inspectrum include:
- Decoding analog signals like FM radio, AM radio, and morse code
- Visualizing signals in a spectrum plot or waterfall display
- Measuring signal parameters like frequency, bandwidth, power, modulation
- Applying filters, transforms, and other digital signal processing functions
- Recording and replaying IQ signal data
- Supporting common SDR hardware like RTL-SDR, Airspy, HackRF
Inspectrum runs on Windows, Linux, and macOS. It can open files in common formats like WAV and RF64. The visualization capabilities, combined with the wide range of built-in decoders and signal processing blocks, make Inspectrum a versatile tool for electronics hobbyists, ham radio operators, engineers, and anyone interested in exploring and understanding radio signals.
