inspectrum

inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.

Try it

Prerequisites

cmake
fftw 3.x
liquid-dsp >= v1.3.0
pkg-config
qt5

Build instructions

Build instructions can be found here: https://github.com/miek/inspectrum/wiki/Build

Run

./inspectrum [filename]

Input

inspectrum supports the following file types:

*.cf32, *.cfile - Complex 32-bit floating point samples (GNURadio, osmocom_fft)
*.cs16 - Complex 16-bit signed integer samples (BladeRF)
*.cs8 - Complex 8-bit signed integer samples (HackRF)
*.cu8 - Complex 8-bit unsigned integer samples (RTL-SDR)

If an unknown file extension is loaded, inspectrum will default to *.cf32.

Features

Large (100GB+) file support
Spectrogram with zoom/pan
Plots of amplitude, frequency, phase and IQ samples
Cursors for measuring period, symbol rate and extracting symbols
Export of selected time period, filtered samples and demodulated data
