Try it
Prerequisites
- cmake >= 3.1
- fftw 3.x
- liquid-dsp >= v1.3.0
- pkg-config
- qt5
- libsigmf (optional, for SigMF support)
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:
-
*.sigmf-meta, *.sigmf-data- SigMF recordings -
*.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) -
*.f32- Real 32-bit floating point samples -
*.s16- Real 16-bit signed integer samples -
*.s8- Real 8-bit signed integer samples -
*.u8- Real 8-bit unsigned integer samples
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
