SigDigger is a Qt-based digital signal analyzer and graphical front end for Suscan that’s designed to help investigate and extract information from unknown radio signals.
It works with a wide range of software defined radio hardware through SoapySDR and focuses on practical signal analysis tasks such as spectrum inspection, channel analysis, demodulation, recording, and reverse engineering of bursty or difficult transmissions.
This is free and open source software.
Key Features
- Supports a wide range of SDR devices through SoapySDR.
- Offers both real-time and replay analysis modes.
- Provides OpenGL-enhanced spectrum and waterfall displays.
- Includes analog audio playback for AM, FM, LSB, and USB signals.
- Supports baseband recording for full-spectrum and per-channel captures.
- Offers waveform inspection with burst detection and limited off-line demodulation tools.
- Includes interactive panoramic spectrum browsing and bandplan information.
- Supports ASK, FSK, and PSK inspection, along with symbol recording and visualization.
- Provides blind parameter estimation, Doppler analysis, and transition analysis tools.
- Includes analog TV demodulation and network broadcast of demodulated channel data.
- Cross-platform support – runs under Linux, macOS, and Windows.
