SigDigger is a powerful DSP-based graphical application for analyzing radio frequency spectrums in real time and examining offline recorded captures. In TelcoChisel, SigDigger is equipped with multi-format audio and digital demodulators (ASK, FSK, PSK, GFSK) and automatic burst detection for reverse-engineering wireless telecommunication protocols.
Key Capabilities
- Automatic Burst & Preamble Detection: Identify transient wireless packet bursts and extract their precise duration and modulation type.
- Constellation Diagrams & Phase Space Analysis: Real-time IQ constellation display for evaluating signal-to-noise ratios and modulation quality.
- Built-in Channel Decoders: Decodes FSK, PSK, and GFSK streams into ASCII / Hex payloads on the fly.
