Inspectrum
Features
- IQ Sample File Viewers - Loads complex and real IQ sample files and shows their frequency-domain representation for visual inspection.
- Plugin-Based Format Readers - Uses a plugin registry of format-specific readers for SigMF, GNU Radio, BladeRF, HackRF, and RTL-SDR sample files.
- Memory-Mapped File Access - Maps files into virtual memory to access multi-gigabyte captures without loading them entirely into RAM.
- Spectrogram Generation - Displays a time-frequency heatmap of a captured signal with zoom and pan across the recording.
- SDR Spectrogram Analyzers - Displays a time-frequency heatmap of captured radio signals with zoom, pan, and measurement capabilities.
- SDR Sample Format Loaders - Reads complex and real sample files in common SDR formats including SigMF, GNU Radio, BladeRF, HackRF, and RTL-SDR.
- IQ Sample File Readers - Loads IQ sample files in SigMF, GNU Radio, BladeRF, HackRF, and RTL-SDR formats.
- Tile-Based - Divides the time-frequency display into cached image tiles recomputed only on zoom or pan changes.
- Spectrum Capture and Analysis - Loads an IQ sample file from disk and displays its spectrum for interactive analysis.
- Spectrogram Cursor Measurements - Plot amplitude, frequency, phase, and IQ samples alongside the spectrogram for detailed waveform inspection.
- Spectrogram Zoom Controls - Provides interactive zoom and pan controls for navigating spectrogram time-frequency displays.
- Signal Visualizers - Displays spectrograms with zoom and pan, plus plots of amplitude, frequency, phase, and IQ samples.
- Spectrogram Cursor Measurements - Reads cursor-position values for frequency, time, and amplitude directly from the spectrogram display.
- Large Recording Analyzers - Opens and navigates radio-frequency recordings exceeding 100 gigabytes without excessive memory use.
- Radio Signal Analysis - Displays a spectrogram of recorded SDR data with zoom and pan for detailed inspection of signal content.
- Spectrogram Displays - Displays a time-frequency heatmap of captured radio signals with zoom and pan for detailed inspection.
- Signal Decimation Pipelines - Downsamples raw IQ data on the fly to keep rendering responsive for large files.
- Radio IQ Sample Recorders - Opens and navigates radio-frequency recordings exceeding 100 gigabytes without excessive memory use.
- Large Recording Analyzers - Opens and navigates radio-frequency recordings exceeding 100 gigabytes without excessive memory use.
- Large Recording Navigators - Opens and navigates radio-frequency recordings exceeding 100 gigabytes without excessive memory use.
- Plot Pan and Zoom Controls - Navigates along the time and frequency axes of a spectrogram to examine signal details at different scales.
- Synchronized Multi-Plot Viewports - Links spectrogram, amplitude, frequency, phase, and IQ plots so zooming one updates all others.
- Spectrogram Measurement Cursors - Places measurement cursors on the spectrogram to read time, frequency, and amplitude values.
- Data Export - Saves selected time ranges, filtered samples, or demodulated results to a file for further use.
- Spectrogram Cursor Tools - Places cursors on a spectrogram to read period, symbol rate, and export individual symbols.
- Infrastructure Monitoring - Radio signal analyser.
