Product Overview

Product Overview

REI SignalLab 2.1 is a browser-based laboratory suite for signal synthesis, transformation, filtering, spectral analysis, visualization, reproducible signal-flow experiments, and industrial machinery vibration analysis. It combines a React interface with a FastAPI/SciPy computation service.

🌟 Six Principal Workspaces

1. Dual Oscilloscope & Spectrum Analyzer: CRT 60 FPS hardware renderer, FFT spectral analysis, and studio telemetry (THD, SNR, SINAD, SFDR, ENOB).
2. Signal Flow Studio (.rei-signal 2.1): Visual drag-and-drop node graph canvas backed by Kahn's topological execution engine.
3. REI Vibration Analysis Workbench: Rotating machinery condition monitoring, single-plane complex vector rotor balancing, bearing defect frequencies (BPFO, BPFI, BSF, FTF), 1X-10X harmonic orders, and rule-based fault classification.
4. Experimental Python Lab: Python signal processing sandbox with stdout and Matplotlib figure capture.
5. 2D Waterfall Spectrogram: Real-time time-frequency spectrogram heatmap.
6. S-Expression DSP Kernel: Lisp macro kernel executing SIMD and quantized vector transformations.

🔒 Data Trust Boundary Separation

SignalLab explicitly identifies where results were computed:

• [ API VERIFIED ] (Green): Verified FastAPI/SciPy backend computed metrics.
• [ LOCAL BROWSER DSP ] (Cyan): Browser-side JS/WebAudio computed metrics.
• [ DEMO MODE ] (Yellow/Red Warning): Simulated demonstration data — not for instrument measurement.
