User Manual
Hardware version
CANBench Duo v1.2 — Schematic-stage refresh of the V1.1 fabricated prototype. V1.2 is electrically identical to V1.1 and carries the InvenTree-canonical component metadata; no V1.2 boards exist yet — testing and bring-up reference the V1.1 hardware.
Other versions: v1.1 — fabricated prototype (current)
Operator-facing manual for the CANBench Duo: bench setup, spectrum-analyser configuration, measurement workflow, status-LED interpretation, common pitfalls, and how to read the results. Pick the page you need.
| Page | What's on it |
|---|---|
| Quick Start | Six-step bench setup — connect supply, connect DUT, terminate unused ports, power on, sweep |
| Spectrum-Analyser Setup | Configuration parameters that work with any analyser; recommended settings for tinySA ULTRA |
| Measurement Procedure | Sweep workflow — analyser noise-floor check, baseline (LISN powered, DUT off), DUT measurement, optional CAN common-mode tap |
| Status LED | What each colour means, what to do, and the troubleshooting flow |
| Common Pitfalls | Mistakes that produce wrong readings and how to avoid them |
| Interpreting Results | LISN+ / LISN− symmetry comparison; CM / DM separation via CANBench TrueZ |
