USB429 Bus Analyzer 2.0

USB429 Bus Analyzer is a PC application for monitoring, decoding, recording, and stimulating ARINC 429 data through a USB-connected interface. Designed for lab, integration, and flight-line work, it gives engineers clear, real-time visibility into bus activity while providing the tools needed to troubleshoot, validate, and document ARINC 429 systems.

Key capabilities:

• Live monitor and decode of ARINC 429 words, including labels, SDI, SSM, parity, and high/low speed rates (12.5/100 kbps)
• High‑resolution timestamping, bus statistics, and error detection (parity, gaps, noise events)
• Flexible filters, triggers, and searches by label, SDI, value ranges, or bit fields
• Transmit and stimulate functions: build words, schedules, and replay captured traffic
• User‑defined databases/ICDs for label mapping, bit‑field definitions, and engineering units
• Multi‑channel capture with synchronized views and correlation across channels
• Bookmarks, annotations, and event markers for rapid navigation and reporting
• Data export to common formats (e.g., CSV) for analysis and documentation
• Scriptable automation via API or command tools for regression and hardware‑in‑the‑loop workflows
• Intuitive timeline and tabular views suitable for both quick-look checks and deep analysis

Typical uses include system integration testing, fault isolation, avionics upgrades, and acceptance or maintenance checks. The software helps reduce turnaround time by combining reliable capture and decode with powerful filtering, playback, and reporting features. Compatibility and specific feature sets may vary by the USB ARINC 429 interface in use.
