MSO5000HD-ARINC429

MSO5000HD-ARINC429 – ARINC 429 Protocol Decode Option

✈️ Decode Avionics Data with Precision on the MSO5000HD

The UNI-T MSO5000HD Series is a high-performance mixed-signal oscilloscope designed for aerospace, defense, and embedded systems development. With 12-bit vertical resolution, up to 1 GHz bandwidth, and deep memory, it provides the ideal platform for decoding complex time-sensitive buses. The MSO5000HD-ARINC429 unlocks full decode and trigger support for ARINC 429, the dominant data bus standard used in commercial aircraft for flight control, navigation, and system coordination.

ARINC 429 is a unidirectional, point-to-point bus that transmits 32-bit words using a self-clocking format. This decode option helps engineers decode, trigger, and analyze ARINC frames directly within the oscilloscope, dramatically reducing time-to-diagnosis.

🔍 Key Capabilities

• Decode ARINC 429 32-bit words in real time

• View label, SDI, data, and parity fields with full interpretation

• Trigger on label value, SDI, parity error, or user-defined data content

• Scroll through long captures with the event table view

• Identify missing or repeated words, signal glitches, or protocol anomalies

• Correlate analog faults (e.g., level distortion, reflections) with digital decoding

🧠 Benefits of MSO5000HD-ARINC429

• Flight-Grade Troubleshooting Tools
  Quickly isolate issues in flight control systems, navigation modules, or avionics monitoring hardware.

• Real-Time Decoding on a Scope
  Avoid using standalone protocol analyzers—analyze ARINC 429 alongside analog signal integrity in one instrument.

• Confidence in Certification Readiness
  Validate message timing, format, and physical integrity for DO-178/DO-254 compliant systems.

🛠️ Ideal Applications

• Commercial and regional aircraft avionics testing

• Flight data acquisition system development

• Flight control and navigation system integration

• Aerospace R&D labs and manufacturing QA

• Training environments for avionics systems
