MSO3000HD-ARINC429

MSO3000HD-ARINC429 – ARINC 429 Protocol Decode Option

🛫 Decode Aircraft Data Bus Communications with Clarity and Confidence

The MSO3000HD-ARINC429 unlock adds triggering and decoding support for the ARINC 429 protocol on your UNI-T MSO3000HD Series oscilloscope. ARINC 429 is the most widely adopted unidirectional data bus in commercial aviation—used to transmit status and sensor information between avionics systems, navigation equipment, and flight control units.

With this unlock, you can capture and decode ARINC labels, SDI bits, data words, and parity—all directly from the waveform display, enabling fast and effective validation of airborne communication systems.

✅ Protocols Included by Default (No License Required)

All MSO3000HD scopes include decoding for:

• RS-232 / UART

• I²C

• SPI

🧩 ARINC 429 decoding requires the MSO3000HD-ARINC429 unlock.

🔓 What You Unlock with MSO3000HD-ARINC429

🧠 Real-World Use Cases

✅ Flight Data Monitoring

Decode heading, attitude, or altitude messages sent from air data computers to display systems. Use label filtering to isolate specific navigation parameters.

✅ Avionics Module Validation

Validate correct ARINC transmission from flight management systems (FMS) to autopilot or navigation units. Confirm that SDI and parity bits match expected configurations.

✅ EMI & Signal Integrity Debug

Combine analog waveform capture with ARINC decoding to analyze noise-induced corruption, voltage thresholds, or driver issues.

✅ Integration with MIL-STD-1553

When used alongside the MSO3000HD-MIL1553 option, test systems bridging commercial and military bus standards.
