MSO3000X-ARINC429

MSO3000X-ARINC429 – ARINC 429 Protocol Decode Option

🛫 Decode Critical Avionics Data Bus Communications

The MSO3000X-ARINC429 unlock enables full triggering and decoding for the ARINC 429 protocol on your UNI-T MSO3000X Series oscilloscope. Widely adopted in commercial aircraft, ARINC 429 is a unidirectional, point-to-point data bus used to communicate between navigation, flight control, sensor, and display systems.

With this unlock, engineers and technicians can decode 32-bit ARINC words in real time, analyze SDI and SSM fields, and trigger on specific label IDs—giving you a precise view into the flight-critical communication flows that keep aircraft operational and safe.

✅ Standard Protocols Always Included

All MSO3000X models include:

• RS-232 / UART

• I²C

• SPI

🧩 ARINC 429 decoding requires the MSO3000X-ARINC429 unlock.
