MSO5000HD-ARINC429 Aerospace ARINC429 Serial Bus Trigger and Analysis
Overview
The MSO5000HD-ARINC429 adds ARINC 429 protocol triggering, decoding, and search to your MSO5000HD Series oscilloscope — the dominant commercial avionics bus for flight management, navigation, and aircraft systems.
A unidirectional bus at 12.5 or 100 kbit/s. Decode reads label numbers, SDI, data values, and SSM directly from the oscilloscope. The option is enabled by a software license keyed to the oscilloscope's serial number and is permanent for the life of the instrument.
Key Features
- ARINC 429 Triggering — Trigger on label numbers, SDI, data content, SSM, or parity errors.
- 32-Bit Word Decoding — Decoded words with label, SDI, data, SSM, and parity fields clearly identified.
- BNR and BCD Interpretation — Automatically interprets Binary and BCD data formats per ARINC 429 spec.
- Gap/Timing Verification — Measures inter-word gaps and bit timing to identify specification violations.
- Lifetime License Activation — activate once, owned for the life of the instrument. No subscriptions, no renewals, no maintenance fees.
When You Need This Option
The option fits the following workflows:
- LRU Integration — Decode incoming ARINC 429 to verify altitude, airspeed, heading labels have correct values at expected rates.
- Transmitter Qualification — Overlay protocol decode with analog analysis to correlate data errors with signal characteristics.
Compatibility
This option is compatible with all MSO5000HD Series oscilloscopes: MSO5034HD (350 MHz), MSO5054HD (500 MHz), and MSO5104HD (1 GHz). The same capability is offered on other UNI-T oscilloscope families: MSO3000HD, MSO3000X.
Frequently Asked Questions
Should I buy this individually or get a bundle?
If you only need ARINC 429, the individual license covers exactly that protocol. The BND bundle includes every protocol in the series.
How is this option activated?
The option is enabled by a software license keyed to the oscilloscope's serial number. After purchase, the license is registered on the UNI-T website to generate the license file, which is then loaded onto the instrument from a USB drive through the option-install menu. Refer to the oscilloscope's user manual for the step-by-step procedure.
Is the license permanent, or does it require renewal?
The license is permanent — a one-time purchase that stays active for the life of the instrument. No subscriptions, no annual renewals, and no expiration.
