The Teledyne LeCroy HDO4K-ARINC429BUS DSYMBOLIC option decodes ARINC 429 serial data into symbolic (Application layer) text directly on the oscilloscope display. The user defined file converts the decoded hex, binary, hexadecimal, or decimal values into a label defined by the ARINC 429 system. The ARINC 429 DSymbolic solution concentrates all user information in one place. Viewing the application layer of ARINC 429 signals on top of the physical layer provides a unique view that bus analyzers cannot. Measurements such as amplitude and rise time help to debug physical layer issues that may not be apparent in a protocol view.

The ARINC 429 Symbolic decode uses color-coded overlays on various sections of the protocol for an easy-to-understand visual display. Depending on the time base or the amount of zoom, the decode information is condensed or expanded to better assist in understanding events during short or long acquisitions. The ARINC 429 Decode and Symbolic solution is the ideal tool for system level protocol debug as well as problem solving for signal quality issues. The ARINC 429 Decode and Symbolic package adds a unique set of tools to an oscilloscope, simplifying how to design and debug ARINC 429 systems. ARINC DSymbolic provides a unique and powerful way to view decoded data. Using a user provided file, the label and equipment ID fields can be displayed to match the user provided file, showing an easier to interpret protocol display. The powerful symbolic decoding of ARINC 429 coverts the data field to match a user specified message. Here the specified converted data is Selected Air Speed = 64.5 Knots.

Turn an oscilloscope into a protocol analyzer with the table display of protocol information. The user can custom configure the Table to display the information they want, and export Table data to an Excel file. Touch the message in the table and automatically zoom for detail. In all cases, the Table never obscures the waveforms. Quickly view valuable information for each ARINC 429 word, such as Label, SDI, Data, SSM, Parity, and symbolic message. Search through a long record of decoded data by entering any of the 28 available search criteria by entering a value, or simply finding the next occurrence. Search can locate up to 14 selectable criteria, or narrow down the search by entering a value.
