Teledyne LeCroy ARINC 429 decode and symbolic solution is a 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 the HDO4000 oscilloscope, simplifying how users design and debug ARINC 429 systems. Colour-coded overlays on various sections of the protocol make 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 package 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. Information is concentrated in one place. Viewing the application layer of ARINC 429 signals on top of the physical layer provides a unique view that bus analysers cannot. Measurements such as amplitude and rise time help to debug physical layer issues that may not be apparent in a protocol view. Label and equipment ID fields can be displayed to match user-provided files, showing an easier way to interpret protocol display.
