The oscilloscope is the primary measurement tool used today to test and debug the physical layer of automotive serial buses, including CAN (also CAN-dbc symbolic decoding), CAN FD, LIN, SENT, FlexRay, BroadR-Reach, and MOST. The electrical environment in automobiles is naturally harsh with lots of noise and often unexpected transients. The core competence of an oscilloscope is that it can capture and show you details of those infrequent automotive transients and noise that could be producing bus errors. Keysight offers a broad range of automotive serial bus applications in both the InfiniiVision and Infiniium oscilloscope families, including protocol decode/trigger, eye-diagram mask testing, and physical layer compliance test packages. You can find more information in the links below.
The application notes featured here will provide an overview of all of the automotive serial bus protocol decode and trigger options available for the InfiniiVision family of oscilloscopes and includes the following protocols CAN, CAN-dbc, CAN FD, LIN, FlexRay and SENT.
