Unlike basic protocol analyzers, oscilloscopes equipped with protocol decoding can be used to see both the decoded bus traffic, as well as signal quality, making scopes the best choice for troubleshooting. This application note explains the physical layer basics of common automotive buses –CAN, LIN, and FlexRay – to enable you to troubleshoot bus problems or system issues. Learn how to set up and interpret the results when using automated decoding, triggering, and search on an oscilloscope equipped with automotive bus analysis capability.
