Keysight Technologies Oscilloscope Measurement Tools to Help Debug Automotive Serial Buses Faster Application Note Introduction The primary reason engineers use oscilloscopes to debug and characterize automotive serial buses, such as CAN, CAN FD, LIN, SENT, and FlexRay, is because of an oscilloscope's inherent ability to characterize the analog quality of these signals. Performing analog characterization using an oscilloscope is often referred to as "physical layer" measurements. Serial bus protocol analyzers are optimized at performing measurements at the "application layer". Instruments such as these are focused on providing trace flow of data at a higher abstraction level -- but at the cost of providing little or no physical layer measurement capability. A scope is not a replacement for a serial bus protocol analyzer, but neither is a serial bus protocol analyzer a replacement for a scope. Engineers working on automotive serial bus applications typically have both. Although there are many oscilloscopes on the market today from multiple vendors that offer automotive-focused options, the Keysight Technologies, Inc. InfiniiVision Series oscilloscopes offer some unique measurement capabilities (only available in Keysight scopes) for debugging and characterizing the physical layer of automotive serial buses including:
