Accelerate debugging of automotive serial buses

Keywords:oscilloscopes? debug? automotive serial buses?

The main reason engineers use oscilloscopes to debug and characterise automotive serial buses, such as CAN, LIN, and FlexRay, is because of an oscilloscope's inherent ability to characterise the analogue quality of these signals. Performing analogue characterisation using an oscilloscope is often referred to as "physical layer" measurements. Serial bus protocol analysers are optimised at performing measurements at the "application layer". Instruments such as these are focused on providing trace flow of data at a higher abstraction levelbut at the cost of providing little or no physical layer measurement capability. A scope is not a replacement for a serial bus protocol analyser, but neither is a serial bus protocol analyser a replacement for a scope. Engineers working on automotive serial bus applications typically have both.
