Debugging Automotive Differential CAN Buses Faster
Application Notes
The primary measurement tool used today to test and debug the physical layer of the CAN differential serial bus in automotive systems is an oscilloscope. 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 CAN bus errors.
