Lesson 1 - Introduction - Debugging Automotive & Electronic Signals using Oscilloscopes


Quickly trigger, decode, and create-eye diagrams for automotive serial buses such as CAN, CAN FD, LIN, SENT, and more!

An oscilloscope’s inherent ability to characterize the analog quality of automotive serial buses is why engineers often use oscilloscopes to debug and characterize these signals. Performing analog characterization using an oscilloscope is often referred to as "physical layer" measurements.  An eye-diagram mask test is the single most important measurement that can be performed with an oscilloscope to evaluate the overall quality of a system's physical layer in one composite measurement. However, creating a proper eye-diagram measurement on an oscilloscope’s display requires much more than just triggering on rising and falling edges.

Keysight’s InfiniiVision X-Series oscilloscopes can trigger, decode, and perform eye-diagram mask test measurements on serial bus standards often found in automotive applications such as CAN, CAN FD, LIN, SENT, and more.  This course will explore many of the most popular automotive serial bus protocol trigger & decode capabilities and advanced analysis features enabled on the InfiniiVision X-Series oscilloscopes.
