The Teledyne Lecroy WS4KHD-AUTO TD Automotive bundle offers the capabilities for CANbus TD, LINbus TD, and FlexRaybus TD, and is for use with the WaveSurfer 4000HD Oscilloscope series.

The trigger permits a conditional setup for the DATA condition. This is especially useful in situations where abnormal events should be monitored, such as when a CAN node broadcasts a low or high engine RPM or coolant pressure.

CAN remains the most used vehicle serial data bus. Many vehicle bus software architectures are very message dense, and data for a single message is spread across multiple data bytes. The hexadecimal and measurement toolsets permit isolation of specific bit-level data patterns in one or more data bytes, e.g., data location in bits 17-28 in data bytes 3, 4, and 5. This provides significant advantages in isolating the exact information or behavior needed. Symbolic message/signal setup is even simpler.

A transparent overlay with color-coding for specific portions of each protocol and the entire message frame makes it easy to understand the serial data information. Unlike other solutions, with protocol decode information away from the signal, our solution correlates the waveform and the protocol decode directly on the display. As the acquisition length is expanded or shortened, the decode overlay will adjust to show just the right amount of information.

Turn the oscilloscope into a protocol analyzer with a tabular display of decoded information. Customize the table to show only the data of interest and touch a message in the table to automatically zoom to it and display it on the screen. Export the table for offline analysis. Up to four different decoded signals of any type may be simultaneously displayed in the table.
