The Teledyne LeCroy HDO4K-CAN FDBUS TD provides high performance triggers and transparent color-coded decode overlays, protocol tables, and search capabilities for both CAN and CAN FD. With CAN and CAN FD trigger and decode the oscilloscope becomes the ideal tool for debugging CAN controllers, busses and systems. Identify and isolate specific frames with ID, Remote and Error frame triggering. Decoding CAN signals provides tremendous insight into activity on the bus, and measurement tools enable fast analysis of bus performance.

Decoded protocol information is color-coded to specific portions of the CAN, CAN FD, and ISO CAN FD frame, and displayed directly on top of physical layer signals creating an intuitive and easy-to-understand visual display. The decoded information adjusts as the horizontal scale is changed to always provide the right amount of detail in both short and long acquisitions.

Powerful measurements and sophisticated statistical, graphical, and plotting tools simplify CAN system debugging. Understanding CAN bus problems and performance is quick and easy.

The CAN and CAN FD trigger will isolate Frame IDs, specific data packets, remote frames or error frames. For CAN FD signals, the oscilloscope can trigger on both ISO and non-ISO variants as well as specific frames with the Bit Rate Shift (BRS) bit. Powerful, conditional triggering enables triggering on a range of events such as a series of Frame IDs or data messages.

Importing a .dbc file allows for decoding, triggering, and measurements to be performed directly on the Symbolic (Application) layer, enabling an easier to understand CAN toolset.

CAN and CAN FD specific measurement parameters allow users to quickly and easily characterize a system and make gateway measurements. Measure the time between two messages on the bus or from a CAN message to analog signal. Measurement statistics and histicons provide insight into the range of measurements on the bus. Quickly make CAN timing measurements and monitor system performance with the CAN or CAN FD TDM parameters. Teledyne LeCroy’s statistical measurements with histograms, tracks and trends shows how the bus behaves over time.

Extract data from the CAN and CAN FD message streams and use track functions to graphically plot the data. Measured values are used to convert digital information into an analog waveform for easy comparison to other electrical signals. Information on the steering angle and steering angle rate of change is extracted from the CAN message acquisition, rescaled to decimal values, and plotted as a time-correlated “Track.”

Turn the oscilloscope into a protocol analyzer with the table display of decoded information. Customize the table to show only the data of interest and touch a message in the table to automatically display it on the screen. Export the table for offline analysis. Display decoded values in an easy-to-understand table. Values can be displayed in either hexadecimal or symbolic formats. Filter decoded values to isolate information of interest. Search through long records of decoded CAN data for specific Frame IDs, data values, frame types or status bits. Search through long records of decoded data by entering specific message or frame details.
