Oscilloscope News

03 August 2015 – Teledyne LeCroy Teledyne LeCroy CAN FD announced the addition of Symbolic (Application) layer analysis capabilities to their CAN and CAN FD serial trigger, decode, measurement, and graphing solutions. Teledyne LeCroy is the only provider of CAN FD measurement and graphing capabilities, and was the first to provide a trigger and decode solution for CAN FD. The new CAN and CAN FD Symbolic analysis packages allow a user-defined .dbc file to be used for Symbolic triggering, decoding, measurements, and graphing of a CAN or CAN FD bus.

This creates a more user-friendly environment for CAN developers to work in and removes the need for a manual lookup or conversion from the typical hexadecimal or binary format. All Teledyne LeCroy CAN FD trigger and decode packages support both ISO and non-ISO frames per the ISO 11898-1 standard.

A Unique Combination of CAN and CAN FD Analysis Capabilities

The ability to perform analysis directly on the Symbolic layer will greatly increase efficiency when working with Teledyne LeCroy's powerful CAN toolset. When debugging using the oscilloscope to trigger on the Symbolic layer, it is simple to isolate a particular troublesome sequence of events by triggering on a specific message or range of values for a given message. The CAN and CAN FD decoders create an intuitive color-coded overlay directly on top of the physical layer waveform making it easy to quickly identify the different sections of the frame and rapidly flag any errors. Teledyne LeCroy offers the unique ability to take CAN and CAN FD analysis to the next level by using the .dbc file to extract the encoded values to perform precise timing measurements which correlate to specific occurrences on the bus. Furthermore, these extracted values can be plotted to provide a visual representation of how behavior is changing over time. The combination of these tools provide unprecedented insight in to CAN systems, correlating physical layer signals and protocol layer data on a single display while also measuring and plotting bus performance.

Along with having the best method of displaying decoded data, Teledyne LeCroy offers the ability to decode four busses simultaneously. These four busses can be a combination of any protocols, including CAN FD and classic CAN at the same time. Decoded data can also be seen in an interactive table. Entries in this table can be selected and automatically zoomed, preventing the need to scroll through long records. A search function is built in to the zoom trace to quickly locate a specific Frame ID or data message.

Pricing and Availability

CAN TDM SYMBOLIC and CAN FD TDM SYMBOLIC are available on a wide variety of Teledyne LeCroy oscilloscopes. They have a US List price of $4,600 and $5,400 respectively. Teledyne LeCroy oscilloscope users who already have CAN or CAN FD Trigger and Decode can upgrade their system to CAN or CAN FD TDM SYMBOLIC at a US list price of $800.
