Oscilloscope News

28 July 2015 – Teledyne LeCroy introduced two new trigger and decode options for the WaveSurfer 3000 oscilloscope: CAN FD and FlexRay. The addition of CAN FD and FlexRay trigger and decode capabilities to the WaveSurfer 3000 protocol analyzer capabilities provides all the tools needed to analyze and debug automotive systems using the CAN FD and/or FlexRay serial data communication standards.

The CAN FD and FlexRay trigger can isolate Frame IDs, specific data packets, remote frames and error frames. The decodes use a color coded overlay that clearly identifies different parts of the data being captured, allowing the user to quickly identify different parts of the CAN FD and FlexRay data such as Frame IDs, status bits, and message data.

What is CAN Flexible Data (FD) Rate?

CAN FD is the next generation of the popular CAN standard. As CAN has reached the bandwidth limits of what it can transmit, CAN FD enables higher bit rates and longer data payloads. CAN FD goes beyond the 1 Mb/s limit of classic CAN and will transmit data at up to 10 Mb/s. CAN FD data payloads may now consist of 64 bytes per frame as opposed to the 8 byte per frame limit of classic CAN.

What is FlexRay?

FlexRay is an automotive communication standard that was first used in vehicles in 2006. FlexRay supports data rates up to 10 Mb/s, static and dynamic transmission, synchronous and asynchronous message protocols and has a time triggered deterministic architecture. Additionally, FlexRay can have two independent channels for data communications which allows for redundancy and faul-tolerance.

Pricing

The WS3K-CAN FDbus TD and WS3K-FlexRaybus TD packages for the WaveSurfer 3000 are both priced at $990.
