R&S scopes support analysis of high-speed CAN FD interface protocol

Dec. 15, 2014

Rohde & Schwarz announced that with its R&S RTE and R&S RTO oscilloscopes, the company offers analysis solutions for the CAN flexible data (CAN FD) interface protocol. CAN FD is seeing increased use in automotive and industry applications due to rising data rate requirements.

Introduced in 2012, the CAN FD serial bus protocol with a maximum data rate of up to 15 Mb/s boosts controller area network (CAN) performance., thereby benefiting, for example, the automotive industry in developing modern motor management solutions.

The R&S RTx-K9 option now enables R&S RTE and R&S RTO oscilloscope users to analyze interfaces of this type. Hardware-based decoding makes finding errors with the oscilloscopes fast, which accelerates the design verification and commissioning processes for chipsets with CAN FD interfaces.

Users can trigger directly to telegram start, stop, and data values and use the high-performance search and navigation function to find relevant events in the CAN FD bus protocol. Decoded telegrams are displayed as color-coded bus signals in a waveform diagram or as a table. The new software option from Rohde & Schwarz also supports industry standard CAN-dbc files for describing bus configurations. The R&S RTE and R&S RTO allow users to simultaneously decode up to four serial buses from analog or logic signals.

Rohde & Schwarz offers a number of additional product solutions for its oscilloscopes that are tailored to the automotive industry. They include the CAN/LIN and FlexRay triggering and decoding options for debugging during component development and integration. There is also an option available for verifying BroadR-Reach compliance—a technology now being increasing used for networking various in-vehicle systems.
