With its R&S RTE and R&S RTO oscilloscopes, Rohde & Schwarz is one of the first suppliers to offer analysis solutions for the CAN flexible data (CAN FD) interface protocol. A new option enables design engineers to analyze CAN interfaces that support the high-speed CAN FD bus protocol. These interfaces are 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 Mbps boosts controller area network (CAN) performance. This benefits, 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 and trigger to protocol details. Hardware-based decoding makes finding errors with the oscilloscopes especially fast, which accelerates the design verification and commissioning processes for chipsets with CAN FD interfaces.
Users can trigger directly to telegram start, telegram 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.
