With R&S RTx-K9 option, R&S RTE and R&S RTO oscilloscope users can analyze CAN interfaces that support high-speed CAN FD bus protocol. Hardware-based decoding helps quickly find errors, accelerating design verification and commissioning. Users can trigger directly to telegram start, telegram stop, and data values and use search and navigation function to find relevant events in CAN FD bus protocol. Decoded telegrams are displayed as color-coded bus signals in waveform diagram or as table.
