Keysight Technologies has introduced CAN FD (controller area network with flexible data-rate) and SENT (single-edge nibble transmission) triggering and decoding options for its InfiniiVision 4000 X-Series oscilloscopes. The new capabilities improve engineering efficiency in debugging CAN FD and SENT serial buses, used primarily in automotive applications. CAN FD is a serial bus protocol for automotive control and diagnostic applications. SENT is a point-to-point serial bus that interfaces sensors to ECUs.
