New protocol trigger and decode software simplifies development/troubleshooting of various automotive CAN bus systems
Keysight Technologies has released its first oscilloscope-based automotive protocol trigger/decode system covering CAN XL (Controller Area Network eXtra Long) that enables engineers to verify and debug low-speed automotive serial bus protocols and simplify the development and troubleshooting of systems including CAN/CAN FD (Flexible Data Rate) and CAN XL.
CAN XL is the third-generation CAN standard in development by the CAN in Automation (CiA) group that improves the well-established CAN FD protocol with increased payload data and faster bit rate. The CAN XL data phase speed is specified to reach 10 Mbps or more, depending on the transceiver capabilities and physical layer components. CAN XL has two modes of operation – fast mode and SIC mode (or slow mode).
Keysight’s automotive decoder software triggers and decodes the SIC mode signal in the arbitration phase, as well as the fast mode signal in the data phase, correctly. It also handles the CAN XL protocols implemented with the CAN HS/FD/SIC transceivers.
“In-vehicle networking technologies play a pivotal role in transmitting data fast and reliably from sensors to AI decision making units, as well as in-between safety relevant electronic control units and electronic systems within the car,” said Thomas Goetzl, vice president and general manager for Keysight’s automotive & energy solutions business unit.
