- Tektronix has launched a solution for decoding the CAN XL (Controller Area Network Extended Length) protocol.
- This protocol decoder, which runs on Tektronix MSO Series 4, 5 and 6 oscilloscopes, supports CAN XL, the third generation of the CAN communication protocol.
With the ability to decode signals representing data packets transmitted using CAN XL frames in a CAN network, the Tektronix CAN XL protocol decoder runs on today’s 4, 5, 6 Series MSO Oscilloscopes and also offers features such as error detection, analysis and debugging of timing and protocol headers.
CAN XL is the latest generation in the CAN (Controller Area Network) protocol family, developed and standardized by the CAN in Automation (CiA) consortium, of which Tektronix is a member. The new standard allows mixed message types – Ethernet tunneling and traditional signal-based CAN – at faster data rates of 20 Mb/s. These transmission types and rates are required to handle increasing amounts of sensor data, enabling advanced driver assistance system (ADAS) features and paving the way for the Software Defined Vehicle (SDV).
Support for the new CAN XL frame structure is included in the Automotive Bus Decode and Analysis (SRAUTO) software package available for Tektronix 4, 5 and 6 Series MSO oscilloscopes. Customers who already have the SRAUTO package can update it adding the ability to decode CAN XL data packets, not only displaying normal data, but clearly indicating CRC errors, missing ACKs, and XL form errors.
The package includes the ability to trigger on CAN XL Start of Frame and End of Frame, as well as search through acquired signals to find specific CAN XL packets. The package also decodes CAN and CAN FD decoding, supporting mixed mode networks. The presentation of decoded packets is possible in both a waveform view and in a formatted, timestamped table.
The Tektronix CAN XL protocol decoder is now available globally, as part of the SRAUTO option, or as a firmware update for instruments with an active license for the SRAUTO software package. It is also available as part of application software bundles for automotive and serial bus support.
