CAN, LIN, FlexRay, and CAN-FD Serial Buses

Keysight Technologies, Inc. oscilloscope automotive options help electronic system designers test and debug the physical layer of automotive serial buses faster. CAN, LIN, FlexRay, and CAN-FD serial buses are the backbone for communication among many separate controllers, sensors, actuators, and ECUs located throughout automotive and industrial designs. These serial bus interfaces provide content rich points for debug and test. However, since these protocols transfer bits serially, using a traditional oscilloscope has limitations. Manually converting captured 1s and 0s to protocol requires significant effort, cannot be done in real-time, and includes potential for human error. Also, traditional oscilloscope triggers are not sufficient for specifying protocol-level conditions.

Extend your oscilloscope capability with Keysight’s N8803C CAN, LIN, FlexRay, and CAN-FD protocol triggering and decode application. This software makes it easy to debug and test designs that include these buses using your Infiniium oscilloscope.

  • Set up your oscilloscope to show CAN(FD), LIN, or FlexRay protocol decode in less than 30 seconds
  • Get access to a rich set of integrated protocol-level software triggers
  • Save time and eliminate errors by viewing packets at the protocol level
  • Use time-correlated views to quickly troubleshoot serial protocol problems back to their timing or signal integrity root cause
  • With the CAN-dbc symbolic trigger and decode capability, engineers can now test the physical layer of this differential bus at a higher abstraction level

CAN(FD), LIN, and FlexRay Setup and Protocol Triggering

Get access to a rich set of integrated software protocol-level triggers. The application includes a suite of configurable protocol-level trigger conditions specific to CAN, LIN, FlexRay, and CAN-FD. When serial triggering is selected, the application uses software-based triggering or hardware-based serial triggering . With protocol triggering, the oscilloscope takes signals acquired using either a scope or digital channels and reconstructs protocol frames after each acquisition. It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.

CAN and CAN FD Protocol Decode

Quickly move between physical and CAN-FD protocol layer information using the time-correlated tracing marker. Display protocol content using embedded decode in the waveform area or, see protocol events in a compact listing format. Along with CAN interface innovation, CAN-FD will replace legacy CAN bus line. With N8803C protocol decoder, up to 10 Mbps CAN-FD signals also can be decoded with time-correlated tracking marker.

Import industry-standard .dbc files for symbolic triggering and decode. Message and signal values are displayed on the listing and in the waveform in symbolic format, making it easier to understand the oscilloscope capture.

CAN-FD (Flexible Data-rate) Protocol Decode

CAN-FD protocol decode supports the new CAN (ISO 11898-1) specification, so that it will decode up to 10 Mbps FD data rate, while supporting standard CAN data rate for control part. FD data rate support from 1 Mbps and Infiniium S-Series supports hardware-based serial triggering on CAN-FD signals so you can get the packet you want to see. This trigger supports frame, and bit-specific options such as BRS, CRC ESI, and errors.

FlexRay and LIN Protocol Decode

Quickly move between FlexRay physical and protocol layer information using the time-correlated tracing marker. Display protocol content using embedded decode in the waveform area, or see protocol events in a compact listing format. Minor tick marks indicate clock transitions. Major tick marks indicate segments of the serial packets.

If you need to connect to DB9-SubD connectors on your differential CAN and/or FlexRay bus, Keysight also offers the CAN/FlexRay DB9 probe head (part number 0960-2926). This differential probe head is compatible with both the N2791A and N2818A differential active probes and allows you to easily connect to your CAN and/or FlexRay differential bus. For more information about Keysight’s probing solutions, refer to the Infiniium Series Oscilloscope Probes and Accessories data sheet (publication number 5968-7141EN).
