Rohde & Schwarz introduces trigger and decode solution for automotive Ethernet


Rohde & Schwarz launched the world’s first triggering and decoding solution for 1000BASE-T1, further extending its leading position in test solutions for automotive. Similar, to the existing 100BASE-T1 or CAN bus analysis and decode capability, OEMs and Tier1 suppliers now can analyse and decode the latest bus speeds at the leading edge of automotive digital design.

The flexibility of Automotive Ethernet makes the simple twisted-pair network technology ideal for an ever-increasing range of in-vehicle networks. To verify, commission and troubleshoot designs based on an Automotive Ethernet communication link, it is important to have an instrument capable of not only measuring and verifying compliance to the standards but also decoding the messages and reliably triggering on them.

The new K58 option for the R&S RTO and R&S RTP oscilloscopes provides a fast and efficient means to perform this analysis. Users can debug and verify their in-vehicle networks and ECU implementations. The decoded data can be displayed, in a table as well as in the usual honeycomb diagram. The important parameters such as Idle, MAC or error frames are, easily identifiable via defined colour codes. With the R&S RT-ZF7 probing fixtures, both the forward and reverse data streams can be decoded, simultaneously. Additionally, the oscilloscopes support simultaneous decoding of up to four serial buses.

Comprehensive search functions simplify the analysis of long signal sequences. Specific message types, content and errors can be quickly isolated. All detected events are shown, in a table with timestamps. The user can then examine the individual events in a zoom window with the proper timing correlation and navigate between the events.

Combing the new trigger & decode functionality with the unique K35 bus measurements option, in-depth measurements like the error frame rate and several consecutive frame errors, help determine the stability of the link quickly. The error rates, as well as frame timing, are measured simultaneously, both very important for automotive applications such as for autonomous driving.
