Rohde & Schwarz Introduces the First Trigger and Decode Solution for 1000BASE-T1 Automotive Ethernet

With the new K58 option for its oscilloscopes R&S RTO and R&S RTP, Rohde & Schwarz launched the world’s first triggering and decoding solution for 1000BASE-T1.

Similar to the existing 100BASE-T1 or CAN bus analysis and decode capability, OEMs and Tier1 suppliers now have the possibility to analyze and decode the latest bus speeds at the leading edge of automotive digital design.

Per the company, the Automotive Ethernet makes the twisted-pair network technology ideal for a range of in-vehicle networks. In order to verify, commission, and troubleshoot designs based on an Automotive Ethernet communication link, it is ideal to have an instrument that is 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 provide sutiable 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. Parameters such as Idle, MAC, or error frames are 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 analysis of long signal sequences. Specific message types, content, and errors can be 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 number of consecutive frame errors, helps to determine the stability of the link. More analysis of bus timing, such as the delay between frames or between any trigger event and the subsequent bus frame can be discovered. The error rates as well as frame timing are measured simultaneously, both ideal for automotive applications such as for autonomous driving.

Rohde & Schwarz oscilloscopes decode protocol-specific trigger results, allowing reliable debugging. The capability of combining bus measurements and statistics offers insight into bus capacity, error frame rates, and latency issues. Per the company, this enables development processes and gives engineers confidence in reliable performance of their products. No additional instruments are required.

The R&S RTO-K58 and RTP-K58 trigger and decode test software options for 1000Base-T1 are now available from Rohde & Schwarz.
