R&S and Rosenberger Verify Automotive Ethernet Speed as per the OPEN Alliance TC9 Specification

Test and measurement specialist Rohde & Schwarz, and connector / cable assembly manufacturer Rosenberger have successfully demonstrated compliance testing for MultiGBASE-T1 supporting 2.5/5/10GBASE-T1 automotive Ethernet speeds, based on the OPEN Alliance TC9 working group test specification. This development enables vehicle manufacturers and component suppliers to have confidence in the performance of future, high-speed in-vehicle networks.

Automotive applications such as ADAS are driving in-vehicle network speeds higher, bringing a challenge to car manufacturers and component suppliers to ensure correct performance of the communication channel and avoid EMI issues. The TC9 group of the OPEN Alliance recently released the first version of a specification for testing components, link segments, and the entire Ethernet channel for fully-shielded 1000BASE-T1 and 2.5/5/10GBASE-T1. The specification defines various RF performance parameters to be tested, for example, insertion loss, return loss, and cross-talk. This also includes requirements on the measurement fixtures, where Rosenberger offers a complete portfolio for a large variety of connector types – all designed and fully verified according to TC9.

During the successful demonstration, Rosenberger provided a fully-shielded H-MTD cable assembly and a pair of matching measurement adapters 02K3E6-S00 with Rohde & Schwarz supplying the R&S ZNB8 4-port vector network analyzer. The performance of all individual components as well as the whole link segment was tested against the new TC9 specification and verified as compliant.

Rohde & Schwarz is supporting Rosenberger, one of the leading cable and connector manufacturers, to verify their products against the new release of the TC9 test specification that includes MultiGBASE-T1 automotive Ethernet speeds with the R&S ZNB8 vector network analyzer.

Rosenberger’s Test & Measurement division supported the development of the Rosenberger H-MTD interface with necessary measurement fixtures and accessories, which allows them not only to deliver the highest quality products but also to accurately verify the electrical properties of every single component. The customers will benefit from the most innovative and flexible single pair system today, which is also expected to be a global standard for automotive high-speed data transmission. They are pleased to work with Rohde & Schwarz measurement instruments and appreciate their support to drive innovation with and for the customers.
