Test and measurement specialist Rohde & Schwarz, together with connector and 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.
Dr. Nik Dimitrakopoulos, Market Segment Manager Automotive at Rohde & Schwarz, stated, “We are very
happy to support 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 our R&S ZNB8 vector network analyzer. This is another example of providing our
customers with confidence in verifying their cables and connectors against very demanding standards and
emphasizes Rohde & Schwarz’s commitment to a safer and connected world.
Hauke Schütt, Executive Vice President Test & Measurement from Rosenberger, adds: “Our Test &
Measurement division supported the development of the Rosenberger H-MTD® interface with necessary
measurement fixtures and accessories, which allows us not only to deliver highest quality products, but also
to accurately verify the electrical properties of each single component. Our 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. We are pleased to work with Rohde & Schwarz measurement
instruments, and we appreciate their support in order to drive innovation with and for our customers.”
