Rohde & Schwarz and Rosenberger verify MultiGBASE-T1 compliance test according to OPEN Alliance TC9 test specification

  • Rohde & Schwarz 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.
  • Vehicle manufacturers and component suppliers will be able to evaluate the performance of future high-speed in-vehicle network.

Automotive applications such as advanced driver assistance systems (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 portfolio for a variety of connector types – all designed and 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 while Rohde & Schwarz supplied 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.

Hauke Schütt, Executive Vice President Test & Measurement from Rosenberger, said : « Our Test & Measurement division supported the development of the Rosenberger H-MTD interface with necessary measurement fixtures and accessories, which allows us to accurately verify the electrical properties of each single component. Our customers will benefit from a single pair system, which is expected to be a global standard for automotive high-speed data transmission.»
