Rohde & Schwarz and Allion labs collaborate on automotive testing
Partnership provides Automotive Ethernet testing in compliance with the OPEN Alliance TC9 standards for higher data rates.

Rohde & Schwarz Taiwan, a subsidiary of the global technology group, and Allion Labs, a leading professional services group providing certification testing services, have jointly developed test capabilities for Automotive Ethernet Shielded and  Unshielded Twisted Pair (UTP and STP) in compliance with the OPEN Alliance TC9 standards.

Developments in Advanced Driver Assistance Systems (ADAS) and infotainment are driving up automotive data rates. As they grow, it becomes increasingly important to ensure the quality and performance of the cables and components of the communication channel. Ethernet is a key enabler for high data rate applications, as well as for data backbone, connecting different domain controllers. OPEN Alliance, the global standard-setter for Automotive Ethernet, specifies the electrical requirements and test procedures for cables and connectors through the technical committee TC9. These standards ensure compliance with link segment requirements of the IEEE 802.3 Automotive Ethernet at various speed levels up to 10GBASE-T1 and they describe a mandatory test procedure for all cables and  connector manufacturers producing products for Automotive Ethernet.

The combination of the ZNB vector network analyzer from Rohde & Schwarz together with the Allion AET21064 customized cable fixture and a conductive drum provide cable and connector suppliers with an integrated solution to fully certify Ethernet cables and connector tests in accordance with the OPEN Alliance TC9 standard.

Rohde & Schwarz and Allion Labs became best test and measurement partners for the Automotive Ethernet market.
