R&S ZNB vector network analyzer from Rohde & Schwarz.

Raydiall and Yazaki validate SPE connectors for Ethernet 1000BASE-T1 with Rohde & Schwarz’s VNA

  • Raydiall, a manufacturer of FAKRA and HSD connectors for the automotive industry, and its partner Yazaki, a supplier of automotive wiring harnesses, connectors and other interconnect interfaces, have developed a Single Pair Ethernet (SPE) connector for 1000BASE-T1 in accordance with the OPEN Alliance TC9 specification.
  • Raydiall validated the development and tested the compliance of its connectors with the Rohde & Schwarz R&S ZNB8 4-port vector network analyzer.

Raydiall Automotive, in collaboration with its Japanese partner Yazaki, has developed various connection and cabling components for automotive Ethernet communication links: assembled cables (cable harnesses and connectors), PCB headers, in-line connectors and stand-alone communication channel (SCC). All of these components have been tested against the OPEN Alliance (OA) Technical Committee (TC) 9 test specification for 1000BASE-T1 Shielded Twisted Pair (STP). This assures their OEM customers and Tier 1 suppliers of their high quality standards.

The OPEN Alliance TC9 specification requires various measurements such as return loss (RL), insertion loss (IL), mode conversion (LCL & LCTL) as well as screening and coupling attenuation parameters which represent both emission and immunity of its products. With the R&S ZNB8 vector network analyzer, which uses the R&S ZNB-K2 time analysis software option, characteristic impedance measurements (CIDM) are performed in the time domain.

The Rohde & Schwarz vector network analyzer is suitable for testing according to the OPEN Alliance TC9 test specification. It can perform all the necessary measurements in both the frequency and time domain. In addition, for in-line and header connectors, the R&S ZNB has been implemented with the R&S ZN-K220 software option using Ataitec’s ISD (In Situ De-embedding) technique. This functionality allows the performance of these components to be verified in accordance with the OPEN Alliance TC9 test specification.
