Raydiall & Yazaki verify Single Pair Ethernet (SPE) connectors for 1000BASE-T1 with the support of Rohde & Schwarz

06/04/2021

Raydiall Automotive have been developing, together with their Japanese partner Yazaki, various automotive ethernet components for the link segment (communication channel) section. Such components are cable assemblies (cable harness and connectors), PCB headers, in-line connectors and the standalone communication channel (SCC). All of them had to undergo extensive testing against the OPEN Alliance (OA) Technical Committee (TC) 9 test specification for 1000BASE-T1 Shielded Twisted Pair (STP) to provide their OEM and Tier1 customers high quality assurance.

In the OA TC9 are several measurements that need to be performed 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. The characteristic impedance measurements (CIDM) are done in the time domain thanks to the R&S ZNB-K2 time domain analysis software option of the R&S ZNB8.

The vector network analyzer from Rohde & Schwarz is the perfect T&M tool to perform tests according to the OA TC9 test specification since it can provide high measurement accuracy as well as support all the necessary frequency and time domain measurements needed. In addition, for in-line and header connectors, the R&S ZNB VNA has integrated the Ataitec ISD software option R&S ZN-K220 which is a unique feature to verify performance of such components according to the OA TC9 test specification.
