Production Testing of Single Pair Ethernet Wiring in Cable Harness
by Arvind C Patel, Harshang Pandya, Nway Yu Khine, Krishna Rajan
The article reviews the relevant Standards for Single Pair Ethernet (SPE) and the parameters that need to be measured for compliance to the Standards. Reference Methods for Testing and Measurement addressed in the Standards are suitable for R&D and Laboratory environment. Alternate methods for Production Testing will be discussed. Measurement Data for various test configurations will be compared to give insight into factors that affect RF measurements and the appropriate methods that can be used for optimized production testing. Tester scalability techniques that can be used to expand RF Test capability for high pair count cable assemblies will be presented.
