The University of New Hampshire InterOperability Laboratory (UNH-IOL) is industry-recognized worldwide for Ethernet compliance testing. For this reason, Keysight Technologies and UNH-IOL have partnered to co-author a paper that will be at upcoming industry events.

Abstract of the paper:
Car manufacturers, OEMs, and chipset vendors are looking to Automotive Ethernet as a next generation communication bus. This paper introduces the testing methodologies for Automotive Ethernet. This includes current standards such as 100BASE-T1 IEEE 802.3bw, and OABR 3.2. It will also briefly discuss emerging standards such as 1000BASE-T1 IEEE 802.3bp and future variants being defined in IEEE 802.3ch and IEEE 802.3cg.

Four areas will be addressed:

  • Physical Coding Sublayer Testing
  • Physical Medium Attachment (PMA) testing including: output droop, timing jitter, clock frequency and power spectral density. 
  • Channel characterization including: common impedance differential mode (CIDM), propagation delay, insertion loss, return loss, longitudinal conversation loss (LCL), and longitudinal conversation transfer loss (LCTL).
