Automotive Ethernet Link Segment Compliance Solution  

Harness and Connector testing made easy for your 100BASE-T1 components

The Keysight Technologies, Inc. E6963A automotive Ethernet link segment compliance software provides you with an easy and accurate way to verify and debug BroadR-Reach and/or 100BASE-T1 harness and connector designs and components. Autonomous vehicles promise to change the nature of commercial and passenger transportation over the roadways. The future requirements for data speed and bandwidth demand the next-generation performance of automotive Ethernet. Automotive Ethernet enables faster data communication to meet the demands of today’s vehicles and the connected vehicles of the future. Unlike CAN, LIN or MOST buses used before, the IEEE standard for automotive Ethernet demands rigorous compliance verification with test cases that cover Tx, Rx and harness/connector assemblies. Keysight’s full suite of automotive Ethernet solutions automate testing and validation across Tx, Rx and link segment for 100 Mb/s and 1000 Mb/s automotive Ethernet. The E6963A automotive Ethernet link segment test software lets you automatically execute Ethernet physical-layer (PHY) electrical tests for harness and connector compliance using IEEE 802.3bw specifications. The E6963A displays the results in a flexible report format. In addition to the measurement data, the report provides a margin analysis that shows how closely your device passed or failed each test. The E6963A automotive Ethernet link segment test software provides five test modes for testing and validating the complete communication channel. The Whole Communications Channel represents the complete wired connection between two transmit/ receive modules with an Ethernet interface using a two-wire twisted pair cable. To meet signal quality requirements, your product must successfully pass conformance testing. Performing these tests is not only required but will give you confidence in your design/s. The Keysight E6963A link segment software will save you hours of valuable time with configuration, instrument setup, calculations and report generation. Using the Keysight E6963A link segment compliance application (100BASE-T1 compliant) software greatly simplifies automotive ethernet harness and connector compliance testing. The E6963A link segment compliance application is available in the following license variations.  

– E6963A-1FP Fixed to E5071C vector network analyzer

– E6963A-1TP Server-based transportable license

Features  

Using the Keysight E6963A link segment application software greatly simplifies compliance testing of your harness and connectors using automotive Ethernet. The Keysight link segment compliance software offers several features to simplify the validation of automotive Ethernet harness and connector designs:  

The E6963A software:  

– Guides you how to make connections to the device under test

– Automatically checks for proper configuration

– Sets up the ENA for each test

– Produces an automated test result calculation including correction for impedance profile slope and summing of all four S-parameters

– Creates a simple Pass/Fail judgement for each test

– Complies with link segment testing per BroadR-Reach V3.2 (OPEN alliance PMA test suite version 2) as well as IEEE 802.3bw (100BASE-T1) specifications

E6963A Link Segment Compliance Software  

The E6963A link segment test software saves you time by setting the stage for automatic execution of 100BASE-T1 harness and connector tests. Some of the difficulties of performing tests for 100BASE-T1 link segments are properly connecting to the vector network analyzer, loading the proper setup files, and then analyzing the measured results by comparing them to limits published in the specification. The 100BASE-T1 link segment application does much of this work for you. There are two different governing bodies of these automotive ethernet standards. The specifications from IEEE 802.3bw issued on October 2015 defines electrical specifications for 100BASE-T1. The OPEN Alliance 1 test suite for BroadR-Reach (OABR) physical layer transceiver specification for automotive applications V3.2 dated June 24th, 2014 in addition to other things, establishes the communication channel in version 2.0 that sets the test procedure of wire harnesses and connectors. Keysight E6963A BroadR-Reach Link segment test software incorporates both the specification and the test suite so that you do not need to be an expert on either. The automotive Ethernet standard is designed to operate over a one-pair balanced cabling system. The one pair UTP (Unshielded Twisted Pair) cable supports an effective data rate of 100 Mb/s in each direction simultaneously. The link segment for a BroadR-Reach PHY system is defined as one pair 15m UTP balanced copper cabling, two inline connectors and two end connectors. The transmission parameters of the link segment include insertion loss, return loss and characteristic impedance of the cable, the connector and the cable plus the connector (the whole communication channel). 2 The Keysight E6963A link segment software has a total of 5 tests to cover all the required tests and parameters.
