Automotive Ethernet Channel Testing

Introduction

Next-generation ADAS systems require camera and radar systems with increasingly high resolution. That means new requirements for speed and bandwidth. Automotive Ethernet enables faster data communication to meet the demands of today’s vehicles and the connected vehicles of the future.

Unlike other serial technologies in the car, CAN, LIN or MOST, Automotive Ethernet demands rigorous compliance verification. The requirements include complex measurements that, until recently, have been uncommon in the auto industry: vector network analysis measuring and monitoring cross talk, insertion loss, mode conversion between all, and any cables bundled together in an Automotive Ethernet network. The channel or link in any system can create a point of failure and must be thoroughly tested.

To help you save time and effort, Keysight offers solutions that automate the testing and validation of Automotive Ethernet designs. These proven applications help ensure proper test configuration and valid, repeatable measurement results. The net result: you’ll have greater confidence that your device complies with the IEEE standard, a faster development cycle, repeatability of testing, and less human error.

Harness and Connector Validation

The AE6000L Automotive Ethernet channel compliance solution provides an easy and accurate way to verify and debug Automotive Ethernet harness assemblies, cables, and connectors. The channel, in this case, represents the complete wired connection between two transmit/receive modules with an Automotive Ethernet interface using a two-wire twisted pair cable. The AE6000L Automotive Ethernet channel compliance solution, verifies that information is carried, without loss or cross-talk, to its intended destination. Performing these tests is required and will give you confidence in your design/s. The Keysight AE6000L link segment solution will save you hours of valuable time with configuration, instrument setup, calculations, and report generation.

Link segment = Cabling + Inline connectors + Mating connectors

The Connector type is not standardized and will be specific to each connector vendor. The Keysight AE6000L channel compliance solution greatly simplifies automotive ethernet harness and connector compliance testing for 100M, 1000M, and 2.5/5/10GBASE-T1.

Test Specifications

The AE6910L Automotive Ethernet channel compliance software covers the specifications for open alliance and IEEE as follows.
