Achieve optimal performance and security for in-vehicle networking
Accelerate Your Automotive In-Vehicle Networking Innovations
Automotive in-vehicle networks are evolving rapidly to provide the high-speed data transfer demanded by the connected car. Technologies like automotive Ethernet, automotive SerDes, and conventional buses like CAN, CAN-FD, LIN, DDR, and others will come together to meet evolving performance requirements.
Enabling communication, safety, convenience, and electrification applications expected in modern and future software-defined vehicles (SDV) requires managing increasing data volumes and speeds. Keysight automotive in-vehicle networking solution offers the high-performance design and test platforms you need to deliver your automotive innovations faster and better.
Testing Layers 1–7 of Automotive Ethernet
Automotive Ethernet
Advanced driver assistance systems (ADAS) and autonomous vehicles use lots of sensors, controls, and interfaces with higher bandwidth requirements. Automotive Ethernet provides a single universal medium for communication that allows different components to coexist on the same switched network.
Keysight offers full-stack conformance test solutions for Layers 1–7 for automotive Ethernet to ensure network integrity for compliance, decode, TSN, TCP/IP stack testing, as well as safe and secure performance of the connected car.
Automotive SerDes
Cameras sensors for ADAS need high data rate and transmission speeds to function as designed. Increasingly, developers are turning to serializer/deserializer (SerDes) connections to link these cameras to the vehicle’s image-processing electronic control units (ECUs).
These SerDes connections convert parallel data to serial data (and vice-versa), enabling faster communication between devices using lower-cost cables and connectors.
Keysight and UNH Collaborate to Advance Automotive Ethernet
You must have unfailing trust in both your test plans and your test equipment to ensure your automotive Ethernet products meet specifications with accuracy and reliability. The University of New Hampshire InterOperability Laboratory (UNH-IOL) is industry-recognized worldwide for automotive Ethernet compliance testing.
For this reason, Keysight Technologies and UNH-IOL have partnered to co-author these virtual online learning events for you.
Keysight's Automotive Ethernet Physical Layer Solutions at Work
Test and debug serial buses with oscilloscopes
The oscilloscope is the primary measurement tool used today to test and debug the physical layer of automotive serial buses, including CAN, CAN-FD, LIN, SENT, and MOST.
Automotive in-vehicle networks must function in harsh electrical environments, with lots of noise and unexpected transients. An oscilloscope can capture and show you details of infrequent automotive transients and noise that are producing bus errors.
Keysight offers a broad range of automotive serial bus applications in both the InfiniiVision and Infiniium oscilloscope families, including protocol decode/trigger, eye-diagram mask testing, and physical layer compliance test packages.
Identify and prevent cyberattacks before they occur
The modern Connected Car is a supercomputer on wheels, but its connectivity makes it vulnerable to potential cyberattacks. Keysight is helping industry leaders secure the Connected Car with penetration (Pen) tests for all relevant interfaces. Besides protection with up-to-date threat databases, our automotive cybersecurity solutions can be integrated with client custom databases.
