Keysight Unveils Advanced Physical Layer Receiver Test Solution for MultiGBASE-T1

Keysight Expands Its Automotive Ethernet Receiver Test Solution to Support MultiGBASE-T1 Data Rates

Keysight Technologies, Inc. (NYSE: KEYS) has announced a significant expansion of its Automotive Ethernet Receiver (Rx) Compliance Solution, now incorporating support for MultiGBASE-T1 data rates. This latest enhancement introduces new Receiver Test Compliance Software designed specifically for Automotive Ethernet MultiGBASE-T1, as well as an innovative custom-designed Noise Injection Fixture. These advancements are expected to drive the next generation of automotive in-vehicle network technologies, ensuring higher bandwidth, improved reliability, and superior compliance testing.

With the increasing integration of Advanced Driver-Assistance Systems (ADAS) in modern vehicles, there is a growing demand for high-resolution cameras and radar systems that require robust, high-speed data transmission. Automotive manufacturers and engineers are under constant pressure to validate the performance of receiver devices and ensure their designs comply with industry standards such as IEEE 802.3ch and Open Alliance TC15. The newly expanded Keysight solution directly addresses these challenges by providing an advanced testing framework that enhances device and system validation while also introducing automated tools to streamline the testing process.

The Growing Demand for High-Speed Automotive Networking

The automotive industry is undergoing a major transformation as manufacturers shift towards Software-Defined Vehicles (SDVs). These next-generation vehicles rely heavily on high-speed in-vehicle networking to manage sensor data, communication, and real-time processing.

The demand for faster and more efficient in-vehicle networks has been fueled by:

  • Autonomous Driving Systems (ADAS): Vehicles now come equipped with multiple cameras, LiDAR, and radar sensors that generate vast amounts of data. Transmitting this data in real-time requires high-bandwidth Ethernet solutions.
  • Connected Vehicle Technologies: With Vehicle-to-Everything (V2X) communication, modern cars must interact seamlessly with traffic infrastructure, cloud-based services, and other vehicles.
  • Zonal Architecture for SDVs: As automakers shift towards zonal networking, Ethernet has become the backbone of modern vehicle architecture, necessitating solutions that can handle multi-gigabit data rates efficiently.

Recognizing these trends, IEEE 802.3ch and Open Alliance TC15 have established standards to ensure the seamless implementation of MultiGBASE-T1 technology, which supports automotive networks with data rates beyond 1Gbps.
