Automotive GNSS Emulation and Testing
As vehicles increasingly rely on precise positioning for ADAS, V2X, eCall, autonomous driving, and intelligent speed assistance (ISA), validating GNSS performance under real-world conditions becomes critical. Keysight provides an automotive GNSS emulation and testing solution that enables GNSS receiver testing, vehicle positioning validation, and sensor fusion development in a repeatable laboratory environment. Powered by the PNT Xe platform, Keysight combines multi-constellation GNSS simulation, HIL integration, and automated test execution to help OEMs, Tier 1 suppliers, chipset vendors, and test laboratories accelerate development, reduce road testing, and improve positioning performance.
Fast Communication With Low Latency
The automotive industry is adding greater complexity with more and more ADAS sensors and systems, while at the same time trying to simplify the networks that carry the data within vehicles. Higher bandwidth and lower latency networking will play a critical role in addressing time-sensitive and complex automotive technologies to come like Automotive Ethernet and standardized Automotive SerDes. However, there will undoubtedly be a place for the lower speed serial protocols like CAN and LIN for many years to come. Keysight addresses all these technologies and more.

Frequently Asked Questions
Choosing the right automotive communications testing solution depends on the technology you need to validate and the test objective. For in-vehicle communications, Keysight solutions cover Automotive Ethernet from 10M to optical, as well as Automotive SerDes technologies such as MIPI A-PHY, ASA, OGA, and more. These solutions focus on transmitter, receiver, and channel testing to help verify signal integrity, interoperability, and compliance.
For connected vehicle applications, vehicle-to-everything (V2X) emulation and testing solutions support V2X development, deployment, field testing, certification, simulation, and analysis from the lab to the field. eCall / ERA-GLONASS testing focuses on emergency safety conformance by simulating the in-vehicle system, GNSS, cellular network, and public service answering point (PSAP) needed to verify emergency call behavior and MSD transmission.
Automotive communications systems require different tests depending on whether the system is an in-vehicle network, emergency calling system, or V2X system. In-vehicle communications testing includes physical-layer solutions for the transmitter, receiver, and channel, helping engineers verify functionality, performance, signal integrity, interoperability, and compliance across modern automotive networking systems.
V2X testing includes RF, protocol, and functional testing for C-V2X, including Uu and PC5 interfaces, while eCall / ERA-GLONASS conformance testing verifies whether an in-vehicle system or modem can trigger an emergency call, send the correct raw MSD data, and establish a voice connection with the PSAP.
Key specifications include the supported automotive communication technology, data rate range, bandwidth, latency requirements, physical-layer coverage, protocol support, and the ability to test transmitters, receivers, and channels. These considerations are especially important for Automotive Ethernet and Automotive SerDes, which support faster communication between edge devices such as cameras, sensors, and high-performance computing systems.
For V2X and emergency calling applications, consider whether the solution supports RF, protocol, functional, field, lab, certification, simulation, and conformance testing requirements. Test setup flexibility is also important, including software and accessories such as fixtures, cables, adapters, and application-specific tools for Automotive Ethernet and SerDes compliance testing.
Automotive communications testing covers technologies such as Automotive Ethernet, Automotive SerDes, CAN, LIN, C-V2X, eCall, and ERA-GLONASS. Automotive Ethernet test coverage can span 10M to optical links, while Automotive SerDes technologies include MIPI A-PHY, ASA, OGA, and other high-speed in-vehicle connectivity standards. Lower-speed serial protocols such as CAN and LIN also continue to support many vehicle control and body electronics applications.
Testing needs vary by technology. Automotive Ethernet and SerDes testing focuses on signal integrity, interoperability, compliance, and channel-related validation for harnesses, cables, connectors, transmitters, and receivers. C-V2X testing verifies RF, protocol, and functional performance of Uu and PC5 interfaces, while eCall / ERA-GLONASS testing verifies emergency call conformance using emulated network and PSAP elements.
Automotive communication systems are tested by recreating realistic operating conditions in controlled lab, field, simulation, and analysis environments. For in-vehicle networks, this includes evaluating higher-bandwidth and lower-latency communication needed for ADAS sensors, complex vehicle networks, Automotive Ethernet, and standardized Automotive SerDes.
For V2X, Keysight solutions support lab emulation, field testing, development, deployment, certification, simulation, and analysis. These capabilities help engineers evaluate V2X modules and systems across RF, protocol, and application layers before deployment in connected and autonomous vehicle environments.
Automotive communications testing can be integrated from early development through validation, conformance, certification, and deployment. In-vehicle communications test solutions support design and test workflows for verifying the functionality, performance, and interoperability of automotive networking systems, including Automotive Ethernet and Automotive SerDes.
For V2X, testing can span lab emulation, field testing, certification, simulation, and analysis. For eCall / ERA-GLONASS, conformance testing can be performed independently of a real-world mobile network by emulating the cellular network and related emergency-call system elements, helping teams verify emergency safety behavior before deployment.
