Rohde & Schwarz is strengthening automotive network testing with a new ASA Motion Link compliance solution for the R&S RTP oscilloscope, addressing the growing demand for reliable high-speed data communication in modern vehicles. Asymmetric network technologies such as ASA are becoming increasingly critical as vehicles generate massive volumes of sensor data from cameras, LiDAR and radar systems. However, ensuring interoperability across a rapidly expanding multi-vendor ecosystem remains a major challenge. The new solution focuses on standards-compliant testing, streamlined device debugging and enhanced compatibility to support seamless automotive communication.
Established in 2019, the Automotive SerDes Alliance (ASA) aims to create an open standard for high-speed asymmetric Serializer/Deserializer (SerDes) technology within the automotive industry. The technology is designed to efficiently transmit data between high-resolution sensors, ECUs and ultra-wide high-definition displays while minimizing interference with sensitive vehicle electronics. With bandwidth capabilities of up to 16 Gbps per lane, ASA technology is emerging as a scalable backbone for next-generation connected and autonomous vehicles, including Level 3 autonomous driving systems and beyond.
Rohde & Schwarz has been a long-standing member of the Alliance contributing to the various technical committees to help further the open standard. The new R&S SPLUS-K105 option available on the R&S ScopeSuite+ software offers comprehensive electrical compliance testing for the latest ASA Motion Link standard. The software fully controls and automates the R&S RTP high-performance oscilloscope, allowing test engineers to be guided effortlessly through each test case via the step-by-step wizard and the web-based GUI. All relevant test cases for each speed grades (SG1 to SG5) are supported by the software. In addition, users can also control the R&S ZNB3000 and other supported VNAs, for performing accurate return loss measurements.
The combination of oscilloscope, VNA and compliance software provides capabilities for signal integrity analysis, time domain impedance analysis and accurate and repeatable measurements essential for verifying PHYs, ECUs, cables and connectors fostering reliable Automotive communication.
