Rohde & Schwarz has released an Automotive SerDes Alliance (ASA) Motion Link (ASA-ML) compliance solution aimed at testing in-vehicle high-speed asymmetric networks used to transport growing volumes of sensor and display data.
The company says the new option, R&S SPLUS-K105 within its ScopeSuite+ software, provides electrical compliance testing for the latest ASA Motion Link standard when used with the R&S RTP oscilloscope. The release comes as automakers and suppliers seek interoperability across a multi-vendor ecosystem while integrating higher-bandwidth components such as high-resolution cameras, LiDAR and radar sensors.
ASA was formed in 2019 to develop an open standard for high-speed asymmetric Serializer/Deserializer (SerDes) technology. Rohde & Schwarz said it has participated in ASA technical committees, and that ASA links can scale up to 16 Gbps per lane to support data-intensive functions, including advanced driver assistance systems.
According to the company, the compliance software automates RTP oscilloscope testing through a step-by-step wizard and web-based GUI, supporting test cases across ASA speed grades SG1 to SG5. It can also control the R&S ZNB3000 and other supported vector network analyzers for return loss measurements.
Rohde & Schwarz said the combination of oscilloscope, VNA and compliance software is intended to support signal integrity and time-domain impedance analysis for verification of PHYs, ECUs, cables and connectors.
