Automotive radar is vital to the advanced driver assistance systems (ADAS) that will help achieve Net Zero (zero accidents, zero fatalities) targets in the automobile industry. In a driving environment, radar sensors must detect real objects even when there is interference. The R&S®AREG800A automotive radar echo generator is essential to any solution that tests radar sensor immunity to interference.

AVL adds Rohde & Schwarz GNSS stimulation to vehicle test environmentGNSS signals (for example GPS signals) are of major importance for positioning and tracking, orientation and safety-related information, such as congestion, in road traffic. A collaboration between AVL and Rohde & Schwarz, two of the world’s leading providers of measuring and automotive testing systems, now permits the reproduction of realistic GNSS reception conditions for testbed vehicle testing. As a result, users can reliably test all aspects of GNSS-based vehicle positioning – a core functionality of autonomous vehicles.

Evolution of Carrier Aggregation (3GPP Release 10 to 13) - Poster
Find out more about active electronically scanned array and antenna testing.
This application note addresses the diverse possibilities of interoperability between Rohde & Schwarz power sensors and Rohde & Schwarz signal generators. All current and many legacy Rohde & Schwarz signal generators offer the capability of directly connecting power sensors. This enables power measurements without the need of a base unit or separate PC to display the readings. Furthermore, sensors can be used for special tasks like filling a user correction table or continuously controlling levels at crucial points in the measurement configuration.
