Engineers often need to test the direction finding capabilities of radar warning receivers in the lab. A perfect solution is to use multiple coupled R&S®SMW200A vector signal generators that are phase-coherent and time-synchronized. This setup enables simulation of the angle of arrival (AoA) of radar signals in the lab.
Want to discover antenna measurement key parameters and over-the-air (OTA) test methods and setups? Read this white paper to learn more on the technical background for OTA testing on 5G NR devices. Focusing on RF conformance aspects and UEs, the paper examines the requirements described in the technical specifications.
Cellular-V2X (C-V2X) is a key technology which will improve road safety and accelerate autonomous driving in the coming years. Specifically, the C-V2X PC5 interface, operating in the 5.9 GHz frequency enables direct, reliable, low latency communication between vehicles (V2V), vehicles and infrastructure (V2I) and vehicles and pedestrians (V2P). In order for the automotive industry to deploy this technology in a timely manner, cooperation between suppliers in this industry becomes increasingly important.
The new R&S RTS radar test system from Rohde & Schwarz simulates driving scenarios for testing radar based advanced driver assistance systems and radar sensors used in autonomously driving cars entirely over the air.
Rohde & Schwarz is showcasing the latest highlights of its cellular device testing portfolio, which cover all stages from early 5G NR device design phases to conformance testing to device manufacturing at Mobile World Congress in Barcelona.
Rohde & Schwarz will be presenting current highlights from this portfolio at MWC21 including 5G NR physical layer parameters, which will be included in Release 17; the R&S FE44S, R&S FE50DTR and R&S Server Based Testing.
Measurements of very high noise figure components are performed for a number of reasons. For instance, in a wide range of applications, devices under test (DUT) are characterized within a complex test setup that includes high losses before or after the low noise DUT.
