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.

Rohde & Schwarz has joined the FiRa Consortium as an associate member. The FiRa Consortium focuses on three core UWB services: hands-free access control, location based services and device-to-device services that rely on the latest UWB based secure ranging technology specified by the IEEE 802.15.4z.

Rohde & Schwarz is demonstrating its latest test solutions for 5G and other wireless standards, connected cars and mobile network testing at booth N1.B70 of the SNIEC at MWC Shanghai from February 23 to 25.

The steady extension of the Rohde & Schwarz portfolio of specialty power supplies continues with the first two models in the R&S NGU series of high precision SMUs, providing both maximum sensitivity and accuracy to reliably measure currents from nA to A in a single sweep.

Today’s satellite communication systems combine features from legacy cellular networks and emerging wireless technologies. New constellations are under development that attempt to provide ubiquitous mobility and internet networks via satellites, ground stations and user terminals (Figure 1). Each link in the supply chain presents unique challenges for R&D, production and deployment for both the components and system development.

For automated test applications, measurement time is often as important as the quality of the measurement. In practice, phase noise measurements are generally not considered fast, but test engineers still desire to save as much test time as possible. With this paper you get a modern, digital signal processing based, phase-noise test set that performs many tasks in parallel in an effort to improve measurement speed.

Review of different ways to overcome the challenges of RF measurements in the E band for ultra wide signals. It will look at the demodulation, analysis of a wideband automotive radar signal and discuss the results and main performance parameters.

Most ADAS functions rely on radar sensors, and these safety-critical components must function correctly even under the most demanding of RF environments. This white paper describes a test procedure to replicate real life scenarios where the ADAS radar functions are activated during EMS testing and it contains some very interesting results.

5G is now and what’s next? As a new generation of cellular technology typically appears every 8-10 years, 6G can be expected around 2030. Download this white paper to explore the evolution from 5G to 6G from a service, air interface and network perspective.
