As wireless devices and systems spread across every industry, spectrum analyzers serve as an essential RF test tool for characterizing signals and making frequency measurements.

Download Rohde & Schwarz's definitive guide to understanding the technology behind spectrum analyzer measurements.

This white paper provides in-depth guidance in navigating 5G VoNR from the network deployment and the connectivity options aimed at not only supporting VoNR, but also ensuring the data services that VoNR should enable. A brief summary is also provided on the signaling parameters for both the network and UE side.

Rohde & Schwarz hosts the Mobile Test Summit 2021, which will take place as a digital conference, running daily from October 25 to October 28, 2021. 

Rohde & Schwarz and Vector Informatik are collaborating on closed-loop scenario testing of automotive radar sensors for advanced driver assistance systems and autonomous driving.

Rohde & Schwarz was awarded a contract to provide the R&S KORA system for communications and radar electronic support measures for new German F126 frigates.

This application note offers a straightforward description of how to analyze EMI problems using the Rohde & Schwarz Oscilloscopes. The discussion begins by covering the basic mechanisms that can result in unwanted RF emissions and then describes how to proceed in analyzing EMI problems. Finally, a practical example is given to illustrate the analysis process.

This primer outlines the basics of RF power sensors and highlights a few key characteristics that will help you select the best one for each application. The educational note has three parts: choosing the right type of sensor, attributes of sensor performance, and we outline three ways to integrate a sensor into your measurement application.

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.

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.

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.
