A Vector Network Analyzer (VNA) natively measures complex S-parameters of a device under test (DUT) in the frequency domain mode by sweeping across various frequency points. While there is an exhaustive list of measurements that can be accomplished in the standard frequency domain mode – using the advanced inverse Chirp z-transformation, the measurements can also be simultaneously analyzed in the time domain mode. This gives the added advantage where the two fundamental modes of analysis can be performed by one single instrument.

On Saturday, May 30th, people across the world watched in awe as SpaceX launched a rocket, designed independently of any government, putting two astronauts into orbit on their way to the International Space Station — the first time in history for any commercial company. Ten years ago, this would have been an unthinkable endeavor for any commercial or private organization.

Your challenge: Testing coexistence and user experience to ensure high quality of service in real-world use, and ensuring security and product compliance for risk free market introduction. Rohde & Schwarz is a one-stop shop catering to all wireless RF coexistence test and measurement requirements.

5G is now - what´s next?

5G deployments have only recently started, and releases beyond R15 will continue to tap into the tremendous potential of 5G. However, 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.

This white paper provides an overview of the basic building blocks of a phased array system and discusses how the nature of their design leads to a challenging test environment.

Real measurement configuration examples are shown to highlight the flexibility required for T/R module testing.

In many applications it is necessary to make multiport measurements. The RNVNA links up to 16 1-Port analyzers together into a multiport network analysis system. Each of the 16 analyzers will make individual vector reflection measurements and scalar transmission measurements from port to port. In other words, S11, S22, S33 and so on will be complex measurements and S21, S31, S41 and so on will be scalar only measurements.

This application note introduces the Jitter analysis capabilities of the R&S® RTO Digital Oscilloscope and the Jitter option R&S®RTO-K12 for digital signals. It provides background information on jitter sources and standard jitter measurement tools. Furthermore it demonstrates Period jitter, Cycle jitter and Time Interval Error jitter measurements based on an application example. The benefits of different representations of the measurement results with histogram, track and spectrum display are discussed.

Wi-Fi and 5G are enablers of autonomous vehicles. The challenge lies in how these technologies work together and co-exist ¬without impacting vehicle operation and passenger safety. This paper discusses Wi-Fi and 5G, how they co-exist with selectivity filter solutions to enable vehicular communications and passenger safety.

The automated test and measurement (ATE) landscape is rapidly changing, progressing beyond the capabilities of traditional bench-top and most legacy ATE systems. Varying and diverse performance requirements, testing speeds and frequencies used by modern cellular architectures (5G), Internet-of-Things (IoT) devices, and the latest feature dense systems-on-chip/systems-inpackage (SoC/SiP) necessitate a different approach.

HF stands for “high frequency” and is usually used to refer to signals with frequencies in the range of 3 MHz to 30 MHz, although in many cases the practical definition of HF has be extended down to frequencies as low as 1.5 MHz.
