5G networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. Two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: Virtualization & Massive MIMO. This white paper provides an overview of test solutions addressing current and future requirements for antenna verification including both conducted and over-the-air (OTA) test methods, which result from applying Massive MIMO antenna technology.This white papers complements the white paper (1MA276) from Rohde & Schwarz, which introduces fundamental theory behind beamforming antennas and provides calculation methods for radiation patterns, a number of simulation results as well as some real world measurement results for small linear arrays.

Welcome to this introductory video show about the R&S® ZVA family of network analyzers. Network analysis is sometimes considered to be cumbersome and difficult to understand, a very offputting reputation for newcomers to network analyzers. To help you look at network analyzers in a different light, we have created this video series. We have intentionally refrained from explaining any theory in depth. Rather, we want to show you how to operate our analyzers for simple and useful applications. As well as just watching this video show, you can also use it as a guide and try yourself. All the operational steps shown only require a standard RF power amplifier which should be available in almost every lab. So, before we get properly started, we hope you enjoy this video show and much success in becoming familiar with network analysis in general, and our R&S products in particular.

This application note shows how to remote control the switching of RF and digital I/O signals by R&S®OSP Open Switch and Control Platform directly from a Vector Network Analyzer (VNA) or from a Spectrum Analyzer (SA). The R&S®ZVA, R&S®ZVB, R&S®ZNB, R&S®FSW and R&S®FSV families are covered. The application note first describes the requirements and setup procedure. It is shown how to install the software and how to set up the system in order to get highest flexibility and best usability. It is then shown how to calibrate the entire configuration and finally some practical examples are provided. Switching is explained using VNAs as an example, the appendix 5.4 provides hints regarding the differences when using SAs in a similar way.

This Application Note describes testing S-parameters under pulsed conditions with the R&S®ZVA vector network analyzer and either the ZVAX24 Extension unit with pulse modular option or the R&S®SMF signal generator with pulse modulator as a signal source.In addition a constant power level calibration for applications requiring high drive power for test and measurement of device under test (DUT) is also included. A LDMOS S-band radar power transistor is used as example DUT. The pulse profile mode of the R&S®ZVA is used to analyze the time-dependent behavior of the DUT.

Rohde & Schwarz instruments can be shared when users wish to use the same instrument. This can be done quite easily with the LAN interface, which comes as a standard option. Through this interface, Rohde & Schwarz instruments can be connected directly to a network, and users with access to the network can manually operate the instrument from a remote computer. This Application Note lists all instruments that support these features and describes the steps necessary to set up and configure the network connection to operate these instruments remotely.
