The R&S® ZVA-Z110 converters offered for the R&S® ZVA family enable network analysis in the W band (75 GHz to 110 GHz). In this Application Note, measurements with three or four converters will be discussed. Test configurations for such measurements have so far been implemented only with coaxial connector systems for a frequency range up to approx. 40 GHz. The term 'multiport measurements' was created for this type of measurements.

Rapid and accurate verification of beamforming weights is required for example, for codebook generation or beamforming algorithm development or verification. This document describes the unique application of Rohde & Schwarz VNA (Vector Network Analyzers) to fully characterize the passive part of multi-element antennas intended for beamforming.A range of R&S VNA models are optionally equipped with multiple independent sources, whose relative amplitude and phase may be arbitrarily controlled ("defined coherence mode"), in addition to frequency and true time delay. These sources may be connected to individual elements of a multi-element antenna to derive and verify transmit (Tx) mode beamsteering and beamforming operation.The R&S®ZVA in "Defined Coherence Mode" can electronically be switched to / from the conventional S-parameter mode. Therefore, Sparameter and beamforming measurements may be performed efficiently within a single connection cycle of the antenna.Multiple VNA may be daisy-chained, to extend the concept shown to support an arbitrary number of ports.The R&S®Quickstep sequencing software may be downloaded from:https://www.rohde-schwarz.com/software/quickstep/

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.

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.

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.

Designing and implementing an active phased array antenna requires precise characterization of individual components and the integrated performance of the array. To ensure an accurate test of the intended adaptive nature of the active phased array antenna, the embedded algorithms need to be tested as well.This application note aims to explain test procedures and give recommendations towards characterization of the relevant parameters for active phased array antennas and their passive subsystem, as often used in applications for Mobile Communication and RADAR. This application note describes transmit signal quality testing, multi-element amplitude and phase measurement techniques both in receive and transmit cases and introduces a new automated test methodology antenna radiation pattern measurement over frequency. This paper also describes the test system used for transmit and receive module (TRM) characterization in active array antennas.

This application note reviews a new calibration subsystem which consists of Inline Calibration Units (ICUs). These ICUs are designed for in situ use, so they are left in place both during the calibration procedure and during the measurement of the Device Under Test (DUT).This adds versatility, convenience and accuracy to the VNA based measurement system, as it means the calibration can be refreshed at any time without manually disconnecting the DUT from the test system.
