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/

The R&S®NRP2 power meter offers a remote emulation feature that makes it possible to control the instrument by commands other than the built-in native SCPI commands. This feature allows the user to replace power meters, e.g. from other manufacturers, with the R&S®NRP2 power meter without having to change the remote control code. This application note describes how to use the remote emulation feature in general. Furthermore, it describes in detail the remote emulation for each supported instrument, limitations of the individual emulations and the remaining differences between the emulated and the original commands.

This document presents a simple procedure for network analysis that is more cost-effective than the use of scalar network analyzers. It allows the accurate measurement of the transmission characteristics of filters, amplifiers and frequency converters over a large frequency and dynamic range. In order to reach very high measurement speeds, Rohde & Schwarz signal generators are operated in 'List Mode', and Rohde & Schwarz power meters are operated in 'Buffered Mode.' The required programming for the signal generator and the power meter is illustrated by excerpts from a Visual Basic program which is available, free of charge, upon request.
