The R&S EX-IQ-Box serves as a digital baseband interface between a device under test (DUT) and Rohde & Schwarz generators, analyzers and radio communication testers. The DigIConf software supplied with the device controls up to four R&S EX-IQ-Boxes in a test setup and can thus output IQ data for feeding into a DUT while simultaneously receiving IQ output from a DUT.To work together smoothly, the DUT, the R&S EX-IQ-Box and the R&S test instruments have to be configured properly. The purpose of Application Note 1MA168 is to introduce the right 'initial steps' required to get started successfully.

IQWizard is a tool for loading IQ signal files in various formats and measuring IQ signals with a FSx spectrum analyzer or ESx Receiver. The obtained IQ data in memory can be stored in various formats or be transmitted to an R&S® vector signal generator with WinIQSIM™ or WinIQSIM2™.

This application note explains how to bring a CADENCE system which is attached to an R&S EX-IQ-BOX into service for the first time. The first part of the document shows how to setup an LTE Demo without using a UE design. This setup uses the R&S CMW500 as the downlink transmitter. The emulator receives the downlink via an R&S EX-IQBOX and passes it to an R&S spectrum analyzer (R&S FSx) via a second R&S EXIQ-BOX. The second part describes the real wiring using up- and downlink. This will only work if a UE design is available on the emulator.

This document provides the technical specifications of the R&S®EX-IQ-Box digital signal interface module (model .K04).

Describes all instrument functions and remote control commands, as well as measurement and programming examples.The online version is meant for immediate display (no download required).

More and more mobile radio networks implement remote radio equipment (RE) that is connected to the base station main unit via a digital interface using standardized transmission protocols such as CPRI. For testing RE devices Rohde & Schwarz offers a complete test solution based on the R&S®EX-IQ-BOX [Model K04]. This key component is a configurable digital interface module that is used to connect Rohde & Schwarz test equipment to a RE under test using CPRI data transmission.This application note explains in detail the instrument setup and configuration needed to successfully test your remote radio head.

Multiple input multiple output (MIMO) technology is an integral part of 3GPP E-UTRA long term evolution (LTE). As part of MIMO, beamforming is also used in LTE. This application note provides a brief summary of the transmission modes (TM) in LTE and describes the beamforming measurements for base stations (BS) and user equipment (UE). The T&M options using various Rohde & Schwarz instruments are also presented.

The R&S®WinIQSIM2™ simulation software has been especially developed for easily generating digitally modulated signals. The graphical user interface allows intuitive operation, supported by context-sensitive help. By offering a convenient way to create any standard-conforming waveform with all the included standards and to generate multicarrier signals as well as multisegment waveforms, R&S®WinIQSIM2™ is suitable for a wide range of applications.
