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.

IQWizard는 FSx Spectrum Analyzer 또는 ESx Receiver를 사용하여 다양한 형식의 IQ 신호 포맷을 로드하고 IQ 신호를 측정하는 툴입니다. 메모리에서 획득한 IQ 데이터는 다양한 형식으로 저장하거나 WinIQSIM™ 또는 WinIQSIM2™를 사용하여 R&S® 벡터 신호 발생기로 전송할 수 있습니다.

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).

칩셋 또는 모듈의 설계 과정에서 FPGA 기반 하드웨어 에뮬레이터를 활용하여 조기에 테스트를 수행할 수 있습니다. 이러한 하드웨어 에뮬레이터는 일반적으로 인위적으로 감소된 속도로 실행되지만 이 기능을 제외한 나머지는 완료된 설계와 동일합니다.이 애플리케이션 노트에서는 감소된 샘플링 속도에서 적절한 실시간 테스트 신호를 만드는 로데슈바르즈 벡터 신호 발생기를 사용하여 FPGA 기반 하드웨어 에뮬레이터를 테스트하는 방법에 대해 설명합니다. 또한 "Slow I/Q"에 대해 AWGN 신호 발생 및 페이딩 시뮬레이션을 올바르게 대응하는 방법에 대해서도 설명합니다.

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.

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.
