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.

罗德与施瓦茨推出不同的模拟信号发生器和数字信号发生器：涵盖射频矢量信号发生器、基带信号发生器和微波信号发生器。

对于使用用户自定义协议的应用，r&s®ex-iq-box 可用于将 i/q 信号串行或并行传输到 dut，涵盖可变时钟模式、不同数据率以及不同的逻辑信号电平。 通过可直接插入 r&s®ex-iq-box 的适配器插板（即接线板），可以直接连接到被测设备。在使用标准协议的应用中，r&s®ex-iq-box 不仅提供 i/q 数据，而且提供各项标准的控制信息。 在配备相应选件的情况下，r&s®ex-iq-box 支持标准化接口协议 cpri™（通用公共射频接口），它还定义了一个用于在基站的基带以及射频模块之间传输 i/q 和控制数据的接口。参数可通过 r&s®digiconf 数字接口配置软件轻松设置。在配备 r&s®ex-iq-box 的情况下，矢量信号发生器能够提供用于测试数字收发信机或其他组件的实际数字基带信号。

this document provides the technical specifications of the r&s®ex-iq-box digital signal interface module (model .k04).

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.

iqwizard 工具可用于加载不同格式的 iq 信号文件，并使用 fsx 频谱分析仪或 esx 接收机测量 iq 信号。 内存中获取的 iq 数据可存储为不同格式或者传输至带有 winiqsim™ 或 winiqsim2™ 的 r&s® 矢量信号发生器。
