特点与优势
宽频率范围高达6 GHz
带R＆S®CMW-Z11的R＆S®CMW-Z10适用于高达6 GHz的应用，因此涵盖了GSM，UMTS，LTE，CDMA2000®，WLAN，Bluetooth®和GPS等所有常见无线标准。它提供了高屏蔽效能，使外部干扰的影响降至zui低。
超低的反射
RF屏蔽盒的盖子衬有吸收材料以减少反射。作为DUT位置的函数，强反射会引起衰减的显着变化。
模块化选项概念和灵活的模块分配
带R＆S®CMW-Z11的R＆S®CMW-Z10具有四个用于不同可选模块的模块插槽。可用的选件目前包括25针D-Sub馈通（R＆S®CMW-Z12），USB 2.0馈通（R＆S®CMW-Z13），双N连接器（R＆S®CMW-Z14）和15针D- Sub馈通（R＆S®CMW-Z15）用于双向音频测试。也可以插入客户特定的模块。
足够的空间可以实现定位，即使对于诸如平板电脑等大型DUT也是如此
即使是大型DUT，例如平板电脑，也可以适应。 RF屏蔽盒为定位DUT提供了充足的空间，可以zui大限度地减少DUT和测试仪之间的耦合衰减。
专为苛刻的，持续的工作和人体工程学操作而设计
射频屏蔽盒设计可承受服务和制造环境中遇到的恶劣条件。关闭机构经过优化，符合人体工程学使用，确保防疲劳操作，同时提供高质量的结果。
天线分集和MIMO测试
R＆S®CMW-Z16第二个天线选件是圆极化的第二个天线元件，可以测试发射分集天线和多输入多输出（MIMO）系统。
R＆S®CMW-Z16安装在射频屏蔽盒的背面，可实现MIMO DUT（如LTE MIMO 2x2）的辐射耦合。标准天线向第二个天线元件（R＆S®CMW-Z16）提供90°方向的耦合场。这提供了近场环境中MIMO设备的耦合。
双向音频测试
R＆S®CMW-Z15音频测量选件提供R＆S®CMW-Z10中双向音频测量所需的附件。音频测量所需的麦克风和扬声器可以地定位在RF屏蔽盒内。音频信号通过屏蔽D-Sub馈通传输，以zui大限度地减少外部干扰对屏蔽盒特性的影响。音频信号通过RF接口传输到无线电通信测试仪的音频编码/解码器。音频路径可以通过比较原始信号和恢复的信号来测量。
