TS7121屏蔽射频测试盒
使用屏蔽的射频盒是可靠地测试无线电接口的先决条件。这是确保dut不受其他外部测试系统干扰影响的方法，这将扭曲测量结果，并防止其他外部仪器或测试系统受到无线电接口测试的影响。为了满足这些要求，一个测试箱必须提供高的屏蔽效能，良好的天线耦合系数，以及可重复的结果的坚固的机械设计。
为满足自动生产线的要求，研发了R&S TS7121射频测试箱。这些包括长期使用寿命，坚固的设计和自动打开和关闭射频盒。高屏蔽效能在宽频率范围、射频测试盒子上执行测试模块和无线接口的设备按照多种标准如ISM、GSM / CDMA2000®/ WCDMA,蓝牙®,ZigBee®,WiMAX™,WIFI和LTE。
