主要功能及特色

COMPACT– The device under test (DUT) antenna size and operating frequency dictates the far-field distance requirement for over-the-air (OTA) testing and drives the chamber dimensions. At mmWave frequencies, the far-field dimension is small enough so that MilliBox chambers can comfortably fit on a lab benchtop.The deck has multiple measurement positions with 8cm (3”) passthrough holes for direct wiring without connector ports. Conveniently, measurement instruments can be placed just below the MilliBox chamber deck, which reduces the RF coax length and cable loss. The horn post and the DUT positioners are placed on opposite ends of the chamber deck. Access to the inside is granted through the front doors that close to seal the chamber during test.
MODULAR– MilliBox chambers are built of modular construction components allowing the creation of several configurations to address differing needs. The MBX3x series of 80cm (30”) cubic modules. The chamber size is selected to satisfy the far-field requirements, and extension “cubes” can be added if the need arises.

紧凑化——被测设备 (DUT) 的天线尺寸和工作频率决定了无线 (OTA) 测试的远场距离要求，并决定了暗室的尺寸。在毫米波频率下，远场尺寸足够小，因此 MilliBox 暗室可以轻松放置在实验室台面上。该平台设有多个测量位置，并配有 8 厘米（3 英寸）通孔，可直接接线，无需连接器端口。测量仪器可方便地放置在 MilliBox 暗室平台正下方，从而减少射频同轴电缆长度和电缆损耗。喇叭柱和DUT定位器分别位于暗室平台的两端。测试期间，可通过关闭的前门进入暗室内部，从而密封暗室。

模块化—— MilliBox 暗室采用模块化组件构建，可根据不同需求创建多种配置。MBX3x 系列由 80 厘米（30 英寸）立方体模块组成。暗室尺寸的选择取决于测试的远场需求，并且可以根据需要稍后扩展。
