Abstract: A test system may include a wireless test chamber with metal walls lined with pyramidal absorbers. A trapdoor may be provided in a wall opening to accommodate a robotic arm. The robotic arm may have grippers that grip a device under test or a support structure that is supporting a device under test. The robotic arm may move the device under test to a docking station for automatic battery charging during testing. When it is desired to perform wireless tests on a device under test, the robotic arm may move the device under test through the trapdoor into an interior portion of the test chamber. A turntable and movable test antenna may be used to rotate the device under test while varying angular orientations between test antenna and device under test. Emitted radiation levels can be measured using a liquid filled phantom and test probe on a robotic arm.

Abstract translation: 测试系统可以包括具有金字塔的无线测试室，内有金字塔吸收体。 可以在墙壁开口中设置一个可以容纳一个机器手臂的活门。 机器臂可以具有夹持被测设备的夹具或支撑被测设备的支撑结构。 机器人手臂可以将测试中的设备移动到对接站，以便在测试期间自动进行电池充电。 当希望在被测设备上进行无线测试时，机器人手臂可以将被测设备通过入口门移动到测试室的内部。 可以使用转盘和可动测试天线来旋转被测设备，同时改变测试天线和被测设备之间的角度定向。 发射的辐射水平可以使用机器臂上的液体填充的体模和测试探针来测量。
