The terminal device can generate a monophonic signal of a specified frequency, and can transmit the monophonic signal by using a specified receive antenna or transmit antenna of the terminal device. The terminal device has a function of transmitting the monophonic signal of the designated frequency by using any specified antenna. Therefore, a measurement system for an antenna complex number pattern of the terminal device can accurately measure a complex number pattern of each antenna of the terminal device in a manner in which the terminal device transmits the monophonic signal of the specified frequency by using each receive antenna or transmit antenna. The measurement system can further obtain an accurate measurement result when a MIMO OTA performance test is performed on the terminal device according to the complex number patterns of all the antennas of the terminal device.

A uniform turnover apparatus comprises a turnover body, a linear advance device, and a fixed base. The linear advance device has a fixed end and a movable end. The fixed end is turnably provided on the fixed base by a first fulcrum. The turnover body is movably connected with the movable end of the linear advance device by a second fulcrum. The turnover body is turnably provided on the fixed base by a third fulcrum. The first, the second, and the third fulcra form a triangle. The uniform turnover apparatus comprises a control device connected with the linear advance device. The control device acquires an actual angular velocity at which the turnover body is turned, and compares the actual angular velocity with a set angular velocity, and according to the comparison, adjusts the linear velocity of the linear advance device in real time, so that the actual angular velocity of the turnover body approximates or equals to the set angular velocity. The apparatus can make the turnover body turn placidly and effectively reduce the impact force during turning over.
