Based on the embodiments of the present utility model, all other embodiments obtained by the person skilled in the art based on the present utility model are included in the scope of protection of the present utility model.

The high-low temperature test of the radio frequency index of the base station is an important link of the research and development test of the base station, and for common base station types, such as 1-C and 1-H base stations, the related technology generally utilizes a temperature control camera bellows test system to test the base station. Specifically, referring to fig. 1, fig. 1 is a schematic structural diagram of a temperature control camera bellows test system in the related art. As shown in fig. 1, the temperature-controlled camera bellows test system includes: the incubator 101 and the incubator 102 are communicated with each other to realize temperature control. The radio frequency device of the base station is placed in the camera bellows 101, and is connected with the instrument by means of conducting radio frequency wires in the related art, so that radio frequency indexes of the radio frequency device at different temperatures are tested. In addition, because the temperature control camera bellows 101 test system shown in fig. 1 is a near field, a near field far field conversion system is added for the temperature control camera bellows 101 test system, and near field indexes involved in the test process are converted into far field indexes, so that radio frequency indexes of the radio frequency devices under the far field are tested.

However, for the 2-O type base station, referring to fig. 2, fig. 2 is a schematic structural diagram of the 2-O type base station in the related art, and the 2-O type base station 200 includes: the transceiver unit 201, the antenna array 202 and the wireless distribution network 203, because the antenna array 202 and the transceiver unit 201 of the base station are not detachable and cannot be connected with a conductive radio frequency line, the radio frequency device of the base station cannot test radio frequency indexes at different temperatures in a mode of conducting the radio frequency line, and only can test the radio frequency indexes in an Over The Air (OTA) test mode.

The radio frequency device to be tested may specifically be an AAU (ACTIVE ANTENNA Unit ) in a base station, and the signal receiving device 402 is a device capable of receiving and sending a signal, for example, a loudspeaker, where the signal receiving device 402 is disposed on a side, far away from the wave-transparent thermal insulation board 404, in the camera bellows 403.

Specifically, the open area of the wall of the dark box 403 may be the same as or different from the open area of the wall of the warm box 401, and if the open areas are different, the larger open area needs to be able to cover the other smaller open area, and the size of the wave-transparent insulation board 404 is able to cover the larger open area.
