Problems solved by technology

[0004] However, the measurement speed of this system is slow, and because the distance between the test antenna and the DUT is required to be greater than the far-field distance, so that the DUT is exposed to the plane wave irradiation of the test antenna, this leads to a bulky measurement system. Manufacturing High cost and small scope of application

Abstract

The invention discloses a wireless terminal test system and a control method used for the wireless terminal test system. The system comprises a tested member which is a wireless terminal; a reflecting surface which is used for total reflection of wireless signals emitted by the wireless terminal; a test antenna which is used for receiving the wireless signals; and an absorbing screen, wherein the positional relation of the tested member, the test antenna and the reflecting surface is corresponding to the same ellipsoidal surface, the tested member and the test antenna are respectively arranged on the two focuses of the same ellipsoidal surface and the reflecting surface is arranged on the ellipsoidal surface, and the absorbing screen is arranged on a straight line between the tested member and the test antenna. According to the test system, the sum of the power of the wireless signals of multiple directions can be tested in one time, the structure of the test system is simplified, test speed is faster and multiple times of repeated test operation can be avoided so that the test system has the advantages of being low in test result repeatability error, stable in test result, high in test efficiency and low in cost and the test system is particularly suitable for the research and development and production aspects of the wireless performance of the wireless terminal.

Description

technical field [0001] The present invention relates to the technical field of wireless terminals, in particular to a testing system for wireless terminals and a control method therefor. Background technique [0002] In the radiation performance test of wireless terminals, it is necessary to measure the magnitude of radiation signals in multiple directions and the magnitude of receiving sensitivity in multiple radiation directions, and obtain the total radiation power and total radiation sensitivity through mathematical calculations. Since the antenna of a mobile wireless communication terminal is usually not a directional antenna, but radiates in all directions in space, when testing the wireless performance of a mobile terminal, the basic idea is to place the device under test at the center of a sphere, and use the test The antenna measures the strength of the signal at multiple positions on the spherical surface, and calculates the total radiation intensity after obtainin...
