Abstract

The invention discloses a wireless terminal test system and a control method thereof. The system comprises a tested piece, a reflecting surface, a rotating mechanism, a test antenna, and an absorbing screen, wherein the tested piece is the wireless terminal; the reflecting surface is used for carrying out total reflection on wireless signals transmitted by the tested piece; the rotating mechanism is used for fixing the tested piece and driving the tested piece to rotate to enable the wireless signals transmitted by the wireless terminal in multiple directions to be sequentially shot to the reflecting surface; the test antenna is used for receiving the wireless signals; the position relation among the tested piece, the test antenna and the reflecting surface is corresponding to the same ellipsoid; the tested piece and the test antenna are arranged at two focal points of the same ellipsoid respectively; the reflecting surface is arranged on the ellipsoid; and the absorbing screen is arranged on the straight line between the tested piece and the test antenna. When the wireless terminal test system of the embodiment of the invention is applied, the system structure is simplified, multiple times of repeated test operation can be avoided, the test result repeatability error is small, the test result is stable, the test efficiency is high, and the cost is low.

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...
