Problems solved by technology

[0005] However, this type of fast measurement system is a test mode that directly transmits energy from the wireless terminal to the receiving antenna, and can only test the energy radiated from one or several solid angle directions, which makes the test data relatively one-sided and affects the accuracy of the test results. and stability

Abstract

The application discloses a testing system for a wireless terminal. The system includes: a shielded box; the device under test, which is a wireless terminal; the test antenna, used for wireless communication with the device under test; It is used to reflect and aggregate the wireless signal emitted by the DUT into a spherical area with the test antenna as the center and half the wavelength corresponding to the lowest test frequency as the radius; the rotating mechanism is used to carry the DUT and adjust The azimuth angle of the tested part and the pitch angle of the tested part relative to the aggregation mechanism; the controller is used to control the rotation mechanism so that the tested part is adjusted to the target position, wherein the target position means that the tested part is in the shielding box The position where the energy distribution of the transmitted wireless signal is strongest. The test system adjusts the attitude of the tested part through the rotating mechanism, and realizes the test of the energy emitted by the tested part in all directions, thereby improving the accuracy and stability of the test results.

Description

technical field [0001] The present application relates to the communication field, in particular to a wireless terminal testing system. Background technique [0002] Wireless terminal products need product testing in both R&D and production. The performance of wireless terminal antennas is an important indicator of wireless terminal products. Therefore, the performance test of wireless terminal antennas is related to the product development cycle and product quality. With the development of wireless terminal technology and the increase of market demand, new requirements are put forward for test efficiency and test cost. [0003] Compared with the passive test, the OTA (Over-The-Air, space port communication performance) test comprehensively inspects the overall antenna performance of the wireless terminal in the simulated actual use of the wireless terminal. The OTA test measures the total radiated power TRP (Total Radiated Power) of the terminal by testing the energy radia...
