Embodiment Construction

[0029] In order to make the objectives, technical solutions and advantages of the present invention more clear and definite, the following examples are given to further describe the present invention in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] A kind of terminal antenna TRP quick test method, is used for testing terminal antenna radiation performance in OTA darkroom test, comprises the steps:

[0031] S10, place the terminal on the darkroom turntable, connect the base station emulator through the antenna, the base station emulator transmits the signal to the terminal through the darkroom measurement antenna, and the receiving system of the terminal receives and decodes the transmit signal of the base station emulator, and the base station emulator It should be noted that the working channel of the base station emulator is preferably set to be the bes...

Abstract

A terminal antenna total radiated power (TRP) fast testing method is used for testing radiation performance of a terminal antenna in an over-the-air (OTA) darkroom test. A terminal placed on a darkroom turntable takes every antenna polarization direction with a certain theta angle and a certain phi angle as a testing point to test the power of a certain channel so as to obtain the effective radiated power (ERP) of a corresponding point and then generates a transmitting power strength directional diagram. The antenna polarization direction at the best theta angle and the best phi angle is sought according to the transmitting power strength directional diagram and the ERP<CH1> of a channel to be tested is measured. All the ERP<CH1> values are subjected to integrated computation and the TRP of the terminal antenna is obtained. The method simplifies the generating process of the ERP in two antenna polarization directions at each theta angle and each phi angle of the turntable, corrects the test result to enable the test result to be more accurate, promotes the measuring efficiency of the TRP due to simplifying of the algorithm and reduces testing cost.

Description

technical field [0001] The invention relates to a mobile communication terminal, in particular to a terminal antenna TRP fast testing method. Background technique [0002] At present, more and more attention is paid to the radiation performance test of the mobile phone in the radio frequency performance test of the wireless terminal. This radiation performance reflects the final transmission and reception performance of the mobile phone. There are mainly two methods in the existing technology to investigate the radiation performance of the mobile phone. One is to judge from the radiation performance of the antenna, which is a more traditional antenna test method, which is called passive test, and the other is to test the radiation power and receiving sensitivity of the mobile phone in a specific microwave anechoic chamber, which is called active test. The OTA (Over The Air) test is an active test. The basic workflow of the existing OTA darkroom test system to test the antenn...
