Embodiment Construction

[0060] A TIS testing method for a WCDMA mobile terminal provided by the present invention. In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] Such as figure 1 As shown, it is a schematic structural diagram of a typical OTA (Over The Air: test through air conduction) darkroom 100 , and a WCDMA mobile terminal (device under test) 200 is placed on a turntable 110 . The turntable 110 has two rotation axes, which are respectively named Theta axis (θ axis) and Phi axis (φ axis). The transceiver antenna 120 of the OTA darkroom 100 can have two directions, horizontal and vertical.

Abstract

Disclosed is a WCDMA mobile terminal TIS test method. Since it uses the method of quickly locating the sensitivity of any location under radiation by a CPICH RSCP value corresponding to the sensitivity conducted by a WCDMA terminal, the WCDMA mobile terminal TIS test method provided in the present invention can improve the sensitivity search time of each angle of the WCDMA TIS test, thus improving the entire measurement speed of the WCDMA TIS. Furthermore, using the method of quickly locating the sensitivity of any location under radiation by a CPICH RSCP value corresponding to the sensitivity of any point in a WCDMA terminal radiation mode can improve the sensitivity search time of each angle of the TIS test, thus improving the TIS test efficiency of the WCDMA mobile terminal.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a TIS test method for a WCDMA mobile terminal. Background technique [0002] As we all know, the current WCDMA mobile terminal OTA (Over The Air: test through air conduction) test system requires huge investment and complicated test methods. The OTA test (test conducted through air conduction) includes two main test indicators: Total Radiated Power (TRP: Total Radiated Power) and Total Isotropic Sensitivity (TIS: Total Isotropic Sensitivity). Among them, the TIS test takes the longest time, and a comprehensive single-channel TIS test needs about 1 hour of test time. Compared with the total investment of several million RMB in the OTA test system, the greater the test time, the greater the cost. At the same time, due to the huge cost, it is impossible for testing and certification laboratories or R&D institutions to build many OTA laboratories. Therefore, the OTA ...
