The invention relates to a mobile communication terminal radio frequency testing system, which belongs to the field of mobile communication terminal radio frequency test. The system comprises a comprehensive tester, a frequency spectrum analyzer, a vector signal source, a wideband signal source, a power meter, a direct current source, a temperature control box, a switch control unit and a controller thereof , and a system control platform, wherein the system control platform is connected with the controller of the switch control unit, the temperature control box, the comprehensive tester, the frequency spectrum analyzer, the vector signal source, the wideband signal source, the power meter and the direct current source respectively; and the comprehensive tester, the frequency spectrum analyzer, the vector signal source and the wideband signal source are connected with the switch control unit and a terminal to be tested respectively. The system has the advantages of simple operating flow, clear testing process, quick testing, serious processing on testing result, and good reliability and stability; in addition, the system can quickly and accurately develop a test case meeting self requirement, realize diverse and standard test, also can flexibly extend to the control on other instruments and meters, and realize flexible configuration of the system.

Description

technical field [0001] The invention belongs to the field of radio frequency testing of mobile communication terminals, and relates to radio frequency technology, communication technology, electronic measurement technology and system integration technology, in particular to the architecture design of a mobile communication terminal radio frequency testing system. technical background [0002] The radio frequency test of the mobile communication terminal is to ensure that the radio frequency performance of the terminal meets the requirements of relevant international standards. The testing process can be divided into two phases: the research and development phase and the certification phase. The certification phase test is a minimum requirement test, which is completed by a national institution or an international organization to gain market access; at present, the certification phase test, the global national structure or international organization mainly adopts a certified ...

Problems solved by technology

[0005] (1) Manually build the system: the inability to fully calibrate leads to poor test accuracy and the inability to complete complex tests

[0006] (2) Manual setting: low efficiency, poor repeatability, high error rate, unable to complete complex tests

[0007] (3) Manual processing of test results: only simple records, unable to process a large amount of data and high error rate,

[0010] (1) This type of system is only designed for the testing requirements of the certification stage, and the overall software and hardware design can only meet part of the R&D testing requirements, especially the hardware design cannot meet the comprehensive requirements of R&D testing

[0011] (2) The test program is basically fixed, cannot be changed, cannot be custo
