Consistency testing system and method of communication terminals

Abstract

The invention discloses a consistency testing system and method of communication terminals. The testing system comprises communication terminals to be tested, a computer, four testing instruments, namely an integrated tester for consistency testing, a spectrometer, an analog signal source and a vector signal source, and a radio frequency control cabinet, wherein each testing instrument is connected with a controllable radio frequency channel of the radio frequency control cabinet by a radio frequency line and further connected with the communication terminals to be tested by the controllable radio frequency channel and is also connected with the computer by a busbar. According to the invention, the radio frequency control cabinet is used for automatically controlling a plurality of testing instruments to be connected with the communication terminals to be tested, so that the consistency testing of the communication terminals can be conveniently realized by using the traditional testing instruments, the testing performance is improved and the testing cost is reduced.

Description

technical field [0001] The invention relates to communication terminal testing technology, in particular to a communication terminal consistency testing system and testing method. Background technique [0002] In order to ensure product quality, communication terminals need to be tested on relevant performance indicators on the production line before leaving the factory. For 3G communication terminals, they need to meet the specifications of 3GPP before leaving the factory. Therefore, they need to be tested for conformance to realize detailed and comprehensive tests for their transmitter characteristics, receiver characteristics, and data services. [0003] At present, the production line of general communication terminals can only carry out RF (radio frequency) calibration and testing of general performance indicators for communication terminals, and cannot test other indicators required in 3GPP specifications. In order to complete the conformance test of the communication...

AI Technical Summary

Problems solved by technology

[0003] At present, the production line of general communication terminals can only test the RF (radio frequency) calibration and general performance indicators for communication terminals, and cannot test other indicators required in the 3GPP specifications

In order to complete the conformance test of the communication terminal, the manufacturer of the communication terminal needs to entrust the certification laboratory to conduct the test. Not only the test cost is expensive, but also the test speed is limited by the test progress of the certification laboratory, and the test efficiency is low

Moreover, the interaction between testers and designers is poor, and problems in the test cannot be discovered and corrected in time, and the real-time performance is low
