Quick parallel radio frequency test system and test method for mobile terminals

Abstract

The invention relates to a mobile terminal parallel radio frequency testing device, which comprises a CDMA signal resource, a frequency spectrum analyzer and a switch matrix connected to the CDMA signal resource and the frequency spectrum analyzer; a testing control unit via the GPIB connecting the CDMA signal resource, the frequency spectrum analyzer, and the switch matrix; and a communication direct current power resource connected to the CDMA signal resource, the frequency spectrum analyzer and the tested mobile terminal to supply power for them. The invention uses the dynamic power testing technique based on the single point trigger and the mobile terminal sender, to realize the parallel correction test. The invention can correct and test the radio frequency property of the sender and the receiver of CDMA mobile terminal to improve the testing speed and improve the utilization of device.

Description

technical field The present invention relates to the test of CDMA mobile communication terminal in the field of mobile communication, in particular to the calibration test system and test method of the radio frequency performance parameters of the receiver and transmitter of the mobile terminal in the CDMA communication network. Background technique The radio frequency performance index of the CDMA mobile terminal is mainly controlled through the software and hardware of the mobile terminal itself. In actual production, due to the discreteness of the parameters of the RF circuit components of the mobile terminal, the RF performance parameters of each mobile terminal cannot meet the ideal design requirements. Therefore, in order to ensure that the RF performance of each mobile terminal can meet the design index requirements, it is necessary to perform RF test and adjustment on each mobile terminal during the production process, so as to ensure that the RF performance of each...
