Veneer radio frequency test system for dual-mode single-standby mobile terminal

Abstract

The invention provides a single-board RF testing system of double-mode single-standby terminal, which includes: a testing clamp for fixing single-board; a power divider of one dividing into two, which is equipped on the testing clamp and is connected with an integrated testing instrument, for converting between the RF index calibration and final test under various types of systems; an integrated testing instrument, which is connected with single-board testing interface through the power divider of one dividing into two and the testing clamp, for carrying out RF index calibration and final test of the single-board with every kinds of modes; a power, which is connected to the testing clamp and a computer, for supplying power for the single-board through the computer control and the testing clamp; and a computer, which is used for connecting the integrated testing instrument group to the power supply, and controlling operation of the integrated testing instrument group and the power supply of the power to the single-board, and connecting to the testing clamp, thereby transmitting data to the single-board through the testing clamp. Thereby, the automation of TD-SCDMA / GSM double-mode single-standby mobile terminal RF testing process is realized, and the testing time is shortened, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a system for performing radio frequency test on a single board of a TD-SCDMA / GSM dual-mode single-standby mobile terminal. Background technique [0002] The single board of the mobile terminal, also known as the mother board or main board, refers to the PCB board after SMT placement. Various chips and components have been soldered on the board, mainly including baseband chipset, radio frequency chipset, memory and multimedia processor (MP). However, it does not include peripheral components such as liquid crystal display (LCD), speakers, motors, microphones (Mic), receivers (Receiver), and cameras. In order to ensure the quality of the mobile terminal, the single board of the mobile terminal needs to be tested during production. The single board inspection of the mobile terminal in the production line is mainly divided into two parts: baseband function inspection and radio frequency calibration final inspection. Since mobile...

Problems solved by technology

[0004] 1. After testing TD-SCDMA, manually switch to GSM comprehensive tester, which takes too much time to switch instruments, increases test time, and affects production efficiency

[0005] 2. Carry out the final test of TD-SCDMA calibration first, and then go to the new station for the final test of GSM calibration after the test. Although this can increase the test time, it increases the number of stations and the production cost is relatively high.
