A method for calibrating 3g network card

Abstract

The invention relates to the field of 3G (3rd Generation) telecommunications, in particular to a system for calibrating a 3G network card and a calibration method thereof. The system comprises a PC (Personal Computer), an Agilent 8960 general-purpose tester, a stabilized voltage supply and a plate clamp to be tested, wherein the 3G network card is fixed on the plate clamp to be tested; the Agilent 8960 general-purpose tester is connected to the PC through a general purpose interface bus; the PC is connected with the plate clamp to be tested through a USB (Universal Serial Bus) interface wire; the stabilized voltage supply is used for supplying a power supply for the plate clamp to be tested; the Agilent 8960 general-purpose tester is connected with the 3G network card through a radio frequency line. The automation of 3G network card production is realized, the interference of manual work on the testing environment is reduced, the error in operation of man-made validation is avoided, the test result for the radio frequency is prevented from being influenced by the accuracy of circuit attenuation, the workload of operators is reduced, and the production efficiency and degree of accuracy are improved.

Description

technical field [0001] The invention relates to the field of 3G communication, in particular to a system for calibrating a 3G network card and a calibrating method thereof. Background technique [0002] The 3G network card is a widely used Internet medium for wireless wide-area communication networks. At present, my country has three network standards: China Mobile's td-scdma, China Telecom's CDMA2000, and China Unicom's WCDMA. Therefore, common wireless network cards include CDMA2000 wireless network cards and TD and WCDMA wireless network cards. [0003] With the development of society and technology, 3G technology has entered people's lives more and more widely. As an Internet medium, 3G network card has also become a common item in people's daily life. Strong market demand requires corresponding productivity to meet the requirements. However, the production of 3G network cards is not easy. During the production process of 3G network cards, it is necessary to calibrate ...
