Abstract

The invention discloses a system for testing the receiving sensitivity of a data terminal. The system comprises a muffling microwave darkroom, test control equipment, a tested data terminal and a universal serial bus (USB) cable, wherein the test control equipment is put on a ground in the muffling microwave darkroom, covered by a wave absorption material and used for supplying power to the tested data terminal and controlling a working state and a working mode of the tested data terminal; the USB cable is a metal core shielding cable and used for connecting the test control equipment and the tested data terminal; and the total isotropic sensitivity (TIS) of the tested data terminal is measured. The invention also discloses a method for testing the receiving sensitivity of the data terminal. By adopting the system and the method, the influence of the test control equipment on a test result can be avoided, so that the test result is reliable; and therefore, the performance of different types of data terminals can be fairly and effectively compared according to the test result.

Description

technical field [0001] The invention relates to testing and performance evaluation technology of wireless communication products, in particular to a testing system and method for receiving sensitivity of a data terminal. Background technique [0002] With the rapid development of radio technology, there are more and more types of wireless communication products, including: voice and data wireless handheld terminals, and various notebook computers with built-in or external wireless connection devices. Good receiving performance is the key to ensure the communication quality of various wireless communication products. Therefore, it is necessary to use space radio frequency performance test and measure the quality of wireless communication products through performance test indicators. Among them, the total isotropic receiving sensitivity (TIS, Total Isotropic Sensitivity) is the most important index reflecting the actual receiving signal performance of the device under test (DU...
