Abstract

The invention discloses radiation property testing method and system. The method comprises the following steps of: constructing a notebook computer placing method and a wireless data terminal testing model of the notebook computer; establishing a spheric coordinate system by using an antenna of the wireless data terminal as the origin point, and selecting a testing point in the spheric coordinate system; placing the testing model in a full dark wave chamber to enable the wireless data terminal to work in a data mode, utilizing the measuring antenna to collect the total radiation power in the testing point of the spheric coordinate system, and then obtaining the total radiation power of the wireless data terminal. By using the technical scheme, the invention can truly reflect the influence of the original element coupling of the notebook computer on the space radiation property of the wireless data terminal when the wireless data terminal of the notebook computer is in the data mode, and the system has high truth and is easy to use.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular, to a radiation performance testing method and system. Background technique [0002] At present, the radio frequency performance test of wireless data terminals has attracted attention, and the test of the overall radiation performance can objectively reflect the final transmitting performance and receiving performance of the wireless data terminal. In related technologies, there are mainly two methods to test the radiation performance of wireless data terminals: one is to determine the radiation performance of the antenna, and focus on the antenna's radiation parameters such as the gain, efficiency, and pattern of the wireless data terminal antenna. To test the radiation performance of wireless data terminals, this test method is called passive testing, and the other is to test the spatial radio frequency performance of wireless data terminals such as radiated power in a specif...
