Abstract

The invention relates to a multi-mode radio equipment electromagnetic disturbance test system, belonging to the electromagnetic compatible test technique field of wireless communication products, which comprises: a wireless communication base station simulator, a receiver, a wave trapper unit, a system console, a radio frequency switcher, two antennas and a plurality of cables connecting the elements, wherein the system console is connected with the wireless communication base station simulator via a GPIB cable, the receiver is connected with the radio frequency switcher, each wave trapper of the wave trapper unit is connected among the switches of the radio frequency switcher, the wireless communication base station simulator is connected with a communication antenna, and the radio frequency switcher is connected with a measurement antenna. The multi-mode radio equipment electromagnetic disturbance test system can test the electromagnetic disturbance test items of multi-mode radio equipments defined in the information industry department standard YD1312.1, having high test accuracy, simple operation, high automatic degrees and low uncertainty.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic compatibility testing of wireless communication products, in particular to electromagnetic disturbance testing of multi-mode radio equipment. Background technique [0002] With the development of wireless communication technology, various types of multi-mode radio equipment have appeared on the market, such as: products with both cellular mobile phones and wireless local area network modules, products with cellular mobile phones and Bluetooth, and dual-cellular mobile phone modules For such products, in some cases, the various wireless modules of the multi-mode cannot work at the same time. At this time, the electromagnetic disturbance test can follow the traditional electromagnetic disturbance test process to test each module separately, as long as it meets the relevant product family standards That's it. However, for wireless products that support multiple wireless modules working at th...
