Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a radio frequency interference testing system, method and device, and a radio frequency testing instrument. Background technique [0002] In wireless systems, the interference of wireless channels can cause many problems for users. The identification and mitigation of interference is extremely important for all wireless systems to function properly. [0003] In the related art, when testing the radio frequency interference of the mobile phone, the mobile phone is placed on the coupling plate of the shielding box. The surface of the coupling plate of the shielding box is a plane. After the mobile phone under test is placed on this plane, it will block the antenna of the mobile phone, and the resonance point of the antenna will shift, making it difficult to detect interference signals. Contents of the invention [0004] The present invention aims to solve one of th...
