[0002] With the rapid development of science and technology and the continuous advancement of wireless technology, multi-antenna and multi-band products have gradually become mainstream in the market. However, the problem of wireless interference greatly restricts and affects the wireless performance and user experience of the products. Shielding devices are needed for radiation shielding, and the radiation shielding capability of the shielding device usually requires radiation interference testing to adjust the radiation shielding effect of the shielding device. Therefore, it is necessary to use a companion test shielding device in the radiation interference test experiment to carry out the accompanying test operation.

[0003] When the existing equipment is conducting radiation interference test, the sample often fails to pass the test because the interference value exceeds the limit due to the interference of the accompanying test sample. In actual operation, due to the limitation of the length of the connecting line or the difficulty of operation, many accompanying tests cannot be placed outside the darkroom. The test method mainly relies on professional test equipment and sites, the test convenience is relatively insufficient, and the overall operation of the test experiment is relatively complex and inconvenient, and the practical convenience is relatively insufficient. For this reason, we propose a accompanying test shielding device for radiation emission test to solve the above problems. Utility Model Content
