A shielding box is a metal body made of conductive or magnetic materials in various shapes, which limits electromagnetic capabilities to a certain spatial range and is used to suppress radiation interference. And it is a device that processes conduction and radiation to provide a non-interference testing environment for the tested wireless communication equipment. According to different testing requirements, it is divided into manual shielding boxes, pneumatic shielding boxes, and fully automatic shielding boxes. (1) Manual shielding box: Easy to operate, testing devices such as mobile phones, laptops, and PADs all have corresponding sizes of equipment. Suitable for research and development, testing, certification, and other institutions. (2) Multiple pneumatic shielding boxes: used in production testing to improve testing efficiency and reduce operator fatigue. Test devices such as mobile phones, laptops, and PADs have corresponding sizes. (3) Fully automatic shielding box: Control the testing shielding box according to communication instructions through the international standard RS-232 interface to complete the entire testing process. It is generally used for small RF modules and large-scale production lines to improve production efficiency. According to the different shielding frequencies of product testing, the shielding boxes are further divided into ultra-low frequency shielding boxes (0-300M), low-frequency shielding boxes (300-800M), intermediate frequency shielding boxes (800-2.4G), and high-frequency shielding boxes (2.4G-5.8G). So when searching for a shielding box, it is important to choose the most suitable shielding box according to your own needs
