How to distinguish between manual shielding box, automatic shielding box, and pneumatic shielding box? The three shielding box principles are the use of various shapes of shielding body made of conductive or magnetically conductive materials to limit the electromagnetic capacity to a certain spatial range for suppression Radiated metal body. It also conducts conduction and radiation to achieve equipment that provides a non-interference test environment for the wireless communication device under test. So what's the difference between their three shielding boxes? How can they be distinguished?


如何区分手动屏蔽箱,自动屏蔽箱,气动屏蔽箱?

1. Manual shielding box


It is generally small in size and convenient to operate. Devices such as mobile phones, notebooks, and PADs have corresponding sizes. Applicable to R & D, testing, certification and other institutions.


2.Pneumatic shielding box


Pneumatic shielding boxes are generally large in volume and are mostly used in production testing, which improves testing efficiency and reduces operator fatigue. Test mobile phones, notebooks, PAD and other devices have corresponding size devices.


2.Pneumatic shielding box


Through the international standard RS-232 interface, the test shielding box is controlled according to the communication instructions to complete the entire test process. Generally, it is used for small RF modules and large-scale production lines to improve production efficiency.


How to distinguish the manual shielding box, automatic shielding box, and pneumatic shielding box from the above Safety, EMC / EMI testing, etc.
