Wireless mouse EMC test items

A wireless mouse refers to a mouse that is directly connected to the host without a cable, and uses wireless technology to communicate with the computer, thereby eliminating the need for wires. Wireless communication methods are usually used, including multiple wireless technology standards such as Bluetooth, Wi-Fi (IEEE 802.11), Infrared (IrDA), ZigBee (IEEE 802.15.4), etc.

EMC test purpose

EMC testing, also known as electromagnetic compatibility testing (EMC), refers to the comprehensive identification of the size (EMI) and anti-interference (EMS) of electronic equipment at the magnetic field level. It is one of the most critical index values for product quality. Accurate measurement of compatibility test consists of test site and test equipment. The purpose of the EMC test is to measure the harm of electromagnetic radiation caused by home appliances to the body, public power grids and all other home appliances in normal operation.

Electromagnetic compatibility testing is a course for scientific research under the relatively limited indoor space, time, and frequency band resource standards, and a variety of power-consuming machines and equipment (theory also includes plants) can coexist, and will not cause degradation . It contains two parts: interference signal and electromagnetic induction sensitivity. The interference signal test is to accurately measure the size of the radio wave data signal caused by the tested machine and equipment under all normal working attitudes and to reflect the impact on the surrounding electronic products. . Electromagnetic induction susceptibility testing is to accurately measure the anti-interference ability of the equipment under test to electromagnetic induction disturbance. The interference signal mainly includes the emission point of the radiation source and the transmission emission point.
