BTF Testing Lab Electromagnetic Compatibility (EMC) qhia

piav qhia luv luv:

Electromagnetic compatibility (EMC) yog hais txog lub peev xwm ntawm lub cuab yeej lossis lub kaw lus ua haujlwm raws li nws qhov chaw nyob hauv electromagnetic tsis ua rau muaj kev cuam tshuam tsis zoo ntawm electromagnetic cuam tshuam rau txhua yam khoom siv hauv nws ib puag ncig. Yog li ntawd, EMC suav nrog ob qhov yuav tsum tau ua: Ntawm ib sab, nws txhais tau hais tias qhov cuam tshuam ntawm electromagnetic cuam tshuam los ntawm cov khoom siv rau ib puag ncig hauv cov txheej txheem ua haujlwm ib txwm tsis tuaj yeem tshaj qhov txwv; Ntawm qhov tod tes, nws txhais tau hais tias cov cuab yeej muaj qee qhov kev tiv thaiv ntawm electromagnetic cuam tshuam hauv ib puag ncig, uas yog, electromagnetic rhiab heev.

Taw qhia rau Bluetooth Technology

EMC tus qauv txheej txheem txheej txheem ntawm cov koom haum thoob ntiaj teb feem ntau txais cov txheej txheem kev faib tawm ntawm International Electrotechnical Commission (IEC), uas tau muab faib ua peb pawg: cov qauv qauv, cov qauv dav dav, thiab cov qauv khoom. Ntawm lawv, cov qauv khoom tau muab faib ntxiv rau hauv cov qauv khoom lag luam thiab cov qauv khoom tshwj xeeb. Txhua hom qauv muaj xws li kev cuam tshuam thiab kev cuam tshuam cov qauv. EMC cov qauv raug coj los ua raws li qhov kev txiav txim ntawm "cov qauv khoom tshwj xeeb → cov qauv khoom → cov qauv dav dav".
