I-BTF Testing Lab Electromagnetic Compatibility (EMC) isingeniso

incazelo emfushane:

I-Electromagnetic Compatibility (EMC) isho ikhono ledivayisi noma uhlelo lokusebenza ngokuhambisana nendawo yalo kazibuthe ngaphandle kokubangela ukuphazamiseka okungenakubekezelelwa kozibuthe kunoma iyiphi into esetshenziswa endaweni yayo. Ngakho-ke, i-EMC ihlanganisa izidingo ezimbili: Ngakolunye uhlangothi, kusho ukuthi ukuphazamiseka kwe-electromagnetic okukhiqizwa yimishini eya endaweni ezungezile ngenqubo evamile yokusebenza akukwazi ukweqa umkhawulo othile; Ngakolunye uhlangothi, kusho ukuthi into esetshenziswayo inezinga elithile lokungavikeleki ekuphazamiseni kazibuthe kagesi endaweni ezungezile, okungukuthi, ukuzwela kwe-electromagnetic.

Isingeniso ku-Bluetooth Technology

Uhlaka lohlelo olujwayelekile lwe-EMC lwezinhlangano eziningi zamazwe ngamazwe lwamukela uhlelo lokuhlukanisa olujwayelekile lwe-International Electrotechnical Commission (IEC), oluhlukaniswe izigaba ezintathu: amazinga ayisisekelo, amazinga ajwayelekile, namazinga omkhiqizo. Phakathi kwazo, amazinga omkhiqizo aphinde ahlukaniswe abe amazinga omkhiqizo ochungechunge kanye namazinga omkhiqizo akhethekile. Uhlobo ngalunye lwezinga lubandakanya kokubili ukugxambukela kanye namazinga okulwa nokugxambukela. Izindinganiso ze-EMC zamukelwa ngokuvumelana nokuhleleka "kwezindinganiso zomkhiqizo okhethekile → amazinga omkhiqizo → izindinganiso ezijwayelekile".
