SAR, tseem hu ua Specific Absorption Rate, yog hais txog cov electromagnetic nthwv dej absorbed los yog noj ib chav tsev loj ntawm tib neeg cov ntaub so ntswg. Chav tsev yog W / Kg lossis mw / g. Nws hais txog qhov ntsuas lub zog nqus ntawm tib neeg lub cev thaum raug xov tooj cua zaus electromagnetic teb.
Kev kuaj SAR feem ntau yog tsom rau cov khoom siv wireless nrog cov kav hlau txais xov tsis pub dhau 20cm ntawm tib neeg lub cev. Nws yog siv los tiv thaiv peb ntawm cov khoom siv wireless uas tshaj li RF kis tus nqi. Tsis yog txhua lub kav hlau txais xov xa xov hluav taws xob tsis pub dhau 20cm ntawm tib neeg lub cev yuav tsum tau kuaj SAR. Txhua lub teb chaws muaj lwm txoj kev ntsuas hu ua MPE kev ntsuam xyuas, raws li cov khoom uas ua tau raws li cov xwm txheej saum toj no tab sis muaj hwj chim qis dua.
Kev xeem SAR thiab lub sijhawm ua haujlwm:
Kev xeem SAR feem ntau muaj peb ntu: kev lees paub hauv lub koom haum, kev siv tau zoo, thiab kev xeem DUT. Feem ntau hais lus, cov neeg ua haujlwm muag khoom yuav ntsuas lub sijhawm kuaj ua ntej raws li cov khoom tshwj xeeb. Thiab zaus. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tau xav txog lub sij hawm ua cov ntawv xeem thiab ntawv pov thawj. Qhov kev sim ntau zaus yog yuav tsum tau, lub sij hawm sim yuav ntev dua.
BTF Testing Lab muaj SAR cov cuab yeej kuaj xyuas uas tuaj yeem ua tau raws li qhov kev xav tau ntawm cov neeg siv khoom, suav nrog cov kev xav tau kev sim sai. Tsis tas li ntawd, qhov ntsuas zaus npog 30MHz-6GHz, yuav luag npog thiab tuaj yeem kuaj txhua yam khoom hauv khw. Tshwj xeeb tshaj yog rau qhov nrov nrov ntawm 5G rau Wi-nkaus cov khoom thiab tsawg zaus 136-174MHz cov khoom lag luam hauv kev ua lag luam, Xinheng Testing tuaj yeem pab cov neeg siv khoom daws teeb meem kev sim thiab ntawv pov thawj zoo, ua kom cov khoom lag luam zoo nkag mus rau hauv kev lag luam thoob ntiaj teb.
Cov qauv thiab cov cai:
Ntau lub teb chaws thiab cov khoom lag luam muaj qhov sib txawv rau SAR txwv thiab ntsuas zaus.
