SAR, yomwe imadziwikanso kuti Specific Absorption Rate, imatanthawuza mafunde a electromagnetic omwe amatengedwa kapena kudyedwa pa unit mass of human tissues. Chigawochi ndi W/Kg kapena mw/g. Imatanthawuza kuchuluka kwa mayamwidwe amphamvu a thupi la munthu akakumana ndi ma radio frequency electromagnetic fields.
Kuyesa kwa SAR kumayang'ana kwambiri zinthu zopanda zingwe zokhala ndi tinyanga pamtunda wa 20cm kuchokera mthupi la munthu. Amagwiritsidwa ntchito kutiteteza ku zida zopanda zingwe zomwe zimaposa mtengo wotumizira wa RF. Sikuti tinyanga zonse zotumizira ma waya opanda zingwe pamtunda wa 20cm kuchokera mthupi la munthu zimafunikira kuyezetsa kwa SAR. Dziko lililonse lili ndi njira ina yoyesera yotchedwa kuwunika kwa MPE, kutengera zinthu zomwe zimakwaniritsa zomwe zili pamwambapa koma zili ndi mphamvu zochepa.
Pulogalamu yoyesera ya SAR ndi nthawi yotsogolera:
Kuyesa kwa SAR kumakhala ndi magawo atatu: kutsimikizika kwa bungwe, kutsimikizira kachitidwe, ndi kuyesa kwa DUT. Nthawi zambiri, ogulitsa aziwunika nthawi yoyeserera potengera zomwe zagulitsidwa. Ndipo pafupipafupi. Kuphatikiza apo, ndikofunikira kuganizira nthawi yoyambira yoyeserera malipoti ndi ziphaso. Kuyesedwa pafupipafupi kumafunika, ndiye kuti nthawi yayitali yoyesera ikufunika.
BTF Testing Lab ili ndi zida zoyesera za SAR zomwe zimatha kukwaniritsa zosowa zamakasitomala, kuphatikiza zoyeserera mwachangu za polojekiti. Kuphatikiza apo, kuyezetsa pafupipafupi kumakwirira 30MHz-6GHz, pafupifupi kuphimba ndikutha kuyesa zinthu zonse pamsika. Makamaka pakutchuka kwachangu kwa 5G pazinthu za Wi Fi ndi zinthu zotsika kwambiri za 136-174MHz pamsika, Kuyesa kwa Xinheng kumatha kuthandiza makasitomala kuthana ndi zovuta zoyesa ndi ziphaso, kupangitsa kuti malonda alowe bwino pamsika wapadziko lonse lapansi.
Miyezo ndi malamulo:
Mayiko ndi malonda osiyanasiyana ali ndi zofunikira zosiyana pa malire a SAR ndi ma frequency oyesera.
