SAR, eo hape e tsejoang e le Specific Absorption Rate, e bua ka maqhubu a motlakase a monyang kapa a jeoang ka yuniti ea boima ba lisele tsa motho. Yuniti ke W/Kg kapa mw/g. E bua ka sekhahla sa ho monya matla a 'mele oa motho ha o pepesetsoa masimong a radio frequency electromagnetic.
Teko ea SAR e etselitsoe haholo lihlahisoa tse se nang mohala tse nang le manakana a bohole ba 20cm ho tloha 'meleng oa motho. E sebelisoa ho re sireletsa lisebelisoa tsa mohala tse fetang boleng ba phetisetso ea RF. Ha se li-antenna tsohle tsa phetiso ea waelese tse bohole ba 20cm ho tloha 'meleng oa motho tse hlokang tlhahlobo ea SAR. Naha ka 'ngoe e na le mokhoa o mong oa tlhahlobo o bitsoang tlhahlobo ea MPE, o ipapisitse le lihlahisoa tse fihlelang maemo a kaholimo empa matla a tlase.
Lenaneo la tlhahlobo ea SAR le nako ea ho etella pele:
Teko ea SAR haholo-holo e na le likarolo tse tharo: netefatso ea mokhatlo, netefatso ea sistimi, le tlhahlobo ea DUT. Ka kakaretso, barekisi ba tla lekola nako ea ho etsa liteko ho latela litlhaloso tsa sehlahisoa. Le khafetsa. Ntle le moo, hoa hlokahala ho nahana ka nako ea pele ea litlaleho tsa liteko le setifikeiti. Ha ho hlokahala tlhahlobo khafetsa, nako ea teko e tla hlokahala nako e telele.
BTF Testing Lab e na le lisebelisoa tsa tlhahlobo tsa SAR tse ka fihlelang litlhoko tsa tlhahlobo tsa bareki, ho kenyeletsoa le litlhoko tse potlakileng tsa tlhahlobo ea projeke. Ntle le moo, maqhubu a liteko a akaretsa 30MHz-6GHz, e batlang e koahela ebile e khona ho leka lihlahisoa tsohle tse marakeng. Haholo-holo bakeng sa phatlalatso e potlakileng ea 5G bakeng sa lihlahisoa tsa Wi Fi le lihlahisoa tse tlase tsa 136-174MHz 'marakeng, Teko ea Xinheng e ka thusa bareki ka katleho ho rarolla mathata a tlhahlobo le setifikeiti, ho nolofalletsa lihlahisoa ho kena 'marakeng oa machabeng.
Maemo le melaoana:
Linaha le lihlahisoa tse fapaneng li na le litlhoko tse fapaneng bakeng sa meeli ea SAR le maqhubu a tlhahlobo.
