Menene gwajin SAR?

SAR, wanda kuma aka sani da Specific Absorption Rate, yana nufin raƙuman ruwa na lantarki da ake sha ko cinyewa a kowace naúrar nama na ɗan adam. Naúrar ita ce W/Kg ko mw/g. Yana nufin ma'aunin ɗaukar kuzari na jikin ɗan adam lokacin da aka fallasa su zuwa filayen lantarki na mitar rediyo.
Gwajin SAR yana nufin samfuran mara waya tare da eriya tsakanin nisa na 20cm daga jikin mutum. Ana amfani da shi don kare mu daga na'urorin mara waya waɗanda suka wuce ƙimar watsa RF. Ba duk eriyar watsa mara waya ba tsakanin nisa na 20cm daga jikin mutum yana buƙatar gwajin SAR. Kowace ƙasa tana da wata hanyar gwaji mai suna MPE kimantawa, dangane da samfuran da suka cika sharuddan da ke sama amma suna da ƙaramin ƙarfi.

Shirin gwajin SAR da lokacin jagora:
Gwajin SAR ya ƙunshi sassa uku: ingantacciyar ƙungiya, ingantaccen tsarin, da gwajin DUT. Gabaɗaya magana, ma'aikatan tallace-tallace za su kimanta lokacin jagoran gwaji bisa ƙayyadaddun samfur. Da kuma mita. Bugu da ƙari, wajibi ne a yi la'akari da lokacin jagora don rahotannin gwaji da takaddun shaida. Yawancin gwajin da ake buƙata akai-akai, za a buƙaci tsawon lokacin gwaji.
Gano Xinheng yana da kayan gwajin SAR waɗanda zasu iya biyan buƙatun gwaji na abokan ciniki, gami da buƙatun gwajin aikin gaggawa. Bugu da kari, mitar gwaji ta rufe 30MHz-6GHz, kusan rufewa da iya gwada duk samfuran kan kasuwa. Musamman don saurin yaɗa 5G don samfuran Wi-Fi da ƙananan samfuran 136-174MHz a kasuwa, Gwajin Xinheng na iya taimaka wa abokan ciniki yadda ya kamata don magance matsalolin gwaji da takaddun shaida, ba da damar samfuran su shiga kasuwannin duniya cikin sauƙi.
