SAR 測試
MET實驗室具有的認證資質和豐富的經驗能夠高效和經濟的執行高達6GHz的美國，加拿大和歐洲（SAR）測試。
MET使用DASY4
MET使用DASY4
MET的SAR設備完全配置了一個Schmid＆Partner工程公司（SPEAG™）DASY專業系統，利用RX 90機械臂進行擴展。此外，我們的DASY系統有多個雙模SAM模體和平面模體，允許快速測試周轉時間 。DASY能夠針對頭部和身體佩戴設備的所有全球SAR標準評估產品。
MET測試一系列產品，例如蜂窩/ PCS GSM / DCS CDMA / GMSK / TDMA / AMPS電話，PDA，筆記本電腦，面對面設備，W-LAN（2.4GHz和5GHz）
結合SAR測試，MET還對固定和/或移動應用執行最大允許曝光（MPE）評估。這些評估是在準備在距離最終用戶> 20cm的距離處使用的輻射結構上執行的。我們的測試的典型設備是 在UHF和VHF頻帶中工作的車載天線。

什麼是SAR測試？
SAR測試是暴露於RF場的生物對象內吸收的電磁能量的幅度和分佈的射頻（RF）劑量測定量化。
這些水平表示為瓦/千克（W / kg）。國際監管機構要求對大多數便攜式和移動無線技術進行SAR評估。
可以影響SAR的參數包括：
無線電服務的類型（蜂窩，PCS，LMR，WLAN等）
調製類型（CDMA，GMSK，TDMA，AMPS等）
對人的身體取向（持有耳，持有面，帶夾，搭扣等）
射頻功率水平（瓦特或mW）
變送器，天線（抽出/收回）或附件（夾子，電池等）
FCC將廣泛的獨立操作的便攜式發射器分類為SAR測試的潛在候選者。例如，便攜式計算機可能需要SAR測試。戴在皮帶上的手機，傳呼機和其他設備也可能需要SAR測試。 天線和輻射結構距離人不到20厘米，除了四肢（手，手腕，腳和腳踝），並且根據設備的頻率和閾值水平，可能就需要SAR測試。
