產(chǎn)品簡(jiǎn)介
專為腦電類產(chǎn)品共模抑制比設(shè)計(jì)的專用測(cè)試儀，絕緣及接地設(shè)計(jì)，可量測(cè)更好的CMRR值，符合IEC80601-2-26:2019國(guó)際醫(yī)療標(biāo)準(zhǔn)性能測(cè)試要求，適用于研發(fā)、法規(guī)符合性及產(chǎn)線測(cè)試
產(chǎn)品參數(shù)
1.專為腦電類產(chǎn)品共模抑制比設(shè)計(jì)的專用測(cè)試儀，較佳的絕緣及接地設(shè)計(jì)，可量測(cè)更好的CMRR值，符合IEC80601-2-26:2019國(guó)際醫(yī)療標(biāo)準(zhǔn)性能測(cè)試要求，適用于研發(fā)、法規(guī)符合性及產(chǎn)線測(cè)試
2.針對(duì)腦電圖機(jī)的共模抑制比(CMRR)和內(nèi)部噪聲測(cè)試所設(shè)計(jì)的測(cè)試儀
3.雙層屏蔽結(jié)構(gòu)，避免內(nèi)部與外部的噪聲干擾
4.內(nèi)建校準(zhǔn)過的正弦波產(chǎn)生器，解決外接信號(hào)產(chǎn)生器電壓供應(yīng)不足問題
5.單機(jī)即可使用觸控面板調(diào)整參數(shù)后測(cè)試，連接專用軟件后可由計(jì)算機(jī)設(shè)定參數(shù)
6.CMRR標(biāo)準(zhǔn)輔助軟件簡(jiǎn)化測(cè)試步驟，點(diǎn)擊鼠標(biāo)即可完成標(biāo)準(zhǔn)需求的測(cè)試項(xiàng)目
7.提供軟件開發(fā)工具包(Software Development Kit)，用戶可自行開發(fā)客制或全自動(dòng)化測(cè)試軟件
