EMCtools光纖總線CAN FD
品牌：EMCtools
類型：光纖總線Microbox
型號(hào)：CAN FD
德國EMCTOOLS的用于總線信號(hào)轉(zhuǎn)換的光電模塊（FO），包括兩個(gè)模塊，分別安置于EMC實(shí)驗(yàn)室（電波暗室及屏蔽室）內(nèi)部和外部。用于傳輸待測(cè)物（DUT）和輔助設(shè)備之間的總線信號(hào)。這種FO把總線電信號(hào)轉(zhuǎn)換后，以光信號(hào)的形式，穿過EMC實(shí)驗(yàn)室。如果使用電纜在實(shí)驗(yàn)室內(nèi)外傳輸總線信號(hào)，電纜穿過EMC實(shí)驗(yàn)室的屏蔽鋼板時(shí)，會(huì)導(dǎo)致的屏蔽效被破壞。而這種光信號(hào)的傳輸方式避免了屏蔽效能被破壞，這樣保證的EMC實(shí)驗(yàn)室在EMC測(cè)試過程中，能在EMC實(shí)驗(yàn)室內(nèi)外正常的傳輸總線信號(hào)。此類FO在使用過程中，可以滿足汽車EMC測(cè)試標(biāo)準(zhǔn)對(duì)于DUT的要求。并以其*
佳的EMC性能和極高的通信成功性能，大大節(jié)省了用戶調(diào)試過程的時(shí)間。這使EMC測(cè)試得以高效進(jìn)行。因?yàn)檫@種FO主要應(yīng)用于汽車EMC領(lǐng)域，需要其具備如下性能：EMI性能——滿足CISPR12 / CISPR25的測(cè)試性能要求EMS性能——滿足ISO11451 / ISO11452的測(cè)試性能要求ESD性能——部分型號(hào)配合ESD保護(hù)器，可滿足ISO10605的測(cè)試性能要求各大主機(jī)廠車輛EMC測(cè)試標(biāo)準(zhǔn)（引用以上標(biāo)準(zhǔn)）。
