EMCtools光纖總線CAN FD
品牌：EMCtools
類型：光纖總線Microbox
型號：CAN FD
德國EMCTOOLS的用于總線信號轉(zhuǎn)換的光電模塊（FO），包括兩個模塊，分別安置于EMC實驗室（電波暗室及屏蔽室）內(nèi)部和外部。用于傳輸待測物（DUT）和輔助設(shè)備之間的總線信號。這種FO把總線電信號轉(zhuǎn)換后，以光信號的形式，穿過EMC實驗室。如果使用電纜在實驗室內(nèi)外傳輸總線信號，電纜穿過EMC實驗室的屏蔽鋼板時，會導(dǎo)致的屏蔽效被破壞。而這種光信號的傳輸方式避免了屏蔽效能被破壞，這樣保證的EMC實驗室在EMC測試過程中，能在EMC實驗室內(nèi)外正常的傳輸總線信號。此類FO在使用過程中，可以滿足汽車EMC測試標準對于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)試過程的時間。這使EMC測試得以高效進行。因為這種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的測試性能要求EMS性能——滿足ISO11451 / ISO11452的測試性能要求ESD性能——部分型號配合ESD保護器，可滿足ISO10605的測試性能要求各大主機廠車輛EMC測試標準（引用以上標準）。
