快速自動(dòng)測(cè)試
自動(dòng)測(cè)試功能使得用戶無(wú)需了解更多的有關(guān)該儀器操作的細(xì)節(jié)，測(cè)試步驟變得非常簡(jiǎn)單，只需要進(jìn)入“自動(dòng)OTDR”，將光纖接入產(chǎn)品對(duì)應(yīng)OTDR端口、點(diǎn)擊【自動(dòng)測(cè)試】按鈕即可，儀器會(huì)自動(dòng)設(shè)置相應(yīng)的測(cè)試條件并給出最終測(cè)試結(jié)果，包括測(cè)試曲線和事件列表等。
自動(dòng)來(lái)光監(jiān)測(cè)及告警功能
當(dāng)OTDR測(cè)試光纖鏈路時(shí)，如果光纖中有通信光信號(hào)，會(huì)造成測(cè)試結(jié)果不準(zhǔn)確，甚至?xí)?duì)儀器內(nèi)部的探測(cè)器造成不可恢復(fù)的損壞。6426A具有對(duì)被測(cè)光纖中的通信光信號(hào)自動(dòng)監(jiān)測(cè)功能，被測(cè)光纖只要接入到產(chǎn)品光接口中，測(cè)試階段自動(dòng)感應(yīng)并監(jiān)測(cè)光纖中是否有通信光信號(hào)，一旦監(jiān)測(cè)到有光信號(hào)，將及時(shí)提示告警信息，為儀器提供及時(shí)的保護(hù)。
