J-BERT N4903B 的主要優(yōu)勢(shì)：使用具有極低抖動(dòng)和極短跳變時(shí)間的碼型發(fā)生器生成干凈信號(hào)，實(shí)現(xiàn)精確表征。經(jīng)過(guò)校準(zhǔn)的內(nèi)置抖動(dòng)源使您可以對(duì)接收機(jī)進(jìn)行精確的抖動(dòng)容限測(cè)試。J-BERT N4903B 是為與串行總線標(biāo)準(zhǔn)實(shí)現(xiàn)最佳匹配而設(shè)計(jì)的，具有差分 I/O、在大多數(shù)輸出上可變的電壓電平、內(nèi)置的抖動(dòng)和 ISI 功能、碼型序列發(fā)生器、參考時(shí)鐘輸出、可調(diào)諧 CDR、碼型捕獲和比特恢復(fù)模式，可對(duì)無(wú)時(shí)鐘和不確定的碼型進(jìn)行分析，因此可以顯著簡(jiǎn)化測(cè)試設(shè)置。使用 J-BERT 的自動(dòng)抖動(dòng)容限測(cè)試和快速總體抖動(dòng)測(cè)量，可以更快地執(zhí)行測(cè)試。J-BERT N4903B 是一項(xiàng)長(zhǎng)期投資，它可以根據(jù)當(dāng)前的測(cè)試和預(yù)算要求進(jìn)行配置，還可以從 N4903A 進(jìn)行升級(jí)，并在以后測(cè)試需求變化時(shí)對(duì)所有的選件和全速器件進(jìn)行改型。
