Keysight N4877A 時脈資料還原裝置係為 50 Mb/s至 32 Gb/s 速率之操作環境所設計。其寬廣的資料速率範圍讓您不僅可針對目前的標準進行測試,更可測試未來的 100 GbE 與 FCx32 標準。 另有 16G 選項可供選購,以便用高達 16.5 Gb/s 的速率,測試 FCx16 與 USB 3.0、SATA、SAS、PCIe(包含 PCIe gen4)等電腦標準。
如過您無法獲得待測裝置(DUT)之時脈信號時,Keysight N4877A 可提供BERT或取樣示波器所需的時脈信號。如果您無法取得時脈時,Keysight N4877A 可經由資料串流還原時脈,或是當既有時脈內含過多固有抖動時,當作清理鎖相迴路(clean-up PLL),以進行精確的量測。
Keysight N4877A 時脈資料還原裝置與 1:2 解多工器之組合,是 Keysight N4876A 2:1 多工器的對應產品,可用於內含 Keysight J-BERT 與 ParBERT之接收器測試解決方案,以支援 12.5 Gb/s 與 28.4 Gb/s 之資料分析速率。
利用軟體控制的可置換式解多工器輸出、抖動容忍度測試模式以及特別為 Keysight J-BERT N4903B 設計的連接線套件,來簡化接收器測試。
量測無震盪器裝置之真實效能
低固有抖動搭配可調整的迴路頻寬、可選的峰值和高靈敏度,使其可進行準確的發射器量測。
Keysight N4877A 輔助時脈輸出提供小於 100 fs rms 的超低固有抖動,使其成為具備精確時基之取樣示波器的理想配備。
簡單控制所有的設定
您可透過後面板的 USB 連線以及在 Windows® 電腦上執行的獨立使用者介面,控制 Keysight N4877A 的設定值。
