在當今的高速數位設計中，您需要深入洞察抖動的成因。 相位雜訊是衡量信號產生器品質的最重要因素之一，也是影響航太與國防，以及通訊產業之關鍵應用效能的一大要素。
Keysight Infiniium 9000、S 系列、EXR 系列、MXR 系列示波器，可協助您執行抖動、垂直和相位雜訊分析。
藉由找出抖動與即時信號的時間關聯性，您可有效追蹤導致抖動的問題根源。 額外的相符性測試檢視畫面和量測設定精靈，可簡化並自動執行 RJ/DJ 分離過程，並依照產業標準進行測試。
此軟體可自動偵測示波器輸入端的嵌入時脈頻率及重複資料碼型，並在每次轉換碼型時，計算會影響總抖動（TJ）機率密度函數（PDF）的資料相依抖動（DDJ）位準。 此外，它具有頻譜和尾部擬合抖動分離演算法。 由於每個波形都是不同的，多個抖動分離解決方案可針對每個單獨的波形，提供更好的答案。 此軟體使用最新的尾部擬合演算法，可正確識別並量測無週期有界不相關抖動，尤其在波形受到串擾影響的情況下，這種演算法更為實用。
相位雜訊分析功能可量測一個時脈源內的相位雜訊。 量測結果以對數頻率座標圖呈現，其中振幅單位以 dBc/Hz 為單位列出（分貝對應到正規化至 1 Hz 頻寬的載波功率）。
