關(guān)于如何確定石英晶振中峰與峰之間的抖動,Cardinal晶振已確定精確測量晶體振蕩器的抖動，在OR處低于1皮秒，這是目前唯一的方法,可用于測量石英晶振相位噪聲并計算有效值抖動。請參閱我們的應(yīng)用說明“晶體振蕩器用于低抖動應(yīng)用“的完整解釋。測量晶體振蕩器的相位噪聲，我們使用雙源方法。這導(dǎo)致單個1Hz帶寬內(nèi)相位的邊帶測量在特定偏移頻率范圍內(nèi)。單邊帶相位噪聲結(jié)果為在指定的頻率帶上積分，通常為10Hz至1MHz或12kHz至20MHz，具體取決于應(yīng)用程序。SONET要求帶寬為12kHz至20MHz。此頻域集成相位噪聲（以dBc/Hz為單位）然后轉(zhuǎn)換為時間,RMS抖動（以皮秒為單位）。
在Cardinal晶振的非PLL振蕩器中，RMS抖動具有隨機高斯分布，因為沒有使用鎖相環(huán)路。這個結(jié)果在缺乏離散雜散和多模態(tài)的情況下非高斯分布。因此，很少或沒有由低噪聲供電時的確定性抖動電源。當抖動具有高斯時響應(yīng)，RMS抖動是標準差或一個西格瑪值。
基本組件中使用的石英晶體振蕩器具有非常高的Q值。加載的Q的振蕩器諧振器環(huán)路在10，000到超過100，000。當振蕩器級產(chǎn)生信號，頻率可以駐留在振蕩帶寬。但是，對于高Q諧振器實現(xiàn)窄振蕩帶寬、振蕩器可以制造出非常低的抖動。
基數(shù)抖動的高斯分布組件振蕩器，周期的平均值位于高斯曲線的中心。標準偏差（1西格瑪）定義為包含發(fā)生的總振蕩的68.26%。這窗口放置在均值的一側(cè)。1西格瑪（標準偏差）值是振蕩器輸出信號。作為標準的數(shù)量偏離均值增加，幾率振蕩器產(chǎn)生該周期偏差的信號大大減少。在14.069西格瑪時，概率為1：1012.光纖通道規(guī)格要求14西格瑪可靠性。
Cardinal晶振確定峰到峰（Pk到Pk）值取決于關(guān)于所需的可靠性。可靠性越高,Pk到Pk值越大，即使發(fā)生概率隨著更高的西格瑪值。在14西格瑪時，概率接近1：1012.這被認為是我們用來確定的標準RMS抖動值的Pk到Pk抖動。如果組件振蕩器具有2皮秒RMS抖動，Pk到Pk抖動為28皮秒。
