磁盤驅(qū)動(dòng)分析的解決方案

性能

力科磁盤驅(qū)動(dòng)分析儀(DDA)內(nèi)置的工具可以協(xié)助數(shù)據(jù)存儲(chǔ)工程師，加快新產(chǎn)品推向市場(chǎng)的速度，加快對(duì)現(xiàn)存的驅(qū)動(dòng)器的理解和失效分析。力科持續(xù)著DDA 7Zi-A系列的傳統(tǒng)，為其配備強(qiáng)大的磁盤驅(qū)動(dòng)分析工具箱。快速完整地捕獲、觀察并分析高速?gòu)?fù)雜的驅(qū)動(dòng)器信號(hào)波形。

數(shù)據(jù)存儲(chǔ)應(yīng)用對(duì)存儲(chǔ)器非常敏感，例如捕獲多個(gè)扇區(qū)或一個(gè)完整軌道的數(shù)據(jù)，對(duì)解決設(shè)計(jì)的故障或?qū)橘|(zhì)定性具有很重要的意義。

X-Stream II架構(gòu)可以快速精確地測(cè)量分析磁盤驅(qū)動(dòng)器信號(hào)。使用選件L可以將存儲(chǔ)器擴(kuò)展到128 Mpts/Ch(2個(gè)通道256 Mpts/Ch)。DDA 760Zi和DDA 735Zi均可方便地選擇50Ω或1MΩ輸入。2個(gè)通道上標(biāo)配20 Mpts波形存儲(chǔ)器和 40 GS/s 采樣速率，意味著多驅(qū)動(dòng)器扇區(qū)可被同時(shí)采樣。

長(zhǎng)存儲(chǔ)和查找問(wèn)題的靈活性

獲取一個(gè)高達(dá)6GHz的頭信號(hào)，然后使用前面板的快速縮放按鈕對(duì)其進(jìn)行縮放。DDA會(huì)自動(dòng)復(fù)制并擴(kuò)展該驅(qū)動(dòng)器信號(hào)。簡(jiǎn)單地水平和垂直滾動(dòng)，檢查任意扇區(qū)。多個(gè)縮放可以使您從8個(gè)各自區(qū)域觀察到該頭信號(hào)；每個(gè)縮放使用不同的顏色。磁盤驅(qū)動(dòng)參數(shù)可以使您對(duì)脈寬的變化或某個(gè)區(qū)域內(nèi)的信噪比進(jìn)行定性分析。失效分析工程師可以存儲(chǔ)并回調(diào)重要波形和面板設(shè)置來(lái)對(duì)比問(wèn)題驅(qū)動(dòng)器和正常驅(qū)動(dòng)器。模數(shù)轉(zhuǎn)換器在高達(dá)40 GS/s的速度運(yùn)行，以保證可以對(duì)今天的高速讀通道的測(cè)量具有足夠的敏感度。使用每臺(tái)DDA，您都可以運(yùn)行您的自定義腳本，配合與您的通道和介質(zhì)匹配的濾波器來(lái)觀察捕獲的信號(hào)。用戶自定義腳本可以通過(guò)MATLAB、Visual Basic、Excel或其他格式來(lái)創(chuàng)建。

特殊觸發(fā)和序列性能

DDA的磁盤觸發(fā)可以使您對(duì)信號(hào)設(shè)置一系列的事件并開(kāi)啟觸發(fā)。例如，驗(yàn)證索引信號(hào)上的信號(hào)并捕獲磁道上所有扇區(qū)的信息。隨著DDA上存儲(chǔ)器的增加，在高達(dá)50微秒/采樣的事件分辨率下，更多的扇區(qū)可被捕獲。DDA 7Zi-A分析儀可以收集最多15,000個(gè)扇區(qū)的數(shù)據(jù)。另一個(gè)附加功能，流序列，使用DDA的X-Stream II和快速硬件架構(gòu)，可以將最多300,000片數(shù)據(jù)存流入存儲(chǔ)器中；并且采用高速觸發(fā)頻率。

自然圖形界面

按一下DDA菜單，可以使您直接跳至磁盤驅(qū)動(dòng)分析儀功能。前置面板上類似的控制，外加一個(gè)自然的上下文相關(guān)圖形用戶界面，可以快速響應(yīng)您的命令。該功能正是您想要的。

DDA 7Zi-A提供了一鍵調(diào)用全部工具，來(lái)進(jìn)行準(zhǔn)確的調(diào)試和分析磁盤驅(qū)動(dòng)的工作。
