從液晶儀表盤PCB圖不難看出與傳統(tǒng)儀表相比，全液晶儀表多了與顯示相關(guān)的部件，比如：顯示屏、GPU處理器、屏正負(fù)壓、屏背光等。改用液晶屏幕后不僅增加了產(chǎn)品軟硬件設(shè)計(jì)的難度，產(chǎn)品的EMC設(shè)計(jì)也成為產(chǎn)品設(shè)計(jì)的難點(diǎn)。由上圖R/G/B液晶屏的架構(gòu)可知，其主要包括時(shí)鐘電路、數(shù)據(jù)電路、供電電路。在高速數(shù)字系統(tǒng)中，固定頻率的時(shí)鐘是主要的電磁干擾源之一。隨著數(shù)據(jù)傳輸速率的提升，時(shí)鐘頻率越來越高，信號(hào)的邊沿率（即上升時(shí)間和下降時(shí)間）也隨之提高。
我司獨(dú)具有自營工業(yè)自動(dòng)化產(chǎn)品及技術(shù)進(jìn)出口權(quán)，公司與多家國外代理商建立了長期穩(wěn)定的合作關(guān)系。公司實(shí)力雄厚，重信用、守合同、保證產(chǎn)品質(zhì)量，以多品種經(jīng)營特色和薄利多銷的原則，贏得了廣大客戶的信任。
您的認(rèn)識(shí)是我們的希望，您的信任是我們的期待，產(chǎn)品與項(xiàng)目是我們的橋梁，服務(wù)與溝通是我們的責(zé)任，專業(yè)的服務(wù)，充足的庫存、期待您的來電咨詢！

與示波器傳統(tǒng)的FFT測試頻譜方法相比，SpectrumView具有獨(dú)到的優(yōu)勢，那么性能優(yōu)異的SpectrumView主要用于哪些場景呢？這是本文將重點(diǎn)介紹的內(nèi)容。本文將以泰克新一代示波器MSO64為實(shí)例來講解時(shí)頻域信號(hào)分析技術(shù)。MSO64采用全新TEK049平臺(tái)，不僅實(shí)現(xiàn)了4通道同時(shí)打開時(shí)25GS/s的高采樣率，而且實(shí)現(xiàn)了12-bit高垂直分辨率。同時(shí)，由于采用了新型低噪聲前端放大ASIC—TEK061，大大降低了噪聲水平，在1mv/div時(shí)，實(shí)測的本底噪聲RSM值只有58uV，遠(yuǎn)遠(yuǎn)低于市場同類示波器。

其更常用的說法為折合到輸入端噪聲。折合到輸入端噪聲通常用將直流輸入施加到轉(zhuǎn)換器時(shí)的若干輸出樣本的直方圖來表征。大多數(shù)高速或高分辨率ADC的輸出為一系列以直流輸入標(biāo)稱值為中心的代碼。為了測量其值，ADC的輸入端接地或連接到一個(gè)深度去耦的電壓源，然后采集大量輸出樣本并將其表示為直方圖（有時(shí)也稱為“接地輸入”直方圖）-見。由于噪聲大致呈高斯分布，因此可以計(jì)算直方圖的標(biāo)準(zhǔn)差σ，它對(duì)應(yīng)于有效輸入均方根噪聲，表示為LSBrms。
