眾所周知，CANFD是基于CAN2.0的升級(jí)版協(xié)議，為了滿足汽車電子日益增長的高帶寬和高傳輸速率的要求，CANFD主要升級(jí)了以下幾個(gè)方面：更高的傳輸波特率可變數(shù)據(jù)段波特率結(jié)構(gòu)CANFD速率包含兩個(gè)段的速率，其中仲裁段和ACK段沿用CAN2.0的規(guī)范，速率為1Mbit/s，中間的數(shù)據(jù)段是可以加速的，標(biāo)稱可以達(dá)到5Mbit/s，甚至更高。更的數(shù)據(jù)段對(duì)于汽車電子來說，對(duì)車輛動(dòng)力系統(tǒng)、底盤以及主被動(dòng)系統(tǒng)來說，加長的數(shù)據(jù)段避免了數(shù)據(jù)非必要的拆分，大大提升了CAN幀的傳輸效率。

低功耗與環(huán)境適應(yīng)性：低功耗是便攜式產(chǎn)品研究的重點(diǎn)，功耗決定了產(chǎn)品的使用時(shí)間及可用性，同時(shí)對(duì)溫度、濕度、防水和偶然跌落等的環(huán)境適應(yīng)能力也是便攜式產(chǎn)品競爭的主要指標(biāo)。高精度：隨著集成芯片制造技術(shù)、數(shù)字采樣技術(shù)和微處理器速度的提高，便攜式儀表的高準(zhǔn)確度、高分辨率測(cè)量的研究已成為主要方向。過載自動(dòng)保護(hù)、故障自診、記錄與報(bào)警。芯片：數(shù)字萬用表的發(fā)展主要依賴于集成芯片技術(shù)的進(jìn)步，便攜式產(chǎn)品的核心技術(shù)就是集成芯片，多功能、低功耗、高可靠、高精度、低成本、小體積、嵌入式微處理器及接口將成為芯片的主要發(fā)展方向。

如果只在豎直(Y軸)偏轉(zhuǎn)板上加一交變的正弦電壓Uy=U0sinωt，則電子束的亮點(diǎn)將隨電壓的變化在豎直方向來回運(yùn)動(dòng)。由于Ux=0，所以光點(diǎn)在X軸方向無位移，在熒光屏上將顯示一條豎直亮線。如果只在水平(X軸)偏轉(zhuǎn)板上加上一個(gè)與時(shí)間成正比的鋸齒波掃描電壓Ux=KT(它可由示波器內(nèi)的掃描發(fā)生器產(chǎn)生的)，電子束將在水平方向作周期性地從一邊勻速移動(dòng)到另一邊，如果鋸齒波的周期較長，在熒光屏上可以看到電子束的移動(dòng)過程，如果鋸齒波的周期足夠短，熒光屏上將只顯示一條水平亮線。
