Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include
most small appliances, test equipment, and
other devices that plug into a branch outlet
or socket. The 34401A may be used to make
measurements with the HI and LO inputs
connected to mains in such devices, or to
the branch outlet itself (up to 300 VAC).
However, the 34401A may not be used with
its HI and LO inputs connected to mains in
permanently installed electrical devices
such as the main circuit-breaker panel,
sub-panel disconnect boxes, or permanently
wired motors. Such devices and circuits are
subject to overvoltages that may exceed the
protection limits of the 34401A.
Note: Voltages above 300 VAC may be measured only in circuits that are isolated from
mains. However, transient overvoltages are
also present on circuits that are isolated
from mains. The Agilent 34401A are
designed to safely withstand occasional
transient overvoltages up to 2500 Vpk. Do
not use this equipment to measure circuits
where transient overvoltages could exceed
this level.

電子產品的設計一般先從功能框圖開始,然后細化到原理圖,還要經過很復雜和繁瑣的調試驗證過程,最終才能完成。為了驗證原理圖的正確性,都要焊接實驗板(樣板),或使用易于插件的“面包板”,每個節點都必須正確和可靠,連接或焊接過程都是細致而耗時的工作,在器件很多時幾乎是不可能完成的任務,而每次調整都要打樣,耗時長而成本高,在設計集成電路時更是如此,急需在制造之前驗證集成電路的功能。這種現實需要就迫使人們想用他辦法來解決。 根據電路理論,人們可以建立起節點方程和回路方程,通過解這些方程組成的方程組就可以得到結果,也就是說可以通過計算來獲得電路的工作情況。但包含電感、電容等器件的電路形成的是一組微分方程組,人工計算依然是累人的活,而計算機則可以大展身手,通過其強大的存儲、計算和圖形顯示能力就能輕松完成,很快得到結果。基于這種思想,人們開發出電路仿真軟件,通過快速的仿真,代替耗時且累人的反復調測,提高設計速度和效率,也節省了時間和成本。最早、最出色的仿真軟件就是SPICE。SPICE是Simulation Program with Integrated Circuits Emphasis的縮寫,由美國加利福尼亞大學伯克利(Berkeley)分校的電工和計算機科學系開發,骨干是Ron Rohrer和Larry Nagel,開始是使用FORTRAN語言設計的仿真軟件,用于快速可靠地驗證集成電路中的電路設計以及預測電路的性能。第一個版本SPICE1于1971年推出,通過圍繞晶體管建立電流和電壓變量來仿真電路的行為,稱為模擬仿真或電路級仿真,且只能模擬100個晶體管的電路。1975年SPICE2發布,開始正式實用化,1983年發布的SPICE2G.6在很長時間內都是工業標準,它包含超過15000條FORTRON語句,運行于多種中小型計算機上。1985年SPICE3推出,轉為用C語言開發,易于運行于UNIX工作站,還增加了圖形后處理工具和原理圖工具,提供了更多的器件模型和分析功能。在1988年SPICE被定為美國國家標準。Spice仿真器采用修改的節點分析法來建立電路方程組,提供非線性直流分析,非線性瞬態分析(實域分析)和線性小信號分析(頻域分析)等。其中瞬態分析是最費時的驗證方法,通常是利用數值積分法把非線性微分方程變成一組代數方程組,然后用高斯消去法來求解,因為這些線性方程僅僅在積分時刻點是有效的,而隨著仿真器進展到下一個積分步長,積分方法必須重復來得到新的線性方程組,如果信號變化得特別快,積分步長應該取得非常小以便積分方法能收斂到正確的解,因此瞬態分析需要大量的數學操作。隨著SPICE的發布,其他一些機構也加入研究行列,更有一些軟件供應商也看中這個商機,紛紛推出基于SPICE3的各種商業軟件,如XSPICE、PSPICE、ISSPICE、T-SPICE、HSPICE等等,功能更強,更方便使用,使SPICE成為電子電路仿真的主流軟件,一些軟件公司也是通過SPICE相關軟件得到發展,并逐漸成為現在的EDA軟件公司,成為知識創造財富的實例。因為SPICE仿真需要相關的元器件仿真模型庫,還催生了依靠提供器件模型為生的公司和個人,但中國人都樂于奉獻,沒錢當然不會買,這種公司在中國是無法存在的(http://www.aeng.com/spicemodeling.asp )。SPICE軟件也有一定局限性,有些電路無法仿真或仿真時因不能收斂而失敗,特別是用于數模混合電路及脈沖電路時尤其如此。就算通過仿真,最終還是要通過實際制作電路板調試和驗證,仿真只是使這個過程大大縮短,次數大大減少,也就降低了成本。軟件能提高效率和降低成本,所以就有相應的價值,但中國人的人工費低廉而有的是時間,干得好干得快才讓人討厭,軟件在中國也就不值錢了。
