　　凡(fan)是產(chan)生(sheng)測(ce)試信(xin)(xin)號(hao)的儀器(qi)，統稱為信(xin)(xin)號(hao)源，也稱為信(xin)(xin)號(hao)發生(sheng)器(qi)，它用于產(chan)生(sheng)被測(ce)電路所需特定參數的電測(ce)試信(xin)(xin)號(hao)。信(xin)號(hao)(hao)源是根(gen)據用戶對其(qi)波形的命令來產生信(xin)號(hao)(hao)的電(dian)(dian)(dian)子(zi)儀器。信(xin)號(hao)(hao)源主要(yao)給被(bei)測(ce)(ce)電(dian)(dian)(dian)路提供所需(xu)要(yao)的已知信(xin)號(hao)(hao)（各種波形），然后用其(qi)它儀表測(ce)(ce)量感興趣的參數。可見(jian)信(xin)號(hao)(hao)源在電(dian)(dian)(dian)子(zi)實(shi)驗和測(ce)(ce)試處理中，并不測(ce)(ce)量任(ren)何參數，而是根(gen)據使用者(zhe)的要(yao)求(qiu)，仿真(zhen)各種測(ce)(ce)試信(xin)號(hao)(hao)，提供給被(bei)測(ce)(ce)電(dian)(dian)(dian)路，以達(da)到(dao)測(ce)(ce)試的需(xu)要(yao)。

　　信號(hao)源(yuan)的分類和作用:信(xin)(xin)(xin)號源(yuan)有很多種(zhong)分類方(fang)法，其中(zhong)一種(zhong)方(fang)法可分為混(hun)和信(xin)(xin)(xin)號源(yuan)和邏輯(ji)(ji)信(xin)(xin)(xin)號源(yuan)兩(liang)種(zhong)。其中(zhong)混(hun)和信(xin)(xin)(xin)號源(yuan)主要輸(shu)(shu)(shu)出模擬波(bo)(bo)(bo)形(xing)(xing)(xing)；邏輯(ji)(ji)信(xin)(xin)(xin)號源(yuan)輸(shu)(shu)(shu)出數(shu)(shu)字碼(ma)(ma)(ma)(ma)形(xing)(xing)(xing)。混(hun)和信(xin)(xin)(xin)號源(yuan)又(you)可分為函(han)數(shu)(shu)信(xin)(xin)(xin)號發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)和任意波(bo)(bo)(bo)形(xing)(xing)(xing)/函(han)數(shu)(shu)發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)，其中(zhong)函(han)數(shu)(shu)信(xin)(xin)(xin)號發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)輸(shu)(shu)(shu)出標準波(bo)(bo)(bo)形(xing)(xing)(xing)，如正弦波(bo)(bo)(bo)、方(fang)波(bo)(bo)(bo)等(deng)，任意波(bo)(bo)(bo)/函(han)數(shu)(shu)發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)輸(shu)(shu)(shu)出用戶自定義(yi)的任意波(bo)(bo)(bo)形(xing)(xing)(xing)；邏輯(ji)(ji)信(xin)(xin)(xin)號發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)又(you)可分為脈沖信(xin)(xin)(xin)號發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)和碼(ma)(ma)(ma)(ma)型(xing)發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)，其中(zhong)脈沖信(xin)(xin)(xin)號發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)驅動較小個數(shu)(shu)的的方(fang)波(bo)(bo)(bo)或脈沖波(bo)(bo)(bo)輸(shu)(shu)(shu)出，碼(ma)(ma)(ma)(ma)型(xing)發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)生(sheng)(sheng)成(cheng)許多通道的數(shu)(shu)字碼(ma)(ma)(ma)(ma)型(xing)。如泰(tai)克生(sheng)(sheng)產的AFG3000系列就包括(kuo)函(han)數(shu)(shu)信(xin)(xin)(xin)號發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)、任意波(bo)(bo)(bo)形(xing)(xing)(xing)/函(han)數(shu)(shu)信(xin)(xin)(xin)號發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)、脈沖信(xin)(xin)(xin)號發(fa)(fa)(fa)生(sheng)(sheng)器(qi)(qi)(qi)(qi)的功能。
