硬件觸發：數據采集卡被動等待觸發信號，接收到信號後才進行數據采集；觸發信號可由某個儀器在一定狀態下發出。如有的自動測量係統中的高速數據卡就接收position controller發(fa)出(chu)的(de)觸(chu)發(fa)信(xin)號(hao)。而(er)有(you)的(de)則(ze)依(yi)靠(kao)矢(shi)量(liang)網(wang)絡(luo)分(fen)析(xi)儀(yi)接(jie)收(shou)外(wai)部(bu)觸(chu)發(fa)信(xin)號(hao)。之(zhi)所(suo)以(yi)能(neng)接(jie)收(shou)觸(chu)發(fa)信(xin)號(hao)，和(he)儀(yi)器(qi)的(de)工(gong)作(zuo)模(mo)式(shi)有(you)關(guan)。硬(ying)件(jian)觸(chu)發(fa)與(yu)數(shu)據(ju)采(cai)集(ji)卡(ka)有(you)關(guan)。
