Low voltage 24v thermostat soldering pen protects the faulty circuit board 低壓恒溫24v烙鐵有效保護(hù)維修線路板。
A united stimulation acquisition algorithm was designed for detecting the faulty circuits under automatic test equipment in order to decrease the test cost 設(shè)計(jì)了適合自動(dòng)測(cè)試系統(tǒng)進(jìn)行模擬電路參數(shù)故障檢測(cè)的聯(lián)合激勵(lì)方式提取算法以降低測(cè)試成本。
Three different d - fronts are defined in this paper , and the test generation is consisted of three parts : to excite the fault at first ; to maximize the iddt difference between fault - free circuit and faulty circuit at second ; and finally to minimize the effect of bypass 文中定義了三種不同的d前沿,并將測(cè)試生成分為三個(gè)部分: 1 、激活故障, 2 、使無(wú)故障電路和故障電路的瞬態(tài)電流差別最大化, 3 、減少旁路的影響。
Among the many testing methods of analog and mixed signal circuits booming up in recent years , the pseudorandom testing technique is easier to generate testing stimuli and the current - based testing method could magnify the response differences between fault - free circuits and faulty circuits 近年來(lái)提出的很多種模擬及混合信號(hào)電路測(cè)試方法中,偽隨機(jī)測(cè)試法易于產(chǎn)生測(cè)試激勵(lì),基于電流的測(cè)試法能使正常電路和故障電路的頻率響應(yīng)的差別增大。
