To meet the testers' need of capturing and observing the incidental or abnormal signals mixed in the cycle signal,this paper presented an intelligent triggering method for digital storage oscilloscope.First it analyzed the traditional test method was.inefficient and limited measurements and other drawbacks,and then introduced the intelligent triggering of the design plan,work processes and technological advantages,the core of which is the programmable trigger templates which can be arbitrarily set and judged by hardware in real-time.Finally,the technology was applied to a type of digital storage oscilloscopes and the application of verification results was given.Tests show that the technology has a high efficiency to capturing occasional,abnormal event,is a useful complement for the function of oscilloscope waveform capture.
