中文摘要：
针对测试者捕捉和观察混杂在周期信号中的偶发、异常信号的需求,提出了一种数字存储示波器的智能触发方法。首先分析了传统测试方法效率低、测量方法受限等弊端,然后介绍了智能触发技术的总体设计方案、工作流程和技术优势,其核心是通过硬件实时判别能任意设置的可编程触发模板,最后给出了将该技术实现于某型号数字存储示波器的具体实施方法以及应用验证结果。测试表明,该技术具有较高的偶发、异常事件捕获效率,是对示波器波形捕获功能的有益补充。
英文摘要：
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.
