摘　　要：基于虚拟仪器技术的数字示波器与传统示波器相比,在信号采集上显示了巨大优势,但对于采集信号的触发显示功能就需要完全通过软件编程的方法来解决。运用虚拟仪器编程软件LabVIEW,通过对三种最基本、最常见的信号触发方式的编程实现,研究在虚拟仪器技术下实现各种触发方式的方法及各方法的特点与适用领域。Compared with the traditional oscillograph, the digital oscillograph based virtual instrument technology shows many advantages in signal acquisition.But the trigger display function of the digital oscillograph to acquisition signal can only achieved through software programming,The authors completed programming on three basic and familiar signal trigger modes by LabVIEW programming software of virtual instrument, researched the methods of realizing kinds of trigger modes in virtual instrument technology, and analyzed the characteristic and applicability of these methods.
