一、概述随着电子计算机和外围设备的发展以及数字技术应用于各个领域,使电子测量仪器出现了一种崭新的门类-数据域仪器.而最典型、用途最广泛的便是逻辑分析仪,也称逻辑示波器.自1973年第一台逻辑分析仪问世以来,在短短几年中已经取得了飞速发展,从一般逻辑状态测试已发展到了可对各类硬件、软件的故障或它们故障的混合进行快速的测试与分析,如对微处理器的快速测试等. I. Overview With the development of electronic computers and peripherals and the application of digital technologies in various fields, electronic measurement instruments have emerged as a brand new category - data domain instruments. The most typical and most widely used are logic analyzers, Also known as Logic Oscilloscope. Since the first logic analyzer was introduced in 1973, it has achieved rapid development in just a few years. From the general logic state test, it has been developed that it can be used for all kinds of hardware and software failures or their failures Mix for rapid testing and analysis, such as rapid testing of microprocessors.
