利用示波器对电路进行波形测试、分析是科研、生产中对电路参数进行分析调整的常用手段,目前在科研部门、工厂企业中广泛使用通用示波器作为波形检测工具,而某些场合(如电路的暂态特性)常常需要将瞬态、单次波形记录下来,现在厂家生产的记忆示波器价格极为昂贵、记忆效果也不好(利用一种特殊示波管),且没有存贮功能。国内外对数字示波器的研究在不断取得进展。随着微电脑的广泛应用,在普通示波器上进行波形的记忆,记录和输出已由可能变为现实,本文介绍利用MCS 48TM系列单片机8039组成模拟信号存贮、
The use of oscilloscopes for waveform testing circuit, analysis is scientific research, production of circuit parameters analysis and adjustment of commonly used means, now widely used in scientific research departments, factories and enterprises as a general oscilloscope waveform detection tools, and some occasions (such as the circuit temporarily State characteristics) often need to transients, a single waveform recorded, and now manufacturers of memory oscilloscopes are extremely expensive, memory is not good (using a special oscilloscope), and no storage capabilities. Research on digital oscilloscope at home and abroad is constantly making progress. With the extensive use of microcomputer, waveform memory, recording and output on a common oscilloscope has become a reality, this article describes the use of MCS 48TM Series 8039 analog signal storage,
