摘　　要：本文介绍了一种混合扫描显示系统。该系统利用普通电磁偏转 CRT 显示器经简单改装后做为监视装置。该系统配有相应的软件及硬件电路,需显示的曲线由并行输入接口以八位数字量输入,显示于随机扫描区;需显示的字符由另一并行输入接口输入,显示于光栅扫描区。This paper introduces a hybrid scanning display system.The system uses an ord nary electro-magnetic deflection CRT monitor simply refitted as monitoring unit. The waveform to be displayed is inputted through parallet input interface by 8 bit A/D conversion and displayed in the random scanning region.The characters to be displayed are inputted through anoth- er parallel input interface and displayed in the raster scanning region.
