本文叙述了应用数字瞬态测试技术研制智能化高速瞬态波形记录仪系统.本系统可以20 MHz 采样速率双通道对模拟信号进行数字采集,存储,显示和分析处理;分辨率为8个比特;每通道内存量为8k×8比特.本系统设计中采用的 A/D 是模拟器件公司的 MATV—0820型,采用一次并行比较,其最高工作速率为20MHz.达到了本系统高速采集数据的目的.本系统的另一主要特点就是采用数字比较触发方式,可准确地用数字规定触发电平,具
This paper describes the application of digital transient test technology to develop intelligent high-speed transient waveform recorder system.The system can 20 channel sampling rate of 20 MHz analog signal digital acquisition, storage, display and analysis processing; resolution of 8 bits; Each channel of memory is 8k × 8 bits. A / D used in the system design is the MATV-0820 analog device company, using a parallel comparison, the maximum operating speed of 20MHz. To achieve the purpose of this system to collect data at high speed Another major feature of this system is the use of digital comparison trigger mode, which can be accurately used to trigger the level of digital provisions, with
