Abstract

Abnormal signal detection is a hot research in electronic test field. The digital storage oscilloscope detects abnormal signals by signal acquisition, abnormal signal identification, storage and display. Though the existing oscilloscope signal acquisition ability is technically improved by increasing the sampling rate, the waveform capture rate and other indicators, the identification, storage and display of abnormal signal show some deficiencies, which results in low abnormal signal detection efficiency and less application of detection function. The purpose of this paper is to improve the digital storage oscilloscope abnormal signal detection ability totally, design the abnormal signal detection system based on FPGA, study the method to improve the abnormal signal identification, storage and display, realize real-time, accurate identification and storage of abnormal signal in long period of time without manual monitoring, realize accurate offline positioning for abnormal signal in multiple display modes, and greatly improve the abnormal signal detection efficiency and practicability of the oscilloscope.

提高数字存储示波器异常信号检测能力的研究

异常信号检测是电子测试领域的一个研究热点。数字存储示波器通过信号采集、异常信号识别、存储和显示等步骤对异常信号进行检测。虽然现有示波器通过提高采样率、波形捕获率等指标从技术上提高了信号采集能力，但在异常信号的识别、存储和显示方面存在一定的不足，导致异常信号检测效率低，检测功能应用较少。为了全面提高数字存储示波器的异常信号检测能力，设计了基于FPGA的异常信号检测系统，研究了提高异常信号识别、存储和显示的方法，实现了长时间不需要人工监控的异常信号的实时、准确识别和存储，实现了多种显示方式下异常信号的准确离线定位。并大大提高了示波器异常信号检测效率和实用性。
