基于FPGA的便携式DSO硬件电路的设计与实现

Design and Implement of Portable DSO Hardware Circuits Based on FDGA

提出了一种基于SOPC技术的便携式数字示波器的实现方案,设计以FPGA为系统的运算及控制核心,以高速ADC器件为信号采集模块,TFT彩屏液晶为显示器件的便携数字存储示波器。系统可实现信号波形显示、频率测量、峰峰值测量、均方根值测量及FFT功能。实际测试结果表明,系统工作稳定,显示效果良好。

A portable digital oscilloscope implementation scheme based on the SOPC technology, whichtakes FPGA as its core collection module and the core of control, ADC device as its collection module andTFT as its display device to meet the actual demand. System can realize the signal waveform display, frequency measurement, peak-to-peak value measurement, Root mean square value measurement and FFF.Actual test results show that the system works stable, display effect is fine.
