基于普通示波器的频谱分析装置设计

Design of frequency spectrum analysis device on the ordinary oscillograph

设计了一种为普通示波器加装频谱分析功能的装置,该装置以DSP芯片TMS320F206为核心,对信号滤波后,经A/D,FFT运算后得到频谱数据,再经D/A转换为模拟信号,由示波器显示出信号的频谱结构,操作简单,易于实现.

A frequency spectrum analysis device for ordinary oscillograph is designed. After filtering input signal,this device with DSP chip TMS320F206 as core gets digital signals by A/D, FFT operation, and then changes it into analog signal by D/A, demonstrating the spectral structure of the signal by the oscillograph. With the application of this device, this device can he operated and realized casily.
