【摘要】 针对频谱分析仪价格昂贵而无法普及的问题,采用TI的TMS320VC5402芯片设计一个以普通双踪示波器作为输出设备的简易频谱分析仪.为此,首先阐述了利用高性能的DSP芯片设计频谱仪的优点.并对整个系统的功能模块逐一进行了介绍,给出了部分电路图、硬件方框图及软件流程图.更多还原

【Abstract】 Considering that the spectrum analyzer is costly, and its popularization is limited, this article presents a simple spectrum analyzer which is designed by DSP chip and based on common double tracking oscilloscope. It expound the advantage of spectrum analyzer designed by DSP chip and gives a detailed statement of every function module. The hardware block diagram, part of circuit diagram and software system of a DSP spectrum analyzer are given.更多还原
