摘要
针对频谱分析仪价格昂贵、操作复杂,不适合实验室的一般教学与仿真等问题,根据虚似仪器的设计理论,介绍了一种基于USB2.0总线的虚似频谱分析仪的设计过程.该设计采用TI公司的THS1206A/D转换芯片实现信号的采集功能.USB2.0接口芯片采用Cypress公司Cy7c68013芯片,将采集的信号传送至PC机.最后在上位机实现数据的存储、FFT运算与图像绘制.设计的结果基本满足实验室的一般教学与仿真要求.
Introducing the process of a design of virtual spectrum analyzer based on the shortages of conventional spectrum analyzer, such as, exorbitant price, complex operations and inconformity for teaching and simulation in the labs, the design is using TI THS1206 to make data acquisition and Cypress cy7c68013 to transport the data to PC for the data storage, FFT operation and display. The results show that the design is rational for the teaching and simulation demands of the labs.
