摘要
针对传统频谱分析仪器价格昂贵、维护成本高、操作复杂等问题,根据虚似仪器的设计理论,介绍了一种基于USB2.0总线的多功能虚拟频谱分析仪的设计过程,该设计采用ADI公司的AD9288BST-40芯片实现信号的采集功能,主控卡的FPGA芯片将采集的信号传送至上位机,然后在上位机实现多功能频谱分析仪的功能开发。最后通过功能测试结果验证了设计的可行性和准确性。
In view of the traditional spectrum analysis instrument is expensive,high maintenance cost,complex operation and so on,according to the theory of virtual instrument design,this paper introduces a design process of a kind of multifunctional virtual spectrum analyzer based on USB2.0.The design adopts the ADI company AD9288BST-40 chip to realize the function of signal collection.The FPGA chips of main control card will transmit the signal collected to the upper machine,and then realize the function of the multi-function frequency spectrum analyzer in the upper machine.Finally,functional test results verify the feasibility and accuracy of this design.
