摘要
设计了一种实时频谱分析仪,该方案结合了SOPC可编程片上系统和虚拟仪器LabVIEW。采用NiosⅡ软核作为CPU,以FPGA、A/D芯片以及外围电路组成信号采集控制系统,利用通用异步接收/发送装置UART实现了与Lab-VIEW串行通信,实现了频谱分析仪的功能。仿真结果表明,该频谱分析仪具有实际应用价值。
A real-time spectrum analyzer was designed which combined the system on programmable chip and virtual instrument LabVIEW.In the system,Nios Ⅱ soft-core was used as CPU,and FPGA,AD-chip and the external circuit were used to constitute the system of signal acquisition and control.UART was adopted to realize serial communication with the LabVIEW,achieving the functions of spectrum analyzer.The simulation results showed that the spectrum analyzer has the value of practical application.
