Design of Virtual Spectrum Analyzer Based on USB2.0

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.
