Following the idea of modularity,the hardware circuit is constructed with a microcontroller as control unit,and a USB chip is used as the communication unit,in which FPGA realizes functions such as data storage and timing control,and improves the circuit＇s integration. Adopting the thought of dataflow,an interactive interface is developed in the graphical programming software of Lab VIEW,it contains functions of operating the instrument to generate swept-frequency signal,displaying frequency-characteristic c |
