| Notes | GUO Rui-nan, LI Ye, WANG Yi-tao （Instrumentation and Electrical Engineering, Jilin University, Changchun 130026, China） field programmable gate array（FPGA）; frequency-characteristic measuring-testing instrument; virtual instrument; LabVIEW 31-1707/T Aiming to enhance the ability of data processing and take full advantage of computer resources,a virtual frequency-characteristic measuring-testing instrument is designed based on field programmable gate array（ FPGA） and under development environment of Lab VIEW. 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 |
