摘要
利用图形化的编程环境LabVIEW6.1及VISA标准,编程实现了PC与自制信号发生器的串行通信.通过操作完全仿真的虚拟面板,PC发出各种指令,控制信号发生器产生不同频率和信噪比的波形,并实时获取和显示其运行参数,从而完成信号发生器单机操作的所有功能.
To control home- built signal generator through the serial port, a virtual instrument (Ⅵ) with emulational panel was designed using LabVIEW 6.1 and VISA standard. When the user clicks the buttons of the virtual panel, PC sends out various orders to the signal generator for kinds of waveforms with variable frequency and signal - to - noise ratio, obtains and displays the instrumental parameters instantaneously.
