摘要
针对测控领域中可控方波信号的特点,在LabVIEW平台上设计并开发了可控方波信号源,该信号源包含方波信号生成、输出端口扩展、端口联动控制、信号类型选择等4个模块,能够根据需要,分别设置信号频率、幅值、相位、方波占空比,生成相应的高精度方波信号,满足现代工程测量的需要。
According to the feature of that controllable square signals in the field of measurement and control, the controllable square signal source generator was designed and implemented with LabVIEW. The generator included controllable square wave signal source generator module, output port expansion module, port coordinated controlling module and signal type selection module, and could create the relevant high accuracy square signals by setting the signal frequency, amplitude, phase and duty ratio, to meet the need of modern engineering survey.
