摘要
针对频率变换器与同步器的测试过程繁杂这一问题 ,提出了以 AD985 0频率合成器为基础的逐赫兹可调的高精度信号发生器。此信号发生器以单片机为控制核心 ,用液晶模块显示频率 ,可发生正弦波与方波。在得到需要的信号后 ,讨论分析了稳定频率与改善方波波形的方法。
Hz adjustable function generator based on AD9850 is proposed for testing frequency transformer and synchronizer.The function generator is controlled by microcontroller.The frequency is displayed by LCD module. It can generate square wave and sine wave.Futhermore,some methods of stabilizing frequency and improving square wave are discussed,and the reasons of why are analyzed.
