摘　　要：详细介绍了一种基于MAX038,以STC89C52为主控部件的函数信号发生器的设计。通过键盘设置输出波形、波形的频率和步进值,使其输出规定的波形。波形频率在10 Hz～1 MHz范围内步进可调、幅度在0～5 V范围内步进可调,输出波形稳定,失真度很小。this article introduce a signal generator which is based on MAX038 controlled by STC89C52.Setting the signal＇s waveform,frequency,step-value by key-press,made it generate the sated waveform.Frequency can be adjust from 10Hz to 1MHz step by step,amplitude can be adjust from 0V to 5V step by step too.It can output steadily waveform and the distortion is very small.

关 键 词：函数发生器 MAX038 步进调节 程控
