摘要
论述以两片单片机和MAX038精密高频波形产生器为核心,辅以必要的外围电路,组成任意波形信号发生器。输出信号频率稳定,范围可达10Hz^1MHz,输出信号频率可分段调节,并且输出信号频率值和电压值可通过键盘进行设置,可实时显示输出信号的幅度、频率和频率步进值。采用128×64 LCD液晶提示功能显示,清晰稳定。
The random wave-form generator is elaborated in this article, which is composed of two MCU chips, the precise high frequency profile producer--MAX038, and the necessity periphery electric circuit. The output signal frequency is stable. The scope may reach 10Hz - 1MHz. The output signal frequency may be adjusted partitionly. And the output signal frequency value and the voltage value may be set through the keyboard. But the output signal scope, the frequency and the step value of frequency can be displayed in real time. 128×64 LCD liquid crystal prompt function is used to display clearly and stably.
