| 摘 要： | 介绍了一种基于89C55单片机的三通道跟踪式智能任意波形发生器。给出了硬件电路的基本结构以及软件的编程方法。波形的产生电路是由单片机系统和三相查表电路组成，它们不断地从EEPROM中取出波形点阵的数据，通过DAC和LPF电路输出周期波形。信号波形的点阵数据可由单片机编程、实际波形的采集或PC机下载获得。该仪器能同时输出三相波形，其波形的频率、相位和幅值可程控，并且其波形、频率、相位可在LCD液晶显示器上实时显示。

| Abstract: | This paper introduces an intelligence arbitrary waveform generator of three-channel tracing,based on 89C55 chip-microprocessor.The structure for designing the hardware and software was studied.The circuit of making waveform was made up microprocessor system and three table look-up circuit,which getting waveform data from EEPROM continually and producing cyclic waveform by DAC and LPF.The waveform data of the instrument was got from MCU,data collector system or PC.The instrument gives three-channel waveform at one time.The waveform,frequency and voltage were controlled by MCU.The waveform,frequency and phase position was displayed on LCD real time. |
