该波形发生器以单片机(MCS8031)为中心控制单元，由键盘输入模块、数码管显示模块、D/A波形发生模块dac0832、幅值调整模块组成。采用DDFS技术，先将要求的波形数据存储于EEPROM中，这样可以保证掉电以后波形数据不丢失。-The waveform generator to single-chip microcomputer (MCS8031) as the central control unit, by the keyboard input module, digital tube display module, D/A waveform occurred in module, the amplitude adjustment module. DDFS technology used, first the requirements of waveform data stored in EEPROM, so that after power-down waveform to ensure that data is not lost.
