基于CV1任意波形发生器的整体设计 Integrated Design of Arbitrary Waveform Generator Based on CV

摘要:利用LabWindows/ CVI虚拟测控软件具有的超强实时数据采集和处理能力以及丰富的图形用户界面设计功能，开发了一个任意波形发生器编辑软件系统。介绍了一种用AVR系列单片机ATmega8来控制“'GA实现的DDS电路，并用SRAM取代ROM中的任意一种波形信号发生器硬件的设计。用这种方法设计的波形发生器结构简单、造价成本低，且信号源输出信号的分辨率高。

Abstract;By adoptingth esu periorpo werfulca pabilityfo rre al-timed ataa cquisitiona ndd atap rocessing,as w ela sth eri chG UIde signfu nctions provided IAbWindows/CVI virtual measurement and control software, an editing software system of arbitrary waveform generator is developed.The hardware design method of an arbitrary waveform generator is introduced, which, the DDS circuit is implemented controling FPGA with ATme single chip computer of AVR series, and replacing ROM with SRAM. The structure of the generator designed with this method is simple and low cost, in addition, the resolution of the output signal from the source is very high.
