摘要
采用DDS (直接数字频率合成 )技术设计了任意波形发生器。系统时序和逻辑电路主要由一块CPLD芯片来完成 ,软件构建于LabWindows/CVI这一专用虚拟仪器软件开发平台之上 ,其特点是界面友好 ,操作方便 ,产生的波形失真度小 ,频带宽 。
The arbitrary waveform generator is developed based on DDS(direct digital synthesizer)technology. Its timing and logic function is fulfilled by CPLD. The software is based on a special Virtual Instrument Software Development Kit-LabWindows/CVI. So this generator has a friendly GUI and can operates expediently. The waveform produced is of low distortion, wide frequency range and high frequency resolving ability.
