【Abstract】 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.更多还原
