Virtual Arbitrary Waveform Generator Based on DDS Technology

Jian Cui

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.
