| Abstract: |
| Based on direct digital synthesizer(DDS) technology and digital orthogonal upconverter AD9857,an arbitrary waveform synthesizer is realized,which can generate arbitrary waveform in the frequency domain of 6~60MHz.Simulation and experiment results prove its feasibility and practicability. |
| Key words: direct digital synthesizer(DDS),arbitrary waveform synthesizer,digital orthogonal upconverter |
