| Abstract: | The basic principle of AD9850 and a high signal source system based on AD9850 are decribled. For more wide frequency , DDS + PLL is used in this system. The high frequency signal source can realize FM modulation and it's amplitude and frequency can be regulated digitally. The frequency range of signal source is between 10kHz and 100MHz. |
