| Abstract: | Frequency sweep signal source plays indispensability role in transmitter and test device. Designing a kind of flexible frequency sweep device has important significance. The paper analyzes the structure of DDS. Using two DDS IP cores, frequency sweep device is designed. The device which could choose different frequency span, center frequency and sweep pattern, can almost meet frequency sweep source requirement. |
