| 摘 要： | 以ADI公司的高性能DDS芯片AD9910为核心,以TI公司的低功耗单片机MSP430为控制器,设计了一种信号发生器。目前的信号发生器产生信号单一,频率较低,不能满足某些需要多模式高频信号场合的要求,为了解决这个问题,采用单片机直接控制DDS芯片的方法,设计了一种能产生高频多模式信号的信号发生器,能够输出高达400 MHz的信号,频率分辨力可达0.23 Hz,还能够进行多级的相移键控和频移键控调制。

| Abstract: | This paper designed a kind of signal generator, with the high performance DDS chips AD9910 made of the ADI Company as the core and the low power consumption MCU MSP430made of the TI Company as controller. The current signal generator signal a single low frequency, can not meet certain requirements which require multi-mode high-frequency signal. To solve this problem, a signal generator is designed to generate high-frequency multi-mode signal, using of the MCU directly control the DDS chip. This generator can output 400MHz signal, and frequency resolution is up to 0.23Hz, it still can make multi-step Phase Shift Keying and Frequency Shift Keying modulation. |
