摘要
本设计是由MSP430F5438A作为主控芯片,控制集成芯片AD9834 DDS信号发生器产生两路本振扫频信号,一路本振信号通过MC13136进行信号混频后检测载波信号频率;另一路通过AD8343混频器放大检波采样,确定当前载波信号的功率值。最终由串口触摸显示屏选择性的显示当前信号频率和功率值。设计实现了对15.00~30.00 MHz高带宽的高频载波信号信息的采集、处理、显示等功能。
In this design,MSP430 F5438 A is used as the main control chip to control the integrated chip AD9834 DDS signal generator to generate two local oscillator sweep signals,and one local oscillator signal is used to detect the carrier signal frequency after signal mixing through MC13136.The power value of the current carrier signal is determined by amplifying detection sampling through AD8343 mixer.Finally,the serial touch screen selectively displays the current signal frequency and power value.The acquisition,processing and display of high frequency carrier signal information with high bandwidth of15.00~ 30.00 MHz are realized.
