- 摘要:
- 为了提高信号测量频率范围及实现小信号频谱的测量,采用超外差式原理,结合DDS与AGC设计了一款简易的频谱分析仪,该频谱分析仪可以测量频率范围为1～30 MHz、幅度为0.02～2 V信号的频谱.经实测表明,该频谱分析仪具有测量精度高、测量带宽大、成本低和便捷等优点,具有良好的实用价值.
- Abstract:
- In order to improve the measurement frequency range of the signal and measure the spectrum of small signal, a simple spectrum analyzer is designed based on DDS and AGC with the super heterodyne principle. The spectrum analyzer can measure the spectrum of signal with the frequency range from 1 MHz to 30 MHz, and can measure the spectrum of signal with amplitude from 20 mV to 2 V. The results of test show that the spectrum analyzer has the advantages of high measurement precision, wide measurement bandwidth, low cost and convenient, so it has good practical value.
