| Abstract: | This paper adopt SCM STM32F407 and FPGA as the main control unit, with AD9958 to generate local oscillator signal, through Multiplier and measured signal mixing, coupled with filter, amplification and A/D conversion process. Finally achieve spectrum analysis of 80-100MHz band, and display spectrum on the FTF touch screen. The experiment show that the system control mode is flexible and practical, and has a good general and promotion prospects. |
