Abstract

In this paper, we design a basic spectrum analyzer which can analyze the signal with the bandwidth in 10 MHz~100MHz and the minimum resolution in 100 KHz. We utilize the AD9854 DDS (Direct Digital Synthesizer), STM32F407, AD831, AD835 and the TFT LCD to design and implement a system that has menu-driven function selection mode and better man-machine interface. This system and actual test results showed that this spectrum analyzer can achieve the design goal. It reduces the cost and is portable with low power consumption.
