With the progress of society signal measurement and analysis have more widely range of applications, but the spectrum analyzer was generally expensive to make it difficult for popularization and application. In this paper, a design methodology of low cost, stable reliable spectrum analyzer based on the idea of Software Defined Radio (SDR) is presented, which consists of three functional units. The STM32 is the core of spectrum analyzer and is the key base to signal acquisition and analysis of the system. This paper designs the detailed hardware circuit and the software and optimizes the display program to obtain a higher refresh rate. Through testing the design is stable and reliable, simple and practical, and suitable for use in scientific research and industry production.
