With the development of wireless communication technology, wireless modulation signal analyzer has an important role in radio monitoring and scientific management. Based on STM32 embedded platform, using the secondary frequency conversion chip MC13135 to receive and demodulate the modulated signal, a set of new wireless monitoring management equipment is designed, which embeds FFT algorithm to complete signal analysis. Measurement result shows that this analyzer can detect radio signal rapidly and accurately in management territory, real-time feedback the communication relative parameters and working characteristics of the measured signal.
