Realization Of Spectrum Analysis And Remote Monitoring Based On MxL214C

Spectrum analysis is the diagnosis of the signal.On the basis of analyzing the frequency characteristics,the possible danger is found and the cause of the fault is diagnosed.So that the system parameters can be identified and corrected.With the application of spectrum analysis technology in more fields,the shortboards of traditional spectrum analyzers are gradually exposed.They are difficult to adapt to complex field changes and can not achieve real-time monitoring.This paper systematically describes the design process of spectrum analysis and monitoring system based on RF processing chip,and realizes the remote monitoring of radio and television network signals.Firstly,ADS software is used to design and simulate the dual transmitter to complete the filtering of the radio frequency signal.The purpose is to limit the frequency band of the signal to the processing range of the radio frequency chip.Firstly,using ADS software to design and simulate the dual transmitter,the filtering process of radio frequency signal is completed.The purpose is to limit the frequency band of the signal to the processing range of the radio frequency chip.Then the circuit design of the RF processing module with the MxL214 C and the demodulation module are completed.Realize the amplification,tuning,filtering and demodulation of radio frequency signal.Finally,the software monitoring system based on BS architecture is developed by using Java language,which successfully demonstrates the spectrum analysis and remote monitoring of signals.Compared with the traditional spectrum analysis method,the system has obvious real-time performance.It is not only convenient for flexible field information acquisition,but also improves the efficiency of signal diagnosis.It will be the development trend of spectrum analysis monitoring system in the future.
