Study on Detection Technique of Complex Profile for High Speed Cutting

摘要

In the field of satellite communications, spectrum analyzer is one of the primary means of frequency monitoring, and it plays an important role in ensuring communication quality. According to the principle of the superheterodyne spectrum analyzer, the design and realization of a spectrum acquisition unit based on MSP430F149 MCU is given in this paper. Comparing the test results with those of the Agilent N9020 spectrum analyzer, the comparison shows that in the intermediate frequency signal monitoring, the spectrum analyzer designed in this paper has reached the current performance level of the mainstream spectrum analyzer.
