Design of Virtual Signal Spectrum Analyzer Based on LabVIEW

In our report,the virtual signal spectrum analyzer based on LabVIEW was designed,and the test was performed successfully.Amplitude signal frequency which is less than 50 kHz and voltage which is lower than 5 V could be analyzed by the virtual spectrum analyzer.Waveforms collected were processed by the corresponding program module,and the waveform frequency,amplitude,mean,RMS and other information could be obtained.Waveform signal,the signal parameter information and the waveform of the spectrum analysis module could be saved in the form of statements.The results showed that the analysis data with the spectrum analyzer is correct,and the program runs smooth.
