1. FFT Spectrum Analyzer
The FFT process mathematically converts a time-domain signal into its frequency
components. You can use the Math FFT mode to view the following types of
signals:
● Analyze the Humorous wave in the Power cable.
● Test the Humorous content and distortion in the system
● Show the Noise in the DC Power supply
● Test the filter and pulse response in the system
● Analyze vibration
