Quick Tips:
If desired, use the zoom feature to magnify the FFT waveform.
Use the default dB scale to see a detailed view of multiple frequencies, even if they have very different amplitudes.
Use the Vrms scale to see an overall view of how all frequencies compare to each other.
Signals that have a DC component or offset can cause incorrect FFT waveform component magnitude values. To
minimize the DC component, choose AC Coupling on the source signal.
To reduce random noise and aliased components in repetitive or single-shot events, set the oscilloscope
acquisition mode to average.
