Note:
1. 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.
2. To reduce random noise and aliases components in repetitive or single-shot events,
set the oscilloscope acquisition mode to average.
3. To display FFT waveforms with a large dynamic range, use the "dBVrms" scale. The
"dBVrms" scale displays component magnitudes using a log scale.
FFT Window
The ll provides four FFT windows. Each window is a trade-off between
frequency resolution and amplitude accuracy. It depends on the desired
