The FFT will appear on the display.
Quick Tips
Use short record lengths for faster instrument response.
Use long record lengths to lower the noise relative to the signal and increase the frequency resolution.
If desired, use the zoom feature along with the horizontal
Position
and
Scale
controls to magnify and position the FFT
waveform.
Use the default dBV RMS scale to see a detailed view of multiple frequencies, even if they have very different amplitudes. Use
the linear RMS scale to see an overall view of how all frequencies compare to each other.
