Frequency Analysis
The result of FFT (Fast Fourier Transform) calculations is the frequency
spectrum of the source signal. The horizontal axis of the FFT display is
labeled using frequency (Hz) units instead of time (seconds). In addition,
the vertical axis provides the option of logarithmic scaling
(dBVrms/dBArms or dBm). In this mode, the oscilloscope display is very
similar to a spectrum analyzer.
