Spectrum Menu

The FFT screen display can be changed to use a number of different ways of scaling the Y-axis through the spectrum menu.

   

The available scaling options are Power (V²), Magnitude (mV) and Phase (Rad). As indicated in the FFT Overview section, by clicking the blue area on the axis of the FFT plot, the units can be changed between linear and logarithmic for each of these settings.

The default spectrum is Magnitude.
