The waterfall analysis produces a three dimensional display of FFT spectra over time, frequency and amplitude. The waterfall display aggregates many single measurements to 40 displayed spectra. An updated measurement in the two-dimensional real-time FFT display only shows a fraction of the data, depending on the modulation method. In contrast the FFT waterfall display also displays data in the time domain

A time histogram is displayed on the left-hand side of the display.

By clicking on the graph, the display will be paused and measurement cursors appear.

Options can be set using the right mouse button or the context menu (see FFT/Sonagram Context Menu). It is possible to remove the tuning FFT or Sonagram in the View Menu.
