Inputs / Cursors / Range / Axis control panel: This menu provides controls for inputs, cursors, and
frequency range settings. Horizontal +/- buttons are used to select the span of the X (frequency) axis
(zooming in/out). The vertical +/- buttons change the Y (amplitude)-axis range.
Graph area: Here, the currently calculated signal spectrum is plotted in the selected frequency range.
Waterfall plots: Waterfall plots are a different way of the signal spectrum representation where the
color on the plot defines the signal amplitude for a certain frequency. The waterfall plot is also useful to
enable the representation of a signal spectrum in a time dependency.
3.2.1. Features
The main features of the DFT Spectrum analyzer are described below:
3.2.1.1. INPUTS
Inputs controls are shown in the picture below. With the "SHOW" select button displaying the spectrum
of the selected input can be enabled or disabled. The "FREEZE" button is used for stopping the
measurements of the selected input. The "MIN" and "MAX" select buttons are used to enable/disable
the persist mode for the spectrum plot. The "MIN" signal spectrum plot will show the lowest values of
the signal spectrum taken after enabling the "MIN" button. The same logic is used for the "MAX" signal
where the MAX values of the signal spectrum are shown. This feature is mostly used for detecting signal
glitches and the max/min spectrum amplitude values during the measurement.
3.2.1.2. CURSORS
The cursors are an additional vertical and horizontal pair of lines useful for extracting the values of the
spectrum plots. The cursors are interactive and they can be set on any part of the graph while the
