Operating Displays

A waterfall display as seen in Figure 6.3A displays the presence of signals as a series of lines each representing a scan across the frequency range. The strength of the signals or noise present is represented as the brightness, intensity, or color of the line at each frequency. As new lines are captured and displayed, the older lines are moved down or to one side, giving the impression of a “waterfall” as the information slows “flows” across the screen. [G2E12] Waterfall displays show the presence of any type of signal and a skilled operator can often tell what type of mode is in use from its appearance.
