Spectrogram and Waterfall displays provide a visual history of the measured spectrum. Each display type can be used to locate intermittent signals or to view signal levels and frequencies over time.
A Spectrogram is a single horizontal line of color-coded power, while Waterfall uses a 3-D color-coded display. The functional difference between these two displays is that Spectrogram provides less trace detail than the Waterfall display. However, it also allows more traces to be viewed.
These two displays can NOT be used with Channel Measurements.
Traces can be recorded from, or played back into, any measurement type (such as Channel Power or Occupied BW) or any display type (such as Spectrogram and Waterfall).
