Spectrogram and Waterfall Displays
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 over time.
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 Waterfall display. However, it
also allows more traces to be viewed.
These two displays can NOT be used with Channel Measurements.
NOTE: Although this document refers to past traces as ‘records’ these traces are not
saved in Spectrogram and Waterfall displays. They are only drawn on the
FieldFox screen.
Spectrogram Display
Spectrogram draws the most recent trace record at the top of the stack of
previously-drawn trace records. Drawing the live trace on the display is
optional.
