Markers in three-dimensional spectrograms
In three-dimensional spectrograms, the markers are indicated by the common arrows
used in the spectrum display, for example. New markers are automatically placed on
the current frame. You can move the markers to any position in all dimensions of the
diagram. When you select a marker on the screen, three-dimensional cross-hairs indi-
cate the position on all axes.
Sometimes, a marker can be hidden by other frames. If necessary, rotate the spectro-
gram or select a different frame as the current frame.
Color Maps
Spectrograms assign power levels to different colors to visualize them. The legend
above the spectrogram display describes the power levels the colors represent.
The color display is highly configurable to adapt the spectrograms to your needs. You
can define:
●
Which colors to use (Color scheme)
●
Which value range to apply the color scheme to
●
How the colors are distributed within the value range, i.e where the focus of the vis-
ualization lies (shape of the color curve)
The individual colors are assigned to the power levels automatically by the R&S FSW.
The Color Scheme
●
Hot
Uses a color range from blue to red. Blue colors indicate low levels, red colors indi-
cate high ones.
