Displaying individual frames
The spectrogram diagram contains all stored frames since it was last cleared. Arrows
on the left and right border of the spectrogram indicate the currently selected frame.
The spectrum diagram always displays the spectrum for the currently selected frame.
The current frame number is indicated in the diagram footer, or alternatively a time-
stamp, if activated. The current frame, displayed at the top of the diagram, is frame
number 0. Older frames further down in the diagram are indicated by a negative index,
e.g."-10". You can display the spectrum diagram of a previous frame by changing the
current frame number.

Color Maps
Spectrograms assign power levels to different colors in order 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
You can select which colors are assigned to the measured values. Four different color
ranges or "schemes" are available:
