marker. If no frame number is specified, the marker is positioned on the currently
selected frame. All markers are visible that are positioned on a visible frame. Special
search functions are provided for spectrogram markers.
In the spectrum result display, only the markers positioned on the currently selected
frame are visible. In "Continuous Sweep" mode, this means that only markers posi-
tioned on frame 0 are visible. To view markers that are positioned on a frame other
than frame 0 in the spectrum result display, you must stop the measurement and select
the corresponding frame.
Color Maps
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
ESW.
The Color Scheme
●
Hot
Uses a color range from blue to red. Blue colors indicate low levels, red colors indi-
cate high ones.
●
Cold
Uses a color range from red to blue. Red colors indicate low levels, blue colors
indicate high ones.
The "Cold" color scheme is the inverse "Hot" color scheme.
●
Radar
Uses a color range from black over green to light turquoise with shades of green in
between. Dark colors indicate low levels, light colors indicate high ones.
●
Grayscale
Shows the results in shades of gray. Dark gray indicates low levels, light gray indi-
cates high ones.
The Value Range of the Color Map
If the measured values only cover a small area in the spectrogram, you can optimize
the displayed value range so it becomes easier to distinguish between values that are
close together. Display only parts of interest.
