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.

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.
The Shape and Focus of the Color Curve
The color mapping function assigns a specified color to a specified power level in the
spectrogram display. By default, colors on the color map are distributed evenly. How-
ever, to visualize a certain area of the value range in greater detail than the rest, you
can set the focus of the color mapping to that area. Changing the focus is performed
by changing the shape of the color curve.
The color curve is a tool to shift the focus of the color distribution on the color map. By
default, the color curve is linear. If you shift the curve to the left or right, the distribution
becomes non-linear. The slope of the color curve increases or decreases. One end of
the color palette then covers a large range of results, while the other end distributes
several colors over a relatively small result range.
You can use this feature to put the focus on a particular region in the diagram and to be
able to detect small variations of the signal.
