Persistence and color maps
In addition to the standard representation, the vector, the constellation, and the power
spectrum diagrams use a color map.
The color encodes the relative amplitude (in percent) of the probability distribution of
the data points in the diagram. A detailed breakdown of the colors is below diagrams
the colors are relevant for. Data points in areas with high probability are marked in red,
data points in areas with low probability in blue. Thus, for example, you can observe
not only the "level versus frequency" trace but also a third dimension, the probability of
the power level.
Reference trace
Reference traces help you analyze a displayed characteristic, as do the markers. Ref-
erence traces are used to define amplitude curves or spectral distribution boundaries in
the result diagram which are not to be exceeded. They indicate, for example, the upper
power limits which are allowed from a device under test (DUT).
The R&S
SMM100A supports up to five reference traces. You can load reference
traces and activate them simultaneously.

Graphics configuration settings
This section focuses on the graphics configuration dialog, which determines the num-
ber and kind of the graphical signal displays.
Access:
1. Select "Taskbar > System Config > Graphics" or use the wave icon.
The "Graphics Configuration" dialog opens.
