The resulting image shows the measured levels as different shades of color. The color
range depends on the
color scheme you have selected.
●
For reflection measurements, the image shows the reflectivity in dB. Each color
shade corresponds to a certain reflectivity value.
●
For transmission measurements, the image shows the transmission attenuation in
dB. Each color shade corresponds to a certain attenuation value.
A color map next to the image shows the levels that correspond to each shade of color.
All images show the perspective as seen from cluster 1.
For all measurements, the x- and y-axis show the dimensions of the image in mm
(200
mm x 200 mm by default). Note you can change the scale of the x- and y-axis
using a mouse. The default value is restored after a new measurement.
A blue rectangle that is superimposed on the image indicates the part of the image that
is evaluated for the
numerical results . The size and location of this evaluation window
depends on your configuration.
