User guide
The contour plot shows discrete lines of equal bit error rate - just like the
contour lines on a map. The color of a line indicates the respective BER value.
This graph is useful to visualize in which areas the BER changes - a
homogeneous BER field will give you no lines at all.
•
Pseudo Color Plot
This plot visualizes the BER by a continuous color gradient. It uses different
colors for the regions between the lines of equal BER. This is useful to get an
immediate visual impression of the distribution of the BER in the eye diagram.
• Equal BER at BER threshold
This graph displays only one curve for the chosen bit error rate threshold.
