Display settings
Access: [App Cockpit]> "Analysis" > "DDR Eye" > "Display" tab
In the "Display" tab, you define the appearance of the individual eye diagrams.
You can configure and analyze up to four independent eye diagrams in parallel (vertical
subtabs E1 to E4). Make sure to select the correct eye diagram subtab on the left
before you adjust the settings.
Color table assignment
Like any other waveform, you can show the eye waveform in solid color, or apply a
color table. If you select solid color, the intensity of the waveform is proportional to the
number Z of waveform slice points that hit a point (X,Y).
Chapter 4.3.2, "Color tables", on page 98.
