Displaying Graphs in Color Grade Mode

Displaying Graphs in Color Grade Mode

The Color Grade mode is much like using phosphor persistence on an
oscilloscope. The more a specific point is hit, the brighter it is displayed.
This quickly gives you a view of the distribution of points on the plots.

Color Grade is available during both acquisition and playback, and for the
following types of graphs:

Constellation charts

Eye diagrams (I-Q, Phase, Intensity, Magnitude, EVM)

Note: When going backwards in Playback mode, colors will be reset.

Note: Color Grade is applied to all relevant graphs at once. It is not available

when Averaging is active.

To activate Color Grade:
From the Display menu, select Color Grade. Clear the option to remove
the effect.
