Color-Grade
Color-Grade mode uses color in the displayed waveform to show which values are most frequent
in the waveform sample. Normally, display intensity is varied to give you hints about the most-
frequent values. Color-Grade mode instead uses color to represent the relative frequency of
voltage or current values appearing in the waveform (it is similar to a histogram).
Colors near red have the highest relative frequency and colors near blue have the lowest. For
signals with random noise, Color-Grade mode is useful in helping you qualitatively understand
the stochastic nature of the signal being measured.
The intermediate colors are ordered similarly to the spectrum of white light:
