Color mode persistence, selected by touching  , works on the same principle as the Analog 
persistence feature, but instead uses the entire color spectrum to map signal intensity: violet for 
minimum population, red for maximum population. A saturation level of 100% spreads the intensity 
variation across the entire distribution; at lower saturation levels the intensity will saturate (become 
the brightest color) at the percentage value specified. Lowering this percentage causes the pixels 
to be saturated at a lower population, and makes visible those rarely hit pixels not seen at higher 
percentages. 
3-Dimensional Persistence 
By selecting 3d 
 , you can create a topographical view of your waveform from a selection of 
shadings, textures, and hues. The advantage of the topographical view is that areas of highest and 
lowest intensity are shown as peaks and valleys, in addition to color or brightness. The shape of the 
peaks (pointed or flat) can reveal further information about the frequency of occurrences in your 
waveform. 
The instrument also gives you the ability to turn the X and Y axes of the waveform through 180° of 
rotation from -90° to +90°. 
Here is an example of a 3-dimensional view of a 
square wave using the solid view of color-graded 
persistence. Saturation is set at 50%, with red 
areas indicating highest intensity. The X-axis has 
been rotated 60%; the Y-axis has been rotated 
15%.
