Modifying the Waterfall Color Gradient
The color gradient used for the Live Raster Waterfall can be customized by selecting colors for key
amplitude levels.
1. Tap the color gradient shown at the top left hand side of the Live Raster Waterfall screen. The
Waterfall Colors dialog box will appear. On the left side of the dialog box are two color controls
for selecting colors. The slider to the far left is used to select a hue. The color field to the right
of the hue slider is for adjusting the saturation and brightness of the selected hue. On the right
side of the dialog box is a gradient editor for mapping specific colors to key amplitude levels of
the waterfall color gradient.
2. To remove existing colors from the current color gradient, highlight the corresponding color
marker from the gradient editor on the right side of the dialog box by selecting it with the stylus,
then select the “-” marker at the bottom of the control.
3. To add a color to the color gradient, select the “+” marker at the top of the gradient editor on
the right side of the dialog box. This will place a new color marker at the center of the gradient
editor. Drag the new color marker up or down the gradient editor to modify the dBm value
represented by the color. Edit the color of the marker by using the color controls on the left
side of the dialog box.
