Tilt Measurement

The Tilt measurement helps to quickly measure the flatness of a CATV system and the gain of the splitters /
taps. This feature provides power levels for up to 16 channels. Upon entering the Tilt function, you will be
prompted to set the tilt plan. Select 4 - 16 channels from the channel plan window, then tap outside the
window to start the measurement.
There are 2 markers, displayed as color-coded vertical lines, on the Tilt screen. Tap-and-drag a marker to
move it left or right, or tap-and-drag the display up or down to change the reference level. When you
move a marker over a channel in this way, its level and channel type are displayed.
The Tilt measurement has two different view modes. Tap [Graph/List] to toggle between them.
