7.2 Tilt Analysis
Overview:
Tilt measurement is used to check the channel levels at the lowest and highest frequencies because level variations across the frequency
spectrum are indicative of distortion. Tilt measurement is also the most efficient tool for balancing distribution amplifiers. By tapping on the
channel bars to select a channel then press the Enter key, the Tilt measurement will measure the two most recently selected channels.
Typically, the same analog and digital channels which have been recommended or defined for the Scan function should be used when
performing Tilt measurements. Often, Tilt measurements are useful to identify excessive cable lengths at the customer premises that can
cause high frequency roll off.
The CX380S-D3.1 measures up to 8 analog and 8 digital channels simultaneously. Normally, the tilt is measured from the lowest
frequency channel to the highest frequency channel; however, the user can select any two channels to measure their tilt by tapping on the
channel in the bar graph. The selected channel’s bar graph will change to Yellow.
Press the ENTER key on the keypad to engage the selected channel.
