Chapter 3 Configuring Platform Parameters<br />
Configuring QAM-RF Modules<br />
<br />
<br />
Power Level (dBmV) - The power level of the RF port. Once you define the RF power<br />
level, the power level of all QAM channels in the port changes accordingly. All QAM<br />
channels have the same power level in relation to the defined power level of the RF<br />
port. Once you configure the power level in dBmV, you can view the power level also<br />
in dBuV.<br />
Power Level Per QAM - define the QAM power level for all QAM channels within the<br />
port. This value appears in the QAM tab as a read-only value. Once you configure the<br />
power level per port in dBmV, you can view the power level per port also in dBuV.<br />
NOTE: Any changes to the RF power level affect the QAMs power level and vise versa.<br />
5. Review the port and its QAM channels configuration via the provided bar graphs as<br />
explained in the following section.<br />
3.12.3.1 Understanding the RF Port Graph<br />
A bar graph, for each RF port displays the current configuration of the RF port as the following<br />
table explains:<br />

Explanation<br />
# QAMs per Port Number of bars in graph. Each QAM-RF channel is represented by<br />
a bar.<br />
Power Level (dBmV)<br />
Height of bar. Each bar represents a QAM, however the power<br />
level of each QAM depends on the RF port power level.<br />
