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 />
