Chapter 3 Configuring Platform Parameters Configuring QAM-RF Modules Power Level (dBmV) - The power level of the RF port. Once you define the RF power level, the power level of all QAM channels in the port changes accordingly. All QAM channels have the same power level in relation to the defined power level of the RF port. Once you configure the power level in dBmV, you can view the power level also in dBuV. Power Level Per QAM - define the QAM power level for all QAM channels within the port. This value appears in the QAM tab as a read-only value. Once you configure the power level per port in dBmV, you can view the power level per port also in dBuV. NOTE: Any changes to the RF power level affect the QAMs power level and vise versa. 5. Review the port and its QAM channels configuration via the provided bar graphs as explained in the following section. 3.12.3.1 Understanding the RF Port Graph A bar graph, for each RF port displays the current configuration of the RF port as the following table explains: Licensed QAM channel Licensed Mute QAM channel No license RF port disabled - red grid RF port enabled - blue grid Applied spectral inversion No license, CW applied Licensed, CW applied Licensed QAM channel Table 3-8: RF Port Legend RF Enable Parameter Blue grid - RF port is enabled Red grid - RF port is disabled Explanation # QAMs per Port Number of bars in graph. Each QAM-RF channel is represented by a bar. Power Level (dBmV) Height of bar. Each bar represents a QAM, however the power level of each QAM depends on the RF port power level. © 2012 Harmonic Inc. 48 NSG 9000-6G, Version 2.7, Rev B
Chapter 3 Configuring Platform Parameters Configuring QAM-RF Modules Table 3-8: RF Port Legend Bar color Bar shape Parameter Blue - license is granted and QAM is active Light shade of blue - license is granted and QAM is mute. Gray - no license is granted Light shade of gray - no license and QAM is mute. Rectangle like - normal Pointy bar - CW is activated Truncated bar - channel is mute. Explanation Indicates that spectral inversion is applied on this QAM. The arrows appear at the top of the bar. Once you hover the mouse pointer over a bars you can read QAM channel related information as the following table explains: Table 3-9: Hint Explanation Hint Parameter Frequency Power level Mute Spectral Inversion CW Signal QAM License Explanation Indicates the center frequency of the QAM-RF channel Indicates the power level of the QAM-RF channel Indicates whether mute or not Indicates whether spectral inversion is applied Indicates whether CW is applied or not Indicates whether QAM license is granted 3.12.4 Configuring/Viewing QAM Channels 1. Select the Platform tab. 2. In Back Panel View, select the required slot. © 2012 Harmonic Inc. 49 NSG 9000-6G, Version 2.7, Rev B
