2. Check the level of the RF output signal (as determined in Section 2.6) against the system
design plan specifications. Table 4-1 shows the output signal level required to provide 5
watts per channel for systems with 1 to 2 channels. The maximum output signal level
permitted for the system is 40.5 dBm (11 Watts).
3. Determine if more or less attenuation is required to produce the required output signal level.
4. Right-click on the Remote Fwd Att section of the display (see Figure 4-10). The Remote
Fwd Att pop-up screen will open as shown in Figure 4-11.
5. Enter the required attenuation value and click OK to close the pop-up screen and to make
the changes take effect.

When there are three or more channels, each
channel will always be less than 5 watts since
the system has a maximum power output of
11 watts (40.5 dBm).
