No input means that the power require-ment for a station loop is calculated. The last line states the required amplifier power includingthe station output back-off.Figure 3-20 Link Budget Tool - Summary Worksheet DownlinksThe second part represents the power requirement considering all downlinks to reachable sta-tions. For fully meshed stations this includes all stations in the network; for remote terminals instar networks only the downlinks to the two hub stations are considered. Here the ’Power alllinks and channels’ output represents the required amplifier power including output back-off.The ’ODU all links’ output field proposes the amplifier power class according to the definitions
