Dynamic Power Control Configuration
Dynamic Power Control (DPC) is a Vipersat feature that acts to regulate the
transmit power of the Vipersat satellite modem, such that the specified receive
signal level (E
b
/N
0
) for the Vipersat unit(s) receiving the transmission is met.
DPC is driven by the receiver demod, which periodically notifies the transmit-
ting modem of the current E
b
/N
0
value that it is receiving.
Refer to Appendix C “Dynamic Power Control” in this document for additional
information on the DPC feature.
The Dynamic Power Control configuration page, accessible from the Vipersat
submenu, allows for setting the parameters for the SLM-5650A power levels.
The information and commands in the menu will vary depending on the func-
tion that the target SLM-5650A performs in the network. The screen shown in
figure 3-41 is for a Hub or Remote operating in SCPC mode. For comparison,
the DPC configuration screen for a unit operating as a Hub Expansion Demod
(SCPC mode) is shown in figure 3-42. Note that only the applicable settings
appear in this screen.
