Minimum Power
The set value for the Minimum Power is the minimum level allowed by all
SCPC modulators. Using the values entered in the Home State dialog (see
“Home State” on page 2-52) together with the value entered for the Maximum
Power, the modem scales the Maximum Power to optimize the E

o
for what-
ever data rate the unit is transmitting. For this reason, it is recommended that the
Minimum Power be set to the lowest possible setting (-40.0 dBm), giving the
power adjustment the largest possible working range.
In the majority of applications, the minimum power level parameter can be set
to the default power value of -40.0 dBm. Typically, there is no problem in
allowing the modulator(s) to back off decreasing power levels to better the qual-
ity of link conditions.
