Selecting Total as the power
control mode makes the total
power and C/N independent
variables while making the
carrier power and total noise
power dependent variables. The
dependent variables carrier
power and total noise power are
set by the total power, C/N, and
the rest of the Noise settings.
The carrier power and total
noise power change as any
noise parameter is adjusted to
keep the total power and the
C/N at their last specified
values.
Selecting Carrier as the power
control mode makes the carrier
power and C/N independent
variables while making the total
power and total noise power
dependent variables. The
dependent variables total power
and total noise power are set by
the carrier power, C/N, and the
rest of the Noise settings. The
total power and total noise
power change as any noise
parameter is adjusted to keep
the carrier power and the C/N at
their last specified values.
Selecting Total Noise as the
power control mode makes the
total noise power and C/N
independent variables while
making the total power and
carrier power dependent
variables. The dependent
variables total power and carrier
power are set by the total noise
power, C/N, and the rest of the
Noise settings. The total power
and carrier power change as
any noise parameter is adjusted
to keep the total noise power
and the C/N at their last
specified values.
