Transmit power with ACM
Mean Constant Mode: All the selected ACM
profiles transmit the same output power level,
that is equal to the Maximum transmit power
indicated in the table above for the highest
modulation level selected.
Hybrid Mode: the ACM profiles above the
reference modulation transmit in Peak Constant
Mode (i.e. each modulation transmits the output
power indicated in the table above). Below the
reference modulation the Mean Constant Mode is
followed.
