specified amount of power allocated to the CPICH (Common Pilot Channel). The
specified power settings of the PCCPCH (Primary Common Control Physical
Channel) are defined relative to the CPICH. Occasionally, the PCCPCH power
setting will also be specified in absolute power units (watts or dBm). Given the
CPICH and PCCPCH setup values and the maximum power output of the amplifier,
the percentage amplifier capacity setup parameters can be determined.

6 Enter the maximum power
amplifier power in watts,
using the numeric keypad.
A base station power amplifier is specified to
have a maximum power limit.
7 [CPICH Pwr] CPICH refers to Common Pilot Channel.
8 Enter the CPICH power in
watts, using the numeric
keypad.
The CPICH power is the total power in the
dominant pilot signal, expressed in watts.

10 [Δ (Delta) PCCPCH...] PCCPCH refers to Primary Common Control
Physical Channel.
11 Enter the Δ (Delta)
PCCPCH Pwr in dB, using
the numeric keypad.
The Δ (Delta) PCCPCH is the expected
amplitude difference between the PCCPCH
channel and CPICH channel, expressed in dB.
