measurements. Amplifier capacity metrics are amplifier capacity, peak amplifier
capacity, and average amplifier capacity.
A CDMA base station is typically set up with a specified amount of power allocated
to the pilot channel, and specified power settings of the paging and sync channels
are defined relative to the pilot channel. Occasionally, the paging and sync channels
power settings will also be specified in absolute power units (watts or dBm). Given
the pilot, paging, and sync power setup values and the maximum power output of
the amplifier, the percentage amplifier capacity setup parameters can be determined.

Step Notes
1 [Reset/Display/Amp Cap]
2 On [Amp Cap] select
On.
3[Pilot Pwr]
4 Enter the pilot power in
watts, using the numeric
keypad.
The pilot power is the total power in the
dominant pilot signal, expressed in dBm or in
watts.
5 [dBm] or [W]
6[Max PA Pwr]
7 Enter the maximum power
of the power amplifier in
watts, using the numeric
keypad.
A base station power amplifier is specified to
have a maximum power limit.
8 [dBm] or [W]
9 [Delta Page Pwr]
10 Enter the Delta Page Pwr in
dB, using the numeric
keypad.
The delta paging power is the power level of
the paging channel expressed as a dB value
relative to the pilot channel power level.
11 [dB]
12 [Delta Sync Pwr]
