Setting Amplifier Capacity Metrics

Setting Amplifier Capacity Metrics
The Amplifier Capacity measurement is an estimate of the amount of power amplifier capacity that is being used, expressed in percent of maximum. Amplifier capacity properties must be properly set to make valid amplifier capacity 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]

13
Enter the Delta Sync Pwr in dB, using the numeric keypad.
The delta sync power is the power level of the the sync channel expressed as a dB value relative to the pilot channel power level.

14
[dB]
