5-6 Configuring the Constellation Radio
ATPC High/Low Configuration
Constellation operates at one of two TX output power levels: ATPC High and
ATPC Low. These levels are set during calibration by using the keypad.
The high power setting can be as much as 7.5 dBm below the rated power
during calibration. So, the power can be reduced by calibrating ATPC High at a
value that is no more than 7.5 dBm below the rated power.
The radio can also be set to 10 dBm below the rated power by calibrating ATPC
High at rated power, calibrating ATPC Low at 10 dB lower than rated power,
then selecting “ATPC disabled low” to operate 10 dB below rated power.
If necessary, the ATPC Low setting can be calibrated between 2.5 dB and 10 dB
below rated power by selecting “ATPC disabled low.”
Pads are required to operate at more than 10 dB below
rated power.
