Transmit Power Alignment

Transmit Power alignment is required after replacing (or servicing) the transceiver board.
This alignment procedure adjusts the transmit power of the radio and must be performed for two
different power levels, at multiple frequencies for each power level, to allow for proper alignment
across the entire RF band. The RF band is divided into frequency zones with a calibration point
(value) in each zone.
• The same softpot attenuation value will result in DIFFERENT radio output power levels at
different frequencies.
• All power measurements are to be made at the antenna port.
1. Select the TX Power (High, Mid, or Low) alignment screen. The screen will indicate the
transmit frequencies to be used. See
