4.3.1. Alignment
The TX Power Out alignment is composed of two parts: Tx Power Characterization
Points tuning and Tx Power Characterization tuning.
Power Characterization Points tuning adjusts the characterization points to account for
the variability of the power detection circuitry between radios. The radio is placed into
Test Mode and commanded to transmit at the first Test Frequency. The output level is
measured and then adjusted until near to a band-specific output level defined by the
APX Tuner software help file.
This process is repeated for all test frequencies. The final results are written to the log
file.

Table 4-7. Power Characterization Points alignment results
Power Characterization tuning characterizes the power output level of the radio. The
radio is placed into Test Mode and commanded to transmit. Beginning at the lowest TX
Test Frequency, the output level is measured at two different points for each TX Test
Frequency. These measurements are used to calculate and program power coefficients
use to normalize the radio power output level across the radio band as specified by the
radio’s basic service manual.
This process is repeated for all test frequencies. The final results are written to the log
file.
