Table 5-9. Analyzer Configuration for TX Power Alignment and Test
5.4.1. Alignment
The radio is set to Test Channel 6 and commanded to transmit by the software. Using a
best linear fit algorithm, several power measurements are taken with the analyzer and
used to determine the radio softpot value with a TX power closest to the alignment
target value found in APPENDIX C. Once the measurement closest to the target value
is found, the corresponding softpot is programmed into the radio. This process is
repeated for each TX Power point, including High (5 W), Low-High (2.5 W), Low-Mid (1
W), and E-Low (.25 W).
The following radio test report results are returned for the TX Power alignment:
Name Description
Result Pass or Fail. This indicates whether the alignment succeeded in bringing the radio
parameter into alignment limits as specified in the limits file.
Name TX Power point under test.
Frequency Band center frequency for the radio under test.
Max Limit Maximum passable power, inclusive, as specified in the limits file.
Power Measured power after alignment.
Min Limit Minimum passable power, inclusive, as specified in the limits file.
Old Softpot Radio parameter softpot value before alignment.
New Softpot Radio parameter softpot value after alignment.

5.4.2. Test
The radio is set to Test Channel 6 and commanded to transmit by the software. The
analyzer then samples the radio’s TX power. If the sampled TX power falls within the TX
Power test limit range for the power point under test as described in APPENDIX C, the
test is marked as pass. Otherwise, the test is marked as fail.
The following radio test report results are returned for the TX Power test:
Name Description
Result Pass or Fail. This indicates whether the alignment succeeded in bringing the radio
parameter into alignment limits as specified in the limits file.
Name TX Power point under test.
