Table 5-12. Analyzer Configuration for Maximum Deviation Alignment and Test
5.5.1. Alignment
The radio is set to Test Channel 1 and commanded to transmit by the software. Using a
best linear fit algorithm, several deviation measurements are taken with the analyzer
and used to determine the radio softpot value with a deviation 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
performed for each Maximum Deviation point in Table 5-12: Wide (CH 01), Narrow (CH
06), and Digital (CH 09).
The following radio test report results are returned for Maximum Deviation 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 Maximum Deviation point under test.
Frequency Band center frequency for the radio under test.
Max Limit Maximum passable deviation, inclusive, as specified in the limits file.
Deviation Measured deviation after alignment.
Min Limit Minimum passable deviation, inclusive, as specified in the limits file.
Old Softpot Radio parameter softpot value before alignment.
New Softpot Radio parameter softpot value after alignment.

5.5.2. Test
The radio is set to Test Channel 1 and commanded to transmit by the software. The
analyzer then samples the radio’s maximum deviation. If the sampled deviation falls
within the Maximum Deviation test limit range for the deviation point under test as
