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 Maximum Deviation 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 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.
Softpot Current radio parameter softpot value.

Table 5-15. Analyzer Configuration for Sub Audio Deviation Alignment and Test.
5.6.1. Alignment
The radio is set to Test Channel 4 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 target value
found in APPENDIX C. Once the measurement closest to the alignment target value is
found, the corresponding softpot is programmed into the radio. This process is
performed for each Sub Audio Deviation point in Table 5-15: CTCSS Wide (CH 04),
CTCSS Narrow (CH 05), DCS Wide (CH 07) and DCS Narrow (CH 08).
The following radio test report results are returned for Sub Audio 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 Sub Audio Deviation point under test.
Frequency Band center frequency for the radio under test.
Max Limit Maximum passable sub audio deviation, inclusive, as specified in the limits file.
Deviation Measured deviation after alignment.
Min Limit Minimum passable sub audio deviation, inclusive, as specified in the limits file.
Old Softpot Radio parameter softpot value before alignment.
New Softpot Radio parameter softpot value after alignment.
