values for the respective portions of the band. These softpot values are then
programmed into the radio. Each configured channel’s RX Tune value is then updated
to reflect these new radio softpot values.
The following radio test report results are returned for the RX Tune alignment:
Name Description
Result Pass or Fail. This indicates whether the alignment succeeded.
Frequency Band Center frequency for the radio under test.
Low Old Band Low slope softpot setting before alignment.
Low New Band Low slope softpot setting after alignment.
Center Old Band Center softpot setting before alignment.
Center New Band Center softpot setting after alignment.
High Old Band High slope softpot setting before alignment.
High New Band High slope softpot setting after alignment.

Table 5-7. Analyzer Configuration for SQL Sensitivity Alignment
5.3.1. Alignment
The radio is set to receive at Test Channel 1 and the Audio Frequency volume is
changed by the software to an adequate level for receiver testing. After setting up the
analyzer according to Table 5-7, the radio’s first squelch point is sampled repeatedly,
averaged, and the result is programmed into the radio as the new squelch point softpot.
This process is repeated for each row in Table 5-7.
The following radio test report results are returned for the SQL Sensitivity alignment:
Name Description
Result Pass or Fail. This indicates whether the alignment succeeded.
Name Squelch point title.
Frequency Band Center frequency for the radio under test.
Power Level Signal generator output level for aligning this squelch point.
Old Softpot Old squelch point softpot setting before alignment.
New Softpot New squelch point softpot setting after alignment.
