6.9.1. Alignment
Note: This alignment is only performed for APX 8500 and APX Mobile Enhanced
models.
See Motorola APX Family Tuner Help for a description of this alignment.
The radio is placed into Test Mode at the first Rx Test Frequency. Depending on the
radio model under test, the analyzer generates a CW signal at -60 dBm. The radio
softpot is then auto-aligned to minimize phase error. The results are written to the test
log file.
