4.10.1. Alignment
Note: This alignment is only performed for APX 8000, APX 6000 Enhanced, APX NEXT,
and APX 900 portable 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 either -30 dBm or at -60
dBm. The radio softpot is then auto-aligned to minimize phase error. The results are
written to the test log file.
Pass or Fail. Pass unless radio reports an error.
Low/High side amplitude error (rad)
Low/High side phase error (rad)
Low/High side band suppression factor (APX
900 only)
