4.8.1. Alignment
Note: This alignment is only performed for APX 900 models.
The Rx Front End Gain adjusts the radio’s RF front end for RSSI value correction.
The radio is placed into Test Mode at the first Rx Test Frequency. The analyzer
generates a CW signal at -75 dBm. The radio softpot is then auto-aligned. This
adjustment is performed for each Rx Test Frequency. The results for each Rx Test
Frequency are written to the test log file.
