4.9.1. Alignment
Note
: This alignment is only performed for APX 900 portable models.
The Rx Front End Filter adjusts the radio’s Rx VLIF DCA Phase Error.
The radio is placed into Test Mode at the first Rx Test Frequency. The analyzer
generates a CW signal at -15 dBm into the radio. The radio softpot is then auto-aligned.
This adjustment is performed for each Rx Test Frequency available. The results for
each Rx Test Frequency are written to the test log file.
