Repeat steps 4 to 9 for all bands. On those bands only power levels 0, 11 and 15 need to be tuned.
Tuning TX/IQ
Context
The tuning must be carried out in all three bands. In addition to Phoenix, a spectrum analyzer (SA) is needed.
Steps
1. Connect the spectrum analyzer (SA) to the RF connector of the module jig. The settings of the SA will depend
on the band to be tuned. The following table summarizes the settings for each of the three bands.
