Figure 6: Phoenix power level tuning menu
Connect the module jig RF output to the measurement instrument. In the EGSM band the pow-
er must be tuned in both high and low TX PA mode. In the two upper bands (GSM1800 and
GSM1900) there is only one mode.
For each band, tune the power by adjusting the coefficient in the Tx Power Level Tuning win-
dow in Phoenix until the target level is reached (measured on the spectrum analyzer). Remem-
ber to take into account the external power loss, i.e. the loss of the cable and the external
attenuator at the spectrum analyzer input. The coefficient must be tuned for the base level and
other levels, marked with bold letters in Phoenix (GSM900: PL19/15/7/5, GSM1800/1900:
PL15, 11, 0).
When the tuning has been completed, press Save & Continue to save the new tuning values
into the phone memory.
The following figure shows the power level tuning at the GSM900 band.
