2. Connect the module jig RF output to the measurement instrument. The power must be tuned in only high
TX PA mode in all bands of GSM900, GSM1800 and GSM1900.
3. For each band, tune the power by adjusting the coefficient in the Tx Power Level Tuning window in Phoenix
until the target level is reached (measured on the spectrum analyzer). Remember to take into account the
external power loss, that is, 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 / 5, GSM1800/1900: PL15, 11, 0). The target power levels are specified as listed in the following table:

4. When the tuning for the levels marked with bold letters has been completed, press Calculate coefficients to
calculate the other power levels with non-bold letters.
5. When the coefficient calculation has been successfully done, 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.
