3. Tx Power Tune up Procedure
1) Procedure:
a. Calibraion equipment HP8960 and the cell phone are connected through
RF cable.
b. Target power ( required power level according to the specification which
should be set by calibration program) is set to equipment as power level
(ex: GSM 5 level is 32.5 dBm).
c. Activate phone in Tx_Mode_Only.
d. HP8960 equipment measures transmitted power through rf test cable from
the phone and reports measured level to calibration program.
e. The program compares measured power with the target power.
f. The calibration program decides power code which is defined in advance
in the program and writes the codes to the flash memory in the phone.
2) Target value is defined according to the value of GSM specification.
See the TX power level definition table below.
3) Target values of the peak level of the phone are set normally in conducted
mode
–GSM 5 level : 32.5dBm
- PCS 0 level : 29.5dBm (Tolerance : -2dB ~ +1dB )
4) Accuracy
All the TX level from the phone after tuned-up satisfy the GSM
specification
5) TX ramp mask specification applied to the calibration program:
