Set settings for pulse power meter
All four tuning channels have to be tuned. Repeat tuning for A, B, C and
D tuning channel. Tuning channel change read old tuning values from
phone's EEPROM.
Adjust power level by clicking the + and – buttons, power level change is
done by keyboard keys
Tune power levels, which are shown by "# for calculate"
Press Calculate button to calculate other power levels.
Check tuning, Do fine tuning if needed.
Once all TX tuning channels are correct, press SAVE button
Tuning done, if both Analog mode and 800 MHz and 1900 MHz digital
mode tuned
Difference between measured TX power from Test Pad of panel and
Antenna Pad, must be taken care so that measurements from An-
tenna Pad give the correct results.
