Tx power level tuning
Context
Because of variations in the IC process and discrete component values, the actual transmitter RF gain of each
phone is different. Tx power level tuning is used to find out mapping factors called 'power control
values’ (PCV). These factors adjust the WLAN transmitter output power to fulfill the required specifications.
Steps
1.
Connect the phone to the WLAN measurement equipment.
2.
From the dropdown menus, set "Operating mode" to Local.
3.
From the Tuning menu, choose "WLAN Tx Tuning".
4.
Adjust the measurement equipment for power level tuning. Remember to take jig and RF cable
attenuations into account!
5.
Choose Data rate 6 Mbit/s. It should be 6 Mbit/s, otherwise power levels for other datarates will
be miscalculated!.
6.
Click Start.
