TX Power tuning
This tuning must be done in both bands.
Note: TX Power tuning must be done with a peak power meter, e.g. Rohde & Schwarz model
NRVD with a Rohde & Schwarz Peak Power Sensor TDMA Model NRV-Z31 and a suitable
attenuator.
The use of power meter in GSM testers is likely to cause larger error than the use of a
dedicated power meter and might cause the phone to be non-compliant with GSM spec-
ifications.
