TX power level tuning
Power Meter (or Spectrum analyzer) is needed.
With Tx power level tuning, the coefficients are adjusted for each power level.
Tuning must be performed separately on all band and all modes!
When EDGE is on, the tuning must be carried out for all power levels.
Tx power level tuning steps are:
• EGSM900 PA High Mode with EDGE off
• EGSM900 PA Low Mode with EDGE off (NOT IN USE FOR RH-12)
• EGSM900 PA High Mode with EDGE on
• EGSM900 PA Low Mode with EDGE on (NOT IN USE FOR RH-12)

• GSM1800 PA High Mode with EDGE on
