Tx Power Level Tuning - Nokia RH-37 Series Service Software And Tuning Instructions

Nokia Custome Care
The notch value might not be displayed in later Phoenix versions.
Press Tune and the optimal values are found.
Press Stop, the values are saved to the phone and the calibration has finished.
The results must fulfill the following limits:
Calibration value / Test case
DTOS I Address Rc / check rx baseband
filter DTOS_I
DTOS Q Address Rc / check rx baseband
filter DTOS_Q
BBF I Address BIQUAD I R / check rx baseband
filter BIQUAD_IR
BBF I Address BIQUAD I C / check rx baseband
filter BIQUAD_IC
BBF Q Address BIQUAD Q R / check rx baseband
filter BIQUAD_QR
BBF Q Address BIQUAD Q C / check rx baseband
filter BIQUAD_QC
Notch / check rx baseband filter NOTCH

Note: In later Phoenix versions the notch calibration might not be applicable anymore.

TX power level tuning

RH-37 supports GMSK and EDGE mode for the Power amplifier. Therefore, the power
level tuning must be carried out for both modes in each band.
It is strongly recommended to use the Phoenix <Auto-Tune> capability. The functional-
ity of it is described in chapter "Fully automatic Calibration, Tuning & Measurement
by Phoenix <Auto-Tune>".
It is strongly recommended to use TXP as external trigger for all TX tunings. External trig-
gering gives the following advantages:
• trigger for spectrum analyzer (gated sweep)
• trigger for oscilloscope
• trigger for power meter (avoid exchanging of attenuator and getting better accu-
racy in power measurements)
Nevertheless, manual tuning is described below. It has to be carried out in all three bands
and both modes (EDGE and GMSK).
