- 179 -
NV_GSM_1900_TX_BURST_UP_RAMP_INDEX_X = (X, Y(x) (i) ), where X is a power level
For Power Control Level X= 5 to 19
For i = 1 to 30 (Number of step for Ramp Up)
NV_GSM_1900_TX_BURST_UP_RAMP_INDEX_X[X, Y(x) (i)] = DCS_PA_DAC_CODE[X] -
DAC Table [X,Y(x) (i)]
Next i
Next x
3. Turn PA off
4. Write NV_GSM_1900_TX_BURST_UP_RAMP_INDEX_X[X, Y(x) (i)] to an NV file.
B. PCS Freq. Comp. Calibration
- Purpose
This item contains the change in Tx power of 15 ARFCN (Absolute Radio Frequency Channel
Number) relative to a reference ARFCN (channel 633).
NOTE 15 ARFCN + 1 ref channel = 16 channels.
- Procedure Proposal
1. Load the highest PCS power as defined in the standard.
2. Measure frequency response of the phone across 16 different ARFCN.
3. The data structure for all Tx frequency-compensated NV items are laid out as in the following
example.
NV_GSM_1900_TX_FREQ_COMP
-8,-2,0,3,5,5,-7,-6
NOTE The first data index will correspond to channel index 0 and so on until the last index is reached
for all channels. The data point for the reference channel will always be 0.
C. PCS RX Gain Range Calibration
- Purpose
This item specifies the RX gain from the antenna to the MSM for 16 frequencies in the PCS band.
- Procedure Proposal
Same as in previous section in GSM except this time set the gain range and phone mode to PCS with
injected power of -65 dBm. In DCS we will frequency compensate over 16 channels.
