7.3.4 DCS 1800 Calibration Items
A. DCS Ramp Up/Down Calibration
- Purpose
This item contains the DCS normal Tx burst up/down-ramp DAC values for each power level.
When a DCS Tx burst is generated, it shall pass the ETSI standard power mask as well as Output RF
Spectrum due to Modulation and Switching (OSRF).
- Procedure Proposal
1. Set phone to DCS mode. Determine the DAC codes for each power level during steady state (flat
part of the burst). Each power level has a tolerance limit as shown in Table 7-2.
2. Let’s call X the power levels and Y(x) (i) the up ramp DAC value of X power level at iteration i ( we
have 30). We then have the following:
NV_DCS_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_DCS_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_DCS_TX_BURST_UP_RAMP_INDEX_X[X, Y(x) (i)] to an NV file.
