Troubleshooting
Verify that the signal on RIF N702 Pin 17 (TP108) shown in the plot above is present on
CAFÉ Pin 24 (TP110). If this is the case then check the test set up.
800 CDMA Tuning Tx IF AGC
Description of Test
The RIF and TIF AGC is approximately a second order curve. This curve is split into 16 seg-
ments for both Transmitter and Receiver. Offset and slope values are stored in eeprom for
each of these 16 segments. The offset for the segments is computed from the 3–point
calibration performed in this test. After test a 2
Offset and Slope computed. TX_IF_AGC must be adjusted to achieve the correct power
level for Point 1, when this is done the process must be repeated for Points 2 and 3.
Definition of Result
The results of the 3 point tuning are the 16 slope and offset values, which are stored to
eeprom RF_TUNE_CELL_TX_AGC_OFF-SET_ SLOPE_HANDLE.
