1900 PCS Tuning Rx IF Compensation
Description of Test
In this tuning, the receiver is calibrated at five different frequencies across the band.
WinTesla instructs the signal generator to be set at five specific frequencies and a fixed
amplitude. The RX_IF_AGC is adjusted by the phone’s software to make the best use of
the CAFE ADC. The setting of RX_IF_AGC then is read from the phone at each of the five
frequencies.
Definition of Result
The five different values of RX_IF_AGC are stored to EEPROM.
