12. AUTO CALIBRATION
12.1 Overview
AutoCal (Auto Calibration) is the PC side calibration tool that performs Rx and Tx calibration with
Agilent 8960 or other equipment. AutoCal generates calibration data by communicating with phone
and measuring equipment and writes it into calibration data block of flash memory in GSM phone.
There are three steps for automatic gain control (AGC) for Rx, automatic power control (APC) for
Tx, and ADC control for monitoring battery voltage.
