AM Audio Path Offset Calibration

Description

This calibration is used to calibrate the AM path and remove any offset generated when LIN AM, LIN

BURST, or LOG BURST are enabled. This test determines the ALC_REF_DAC delta value which is used to

correct the offset when the modulation is enabled. This value is then stored in the appropriate calibration

constant.

Required Test Equipment

• Agilent E4418B E-Series power meter
