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
• Agilent E9304A E-Series power sensor
