AM Audio Path Offset Calibration
Description
This test calibrates the AM path to 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
• HP/Agilent 438A Power Meter
• HP/Agilent 8482A Power Sensor
