ALC Modulation Flatness Calibration
Description
This test calibrates the ALC REF DAC corrections necessary to maintain power flatness in
the ALC open-loop mode of operation. The nominal ALC REF DAC settings are adjusted to
re-align the ALC open-loop power with the desired level. The resulting values are stored as
calibration arrays in the signal generator’s firmware.
Required Test Equipment
• HP/Agilent 438A Power Meter
• HP/Agilent 8482A Power Sensor
