ALC On/Off

ALC On/Off, available from the Soft Front Panel, is used to enable or

disable the ALC.

In this configuration, when the ALC is off (disabled), power is not

sensed at any point, and the absolute power level is uncalibrated.

Direct and separate control of the RF modulator and the attenuator is

possible.

The ALC Off configuration is useful for applications that involve pulse

modulation with extremely narrow pulses. For pulse widths less than

the minimum specified for leveled pulse, the ALC will not maintain

accurate leveling and therefore the ALC off mode must be selected.

For complete specifications, refer to: “Specifications and

Characteristics” on page 6-1.

NOTE Turning on I/Q or IF turns off ALC Leveling. ALC Leveling can be

turned back on manually using the ALC On/Off control.
