Leveling Mode

Normal

Function Group ALC

Menu Map 1

Description This softkey lets you set the leveling mode of the synthesizer to continuous leveling at the desired leveling point. In this mode, the RF OUTPUT is controlled by the automatic level control (ALC) circuit, otherwise referred to as the leveling loop. The attenuator works in conjunction with the ALC to achieve the full range of power levels. At factory preset, ALC normal is the default state. An asterisk next to the key label indicates that this feature is active.

Programming Codes SCPI: POWer:ALC:STATe ONI1

Analyzer: Al, internal normal; A2, external normal; A3, external power meter normal; SHA2, source module normal.

Function Group ALC

Menu Map 1

Description This softkey causes the ALC to switch off once the desired power level is reached. When this leveling mode is activated, or when power, or frequency is changed, the synthesizer switches to CW frequency and closes the ALC system until the desired power level is reached. The synthesizer reverts to its original frequency/modulation state and opens the ALC system. This mode is similar to ALC off mode and is useful for narrow pulse applications. An asterisk next to the key label indicates that this feature is active.
