Example:
POW:ALC OFF
Deactivates automatic level control at the RF output.
POW:ALC:OMOD SHOL
Activates the level control briefly when changing the frequency
or level.
[:SOURce<hw>]:POWer:ALC:SEARch <Search>
Recalculates the instrument internal settings optimized for the current level. Not
required for automatic modes.
Parameters:
<Search> ON
*RST: ON
Example:
POW:ALC:SEAR ON
Executes readjustment.
[:SOURce<hw>]:POWer:ALC:SLEVel
<SampLevel>
Sets the sample level of automatic level control (ALC).
NOTICE: Risk of DUT damage due to high input power
If you generate signals with large headroom using POW:ALC:SLEV FULL in combina-
tion with POW:ALC:STAT OFF or POW:ALC:STAT ONS, the R&S SMW generates a
short sample pulse with full RF output power.
To protect the DUT from damage due to high input power, use the setting
POW:ALC:SLEV ATT or POW:ALC:SLEV MIN.
Parameters:
<SampLevel> FULL | MINimum | ATTenuated
*RST: FULL
Example:
POW:ALC:SLEV MIN
Sets the automatic level control to minimum.
Manual operation: See "Sample Level" on page 528
[:SOURce<hw>]:POWer:ALC:SONCe
Activates level control for correction purposes temporarily.
Example:
POW:ALC OFF
Deactivates automatic level control at the RF output.
POW:ALC:SONC
Executes level control (once).
Usage: Event
