[:SOURce<hw>]:POWer:ALC[:STATe] <State>
Activates automatic level control in the selected mode.
Note: The ALC states POW:ALC:STAT OFF and POW:ALC:STAT ONS use a short
sample pulse to set the level control. The level of this sample pulse corresponds to the
sample level setting of the full PEP of the R&S SMW. It does not consider any signal
headroom, e.g. applied to a user-defined ARB waveform.
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:
<State> AUTO | OFFTable | ON | 1 | OFF | 0 | ONSample | ONTable
AUTO
Adjusts the output level to the operating conditions automati-
cally.
OFFTable
Controls the level with the attenuation values of the internal ALC
table.
ON
Activates internal level control permanently.
OFF
Deactivates internal level control, "Sample & Hold" mode is
active.
ONSample
Starts the internal level control with the first change.
ONTable
Starts with the attenuation setting from the table and continues
with automatic level control.
*RST:
AUTO
Example:
POW:ALC ON
Activates internal level control.
Manual operation: See "State" on page 527
[:SOURce<hw>]:POWer:ATTenuation <Attenuation>
