SMBV100B
869User Manual 1178.4460.02 ─ 03
Example:
POW:ALC OFF
Deactivates automatic level control at the RF output.
POW:ALC:SONC
Executes level control (once).
Usage: Event
Manual operation: See "Readjust" on page 296
[: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 SMBV100B gener-
ates 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 381
[:SOURce<hw>]:POWer:ATTenuation:DIGital <AttDigital>
Sets a relative attenuation value for the baseband signal.
Parameters:
<AttDigital> float
Range: -3.522 to 80
Increment: 1E-3
*RST: 0
Manual operation: See "Digital Attenuation" on page 294
[:SOURce<hw>]:POWer:ATTenuation:RFOFf:MODE <Mode>
Selects the state the attenuator is to assume if the RF signal is switched off.
Parameters:
<Mode> UNCHanged | FATTenuation
FATTenuation
The attenuator switches to maximum attenuation
