Sets and queries the ALC leveling source selection switch.
The
*RST
value is
INTernal.
l
POWer:ALC[:STATe]
ONlOFFlllO
l
POWer : ALC
[
:
STATe]
?
Sets and queries the state switch of the ALC. The positions are :
ON-normal ALC operation
OFF-open loop ALC mode
When on, the power can be programmed in fundamental units as
selected by the UNIT:POWer command.
When off, the power is no longer calibrated in absolute units and is
set in units of
dB
of arbitrary modulator setting.
l
POWer:AMPLifier:STATE
ONlOFFlOll
l
POWer:AMPLifier:STATE?
Sets and queries the state of the amplifier contained in
the doubler (for those models with a doubler installed).
Programming a specific value for POWer : AMPLif ier : STATE sets
POWer:AMPLifier:STATE:AUTOto OFF.
l
POWer:AMPLifier:STATE:AUTO
ONlOFFlOll
l
POWer:AMPLifier:STATE:AUTO?
Sets and queries the automatic selection of the doubler amplifier
state. Programming a specific value for POWer : AMPLif ier : STATE sets
POWer : AMPLif ier : STATE:AUTO to OFF. *RST value is ON.
l
POWer:ATTenuation
<num>[DB]
lMAXimumlMINimumlUPlDOWN
l
POWer:ATTenuation?
[MAXimumlMINimuml
Sets and queries the output attenuation level. Note that when
setting the attenuator level to 10
dB,
the output power is
decreased by 10
dB.
Programming a specified attenuation sets
POWer:ATTenuation:AUTO OFF.
l
POWer:ATTenuation:AUTO
ONlOFFlllO
l
POWer:ATTenuation:AUTO?
Sets and queries the state of the RF attenuator coupling switch.
Programming a specified attenuation sets
POWer:ATTenuation:AUTO OFF.
ON
-
insures that the amplitude level of the ALC is kept within
optimal limits.
OFF
-
the attenuator setting is set to the value of POW: ATT and left
there. The *RST value is ON.
l POWer:CENTer

l
POWer:CENTer?
[MAXimumlMINimuml
Sets and queries the center power for power sweep. Default units
(and units for query response) are determined by the UNIT:POWer
command.
