COMMAND SUMMARY
Power Subsystem
Any place where
dBm
is accepted as a suffix, any level suffix is
accepted also. In the absence of a suffix, the units are assumed to be
as
set bytheUNIT:POW
command.

POWer:ALC:BANDwidth?l:BWIDth?
[MAXimumlMINimuml
Sets and queries the ALC bandwidth. This is actually not
continuously variable, so the input is rounded to the nearest possible
switch position. *RST setting is automatically determined since AUTO
is
ON.
l
POWer:ALC:BANDwidthl:BWIDth:AUTO
ONlOFFlllO
l
POWer:ALC:BANDwidthl:BWIDth:AUTO?
Sets and queries the automatic ALC bandwidth selection switch. The
*RST value is ON.

l
POWer:ALC:CFACtor?
[MINimumlMAXimuml
Sets and queries the coupling factor used when the command
POWer:ALC[:SOUFke]
is set to
DIODe
or
PMETer.
l
POWer:ALC:SOUFke
INTernallDIODelPMETerlMMHead
l
POWer:ALC:SOUFke?
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:AMPLifier: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
