l 

 ion : 

Queries the status of any modulation. If any of the modulation states

are on, then it returns a 1, otherwise it returns a 0.

Any place where 

 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 by the UNIT :POW command.

l 

POWer:ALC:BANDwidthl:BWIDth 

l 

POWer:ALC:BANDwidth?|:BWIDth? 

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 

is ON.

l 

 

l 

POWer:ALC:BANDwidth|:BWIDth:AUTO?

Sets and queries the automatic ALC bandwidth selection switch. The

 value is ON.

l 

POWer:ALC:CFACtor 

l 

POWer:ALC:CFACtor? 

Sets and queries the coupling factor used when the command

POWer : ALC   

 is set to 

 or 

l 

 

l 

POWer:ALC:SOURce?

Sets and queries the ALC leveling source selection switch.

The *RST value is 

l 

 

l 

POWer : ALC   : 

 ?

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 

 of arbitrary modulator setting.

l 

POWer:AMPLifier:STATE 

l 

POWer : 

 ier : STATE?

Sets and queries the state of the amplifier contained in

the doubler (for those models with a doubler installed).
