Power Subsystem

•MODulat ion : STATe?

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 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 by the UNIT :POW command.

•POWer:ALC:BANDwidthl:BWIDth <num>[freq suffix]lMAXimumlMINimum

•POWer:ALC:BANDwidth?: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 AUT( is ON.

•POWer:ALC:BANDwidthl:BWIDth:AUTO ONlOFFlllO

•POWer:ALC:BANDwidth:BWIDth:AUTO?

Sets and queries the automatic ALC bandwidth selection switch. The “RST value is ON.

•POWer:ALC:CFACtor <num>CDB1lMAXimumlMINimumlUPlDOWN

•POWer:ALC:CFACtor? [MINimumlMAXimuml

Sets and queries the coupling factor used when the command POWer : ALC [: SOUFke] is set to DIODe or PMETer.

•POWer:ALC:SOUHce INTernallDIODelPMETerlMMHead

•POWer:ALC:SOURce?

Sets and queries the ALC leveling source selection switch. The *RST value is INTernal.

•POWer:ALC[:STATe] ONlOFFlllO

•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.

•POWer:AMPLifier:STATE ONlOFFlOll

•POWer : AMPLif ier : STATE?

Sets and queries the state of the amplifier contained in the doubler (for those models with a doubler installed).
