POWer Subsystem [SOURce]
:POWer
[:LEVel] C:IMMediatel C:AMPLitude]?
Returns the value of the current CW amplitude. The return value is in
units of DBM if POWer:REFerence:STATe is OFF, or it is in DB, relative
to the current value of POWer:REFerence if POWer:REFerence:STATe
is ON.
[:LEVel] [:IMMediate] [:AMPLitude] []
Sets CW amplitude. *RST value is -136 dBm.
:ATTenuation
:AUTO?
:AUTO ON I OFF I 1 IO
When set ON, the firmware will control the attenuators. Turning it
OFF causes the attenuator range to hold to it’s present setting.
*RST value is ON.
:REFerence?
:REFerence CNRf> []
Sets a reference value which, if STATe is ON, allows all amplitude
parameters to be queried/set as relative to the reference value.
*RST value is 0 dBm.
:STATe?
:STATe ON 1 OFF I 1 IO
Determines whether amplitude is output in absolute or relative mode.
*RST value is OFF.
PULM Subsystem PULM
:STATe?
:STATe ON 1 OFF 1 1 IO
2-38 HP-IB Programming
This function controls the state of the pulse modulation.
*RST value is OFF
