Defines a source power or a power offset relative to the channel power (SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate][:AMPlitude]) for a frequency converter port <Pt>. The command is available for converters with electronic attenuators (R&S ZVA-ZxxxE). An additional Cal Power Offset can be defined via SOURce<Ch>:POWer<Pt>:CORRection:LEVel:OFFSet.
<Ch>
Channel number
<Pt>
Converter port number
<offset>
Port-specific power offset
Range [def. unit]
–300 dB to +300 dB [dB]. UP and DOWN increment/decrement the phase in 1-dB steps.
*RST value
0 dB
Offset parameters
ONLY – only the port-specific power is used; the channel power is ignored.
CPADd – the port-specific power is added as an offset to the channel power.
CPADd
SCPI, Command Types
Device-specific, command or query
Example:
See SOURce<Ch>:FREQuency<Pt>:CONVersion:ARBitrary:CFRequency
Enables or disables the advanced power transfer model for the converter port <Pt>.
This command is overwritten by the general power transfer model settings; see [SENSe<Ch>:]CONVerter:AMODel.
Channel number.
<Boolean>
ON | OFF - Enables or disables the advanced model.
OFF
SOUR:POW2:CONV:TRAN:AMOD ON; DESC LAPP
Enable the advanced power transfer model at the frequency converter port 2 and select a linear approximation.
SOUR:POW2:CONV:TRAN:SLOP 1; OFFS 0
Define the slope and offset for the linear model with0 dB waveguide attenuators setting.
SOUR:POW2:CONV:TRAN:ATT MECH SOUR:POW2:CONV:TRAN:MECH:ATT 3
Select a converter type with a mechanical waveguide attenuator and define a 3-dB attenuation
Alternatively....
SOUR:POW2:CONV:TRAN:ATT ELEC SOUR:POW2:CONV:TRAN:ELEC:LIM -5; RED 50; MATT 20
Select a converter type with electronic attenuators and define a power threshold of -5 dBm, 50 % power reduction due to the waveguide attenuator, and a maximum attenuation of 20 dB.
Selects the waveguide attenuator type of the converter port <Pt>.
Parameters
MECHanical - Adjustment screw (most converter models R&S ZVA-Zxxx) ELECtronic - Electronic attenuator (converters R&S ZVA.ZxxxE)
MECH
See SOURce<Ch>:POWer<Pt>:CONVerter:TRANsfer:AMODel
Selects the type of advanced power transfer model for the converter port <Pt>.
This command is overwritten by the general power transfer model settings; see [SENSe<Ch>:]CONVerter:DESCription.
