SOURce<Ch>:POWer<Pt>:CONVerter:TRANsfer:DESCription NONE | ELECtronic |
LAPProx | DSET
Selects the power control method for the converter port <Pt>, see Port<i> Power Control.
Since FW version 3.40 this is a global setting.
<Ch>
Channel number. This suffix is ignored, the command affects all channels.
<Pt>
Converter port number
Parameters
NONE - None or Mechanical Attenuator, i.e. no active power control.
Note that this is not compatible with true differential mode or defined coherence
mode: these modes are (temporarily) disabled while power control is inactive.
ELECtronic - Electronic Attenuator only (converters R&S ZVA-ZxxxE only)
LAPProx - RF IN power (and Electronic Attenuator) with Linear Approximation
DSET - RF IN power (and Electronic Attenuator) with Data Set
*RST value
n/a (a *RST does not affect the general frequency converter settings)

Command
Types
Device-specific, command or query
Example:
SOUR:POW2:CONV:TRAN:DESC LAPP
Enable the RF IN power (and Electronic Attenuator) with Linear Approximation
control method at 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.
SOURce<Ch>:POWer<Pt>:CONVerter:TRANsfer:DSET FACTory | USER
For the RF IN power (and Electronic Attenuator) with Data Set control method
(SOURce<Ch>:POWer<Pt>:CONVerter:TRANsfer:DESCription DSET) this command specifies
whether factory data or a user-defined data set shall be used (Data Set mode in Port<i> Power Control
dialog).
This is a global setting.
<Ch>
Channel number. This suffix is ignored, the command affects all channels.
<Pt>
Converter port number
