Remote Command
[:SENSe]:CORRection:IMPedance[:INPut][:MAGNitude] 50|75
[:SENSe]:CORRection:IMPedance[:INPut][:MAGNitude]?
Example
CORR:IMP 75 sets the input impedance correction to 75 ohms.
CORR:IMP?
Preset
This is unaffected by a Preset but is set to 50 ohms on a "Restore Input/Output Defaults" or "Restore
System Defaults->All"
Some instruments/options may have 75 ohms available.

RF Input Port
Specifies the RF input port used. The RF Input Port key only appears on units with multiple inputs, and lets
you switch between the two inputs.
Switching from the RF input port to one of the RFIO ports, on units that have them, changes the receiver
performance of the instrument.

Remote Command
[:SENSe]:FEED:RF:PORT[:INPut] RFIN | RFIN2 | RFIO1 | RFIO2 | RFIO3 |
RFIO4
[:SENSe]:FEED:RF:PORT[:INPut]?
Example
:FEED:RF:PORT RFIN
Dependencies
This key only appears in models that support multiple inputs. If the SCPI command is sent with
unsupported parameters in any other model, an error is generated, –221.1900, “Settings
conflict;option not installed”
When any input is selected in a measurement that does not support it, the "No result; Meas invalid
with this input" error condition occurs, and the measurement returns invalid data when queried.
Preset
This is unaffected by Mode Preset but is set to RF on a "Restore Input/Output Defaults" or "Restore
System Defaults -> All"
State Saved
Saved in instrument state
Readback
The current RF Input Port selected is read back to this key

Compatibility SCPI
INPut<1|2>:TYPE INPUT1 | INPUT2
INPut<1|2>:TYPE?
Included for R&S ESU compatibility. In the MXE, the INPUT1 parameter is aliased to RFIN and the
INPUT2 parameter is aliased to RFIN2
