4 Input/Output Functions
Input/Output
Key Path
Input/Output, RF Input
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.
State Saved Saved in instrument state
Readback 50 Ω or 75 Ω . Current setting reads back to the RF key.
Initial S/W Revision Prior to A.02.00
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.

Input/Output, RF Input
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
Backwards
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
