RFIO2
Specifies using the RFIO 2 port, if supported, for the current measurement
RF Calibrator
Lets you choose a calibrator signal to look at or turns the calibrator "off".
Example: :FEED:RF:PORT RFIO1
Dependencies: Only available in EXT.
If Multiport Adapter is ON, Select RF Input to RFIO1, an error message is
generated: “–221, Settings conflict; RFIO1 or RFIO2 Port unavailable when
Multiport Adapter is ON”.

Initial S/W Revision: A.05.01
Key Path:
Input/Output
Remote Command: [:SENSe]:FEED:AREFerence REF50|REF4800|OFF
[:SENSe]:FEED:AREFerence?
Example: FEED:AREF REF50 selects the 50 MHz amplitude reference as the signal
input.
FEED:AREF REF4800 selects the 4.8 GHz amplitude reference as the signal
input
FEED:AREF OFF turns the calibrator "off" (switches back to the selected
input – RF or I/Q)
Dependencies: Selecting an input (RF or I/Q) turns the Calibrator OFF. This is true whether
the input is selected by the keys or with the [:SENSe]:FEED command.
The 4.8 GHz internal reference is only available in some models and
frequency range options. If the 4.8 GHz reference is not present, the
4.8 GHz
softkey will be blanked, and if the REF4800 parameter is sent, the test set will
generate an error.
