Subsystem INPut, OUTPut, CORRection:LOSS ( /Ext. Att.)
The subsystem for input and output contains the commands for configuration of the input and output
connectors. The subsystem corresponds to the tab RF in the popup menu Connect. Control.

RF2 – V1.15
Command description
This command determines the connector to be used for incoming RF signals.
The bidirectional connectors RF 1 and RF 2 can be used both as input and output connectors in the same meas-
urement (see OUTPut[:STATe]). Only one input and one output may be active at a time, which is why the cur-
rently active one is automatically deactivated on switchover.

Command description
This command determines the connector to be used for outgoing RF signals.
The bidirectional connectors RF 1 and RF 2 can be used both as input and output connectors in the same meas-
urement. Only one input and one output may be active at a time, which is why the currently active one is auto-
matically deactivated.
