Subsystem for Input and Output (Connectors, External Attenuation)
The subsystem for input and output configures the input and output connectors. The subsystem corre-
sponds to the tab
RF in the popup menu Connect. Control .

RF4 Connector RF 1 used as input
Connector RF 2 used as input
Connector RF 4 IN used as input RF2 – V1.15
Description of command
This command determines the connector to be used for RF input signals. The bidirectional connectors RF 1 and
RF 2 can be used both as input and output connectors in the same measurement (see
OUTPut[:STATe]
).
Only one input and one output may be active at the same time, a new RF input setting supersedes the previous
one.

Description of command
This command determines the connector to be used for RF output signals. The bidirectional connectors RF 1 and
RF 2 can be used as input and output connectors in the same measurement (see
INPut[:STATe]
).
Only one input and one output may be active at the same time, a new RF output setting supersedes the previous
one.
