The cursor keys move a scroll bar (vertical or horizontal) in dialog boxes that have
one.
Undo and redo functionality
Reverts the software to an older state by erasing the last change you have applied.
The undo function is useful, for example, if you are performing a measurement with
several markers and a limit line and accidentally select a different measurement. In
this case, a lot of settings would be lost. However, if you press [UNDO] immediately
afterwards, the previous status is retrieved.
Reverses an undo action or repeats the most recently performed action.
The [UNDO] function is not available after a [PRESET] or "RECALL" operation. When
these functions are used, the history of previous actions is deleted.

RF Input 50 Ohm
Provides RF input from a connected device under test (DUT) to the R&S
FSPN, which
is then analyzed in an RF measurement. Connect the DUT to the "RF Input" connector
on the R&S
FSPN. Do not overload the input. For maximum allowed values, see the
data sheet.
The RF input can be coupled to the DUT by alternating current (AC) or direct current
(DC). AC coupling blocks any DC voltage from the input signal. This is the default set-
ting to prevent damage to the instrument. However, some specifications require DC
coupling. In this case, you must protect the instrument from damaging DC input vol-
tages manually. For details, refer to the data sheet. For details on coupling, see the
chapter on radio frequency input in the R&S
FSPN user manual.

USB Ports
The three USB ports on the front panel (type A) allow you to connect devices like key-
boards, mouses or memory sticks.
The R&S
FSPN provides additional USB ports (including one type B port) on the rear
panel.
All USB ports support standard 2.0.

Power Sensors
The female Lemosa connector allows you to connect power sensors of the R&S
NRP-
Zxy family to the R&S
FSPN.
For an extensive list of supported power sensors, refer to the data sheet.
