The [UNDO] function is not available after a [PRESET] or "RECALL" opera-
tion. When these functions are used, the history of previous actions is
deleted.

RF Input (50
Ω
)
The RF Input allows you to connect a device under test (or DUT) to the
R&S
FSWP, usually via cable and an appropriate connector (for example a male
N connector).
The supported frequency range depends on the R&S
FSWP model you have.
Refer to the datasheet for details.
The RF Input also serves as an attenuator in case you are measuring signal with
high levels. The supported attenuation range depends on the R&S
FSWP model
you have. Refer to the datasheet for details..
Risk of instrument damage
Do not overload the RF input. For maximum allowed values, see the data
sheet.
When measuring unknown signals, always apply attenuation to protect the
input mixer. Otherwise, the input mixer may be damaged or destroyed.
For AC coupling, a DC input voltage of 50
V must never be exceeded. For
DC coupling, DC voltage must not be applied at the input. In both cases,
noncompliance will destroy the input mixers.
4.1.8
Signal Source Output
The optional "Signal Source" output allows you to generate a signal that can be
fed into the DUT or other external accessories like frequency dividers or amplifi-
ers. You can connect the DUT or accessories with a cable that has a male N con-
nector.
