The [Redo] key repeats the previously reverted action, i.e. the most recent
action is repeated.
The [Undo] function is not available after a [Preset] or "Recall" operation.
When these functions are used, the history of previous actions is deleted.

Trigger Input / Output
Use the female Trigger 1 Input/Output connector to input an external trigger or
gate data. Thus, you can control the measurement using an external signal. The
voltage levels can range from 0.5
V to 3.5
V. The default value is 1.4
V. The typi-
cal Input impedance is 10
kΩ.
The rear panel provides two more Trigger Input / Output connectors, see
Chapter 5.2.7, "Trigger 2/3 In/Out"
5.1.9
RF Input 50 Ohm
Provides RF input from a connected device under test (DUT) to the R&S
FSV/A,
which is then analyzed in an RF measurement. Connect the DUT to the "RF
Input" connector on the R&S
FSV/A. 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 cur-
rent (DC). AC coupling blocks any DC voltage from the input signal. This is the
default setting to prevent damage to the instrument. However, some specifica-
tions require DC coupling. In this case, you must protect the instrument from
damaging DC input voltages manually. For details, refer to the data sheet. For
details on coupling, see the chapter on radio frequency input in the R&S
FSV/A
user manual.

Probe
The R&S
FSV/A provides a connector for supply voltages of +15
V to -12
V and
ground for active probes and preamplifiers. A maximum current of 140
mA is
