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.
3.3.1.8
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 typical Input impe-
dance is 10
kΩ.
The rear panel provides two more Trigger Input / Output connectors, see
ter 3.3.2.7, "Trigger 2/3 in/out"
3.3.1.9
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 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
FSV/A user manual.

3.3.1.10
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 available. This
connector is suitable as a power supply for high-impedance probes.
For details on configuring and using power sensors, see
3.3.1.11
Ext mixer connector (optional)
Connect external mixers to the Ext Mixer IF In and LO Out / IF In female connectors to
increase the available frequency range. These connectors are optional and only availa-
ble with R&S
FSV3-B21.
