USB
The front panel provides two female USB connectors to connect devices like a key-
board or mouse. Also a memory stick can be connected to store and reload instrument
settings and measurement data.
NOISE SOURCE CONTROL
The noise source control female connector is used to provide the supply voltage for an
external noise source, e.g., to measure the noise figure and gain of amplifiers and fre-
quency converting DUTs.
Conventional noise sources require a voltage of +28 V in order to be switched on and
0 V to be switched off. The output supports a maximum load of 100 mA.
RF INPUT 50Ω
The RF input is to be connected to the DUT via a cable equipped with an appropriate
connector.
Risk of instrument damage
Do not overload the input. For maximum allowed values, see the data sheet.
For AC-coupling, a DC input voltage of 50 V must never be exceeded. For DC-cou-
pling, DC voltage must not be applied at the input. In both cases, noncompliance will
destroy the input mixers.
PROBE POWER
The R&S FSVA/FSV 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 power supply for high-impedance probes from Agilent.
POWER SENSOR
The LEMOSA female connector is used to connect power sensors of the R&S NRP
family (requires option R&S FSVA/FSV-K9). For details on supported power sensors
see the data sheet.
2.1.1.4 Optional Front Panel Connectors
AF OUTPUT (Audio Demodulator option, R&S FSV-B3)
Headphones equipped with a miniature jack plug can be connected to the AF output
female connector. The internal impedance is 10 Ω. The output voltage can be set by
using the volume control to the right of the female connector. If a plug is connected, the
internal loudspeaker is automatically switched off.

The R&S FSVA/FSV is equipped with an optional tracking generator and therefore pro-
vides a tracking generator output connector.
The output of the tracking generator is to be connected to the DUT via a cable equip-
ped with a male N connector. The female connector is available only with the tracking
generator option (R&S FSV-B9).
If the output is active, the LED is green.
Risk of damaging the tracking generator
To avoid damaging the tracking generator, make sure that the reverse power (i.e. input
power caused, for example, by reflections in the test setup) never exceeds 1 W RF
power. Do not apply a DC voltage at the output.
For details, refer to the data sheet.
Sensitive DUTs concerning matching
For DUTs with sensitive RF characteristics with regard to matching (VSWR) at the
input, insert a 10 dB attenuator between the DUT and the tracking generator.
Connections for External Mixers (EXT MIXER, Option R&S FSV-B21)
External mixers can be connected at the LO OUT/IF IN and IF IN female connectors
(option R&S FSV-B21 for R&S FSVA/FSV 30 and R&S FSVA/FSV 40 instruments).
Both two-port and three-port mixers can be used. Connect the mixer as follows:
Use the supplied coaxial cable to feed in the LO signal. If no external mixers are con-
nected to the R&S FSVA/FSV, cover the two front connectors LO OUT / IF IN and IF
IN with the SMA caps supplied.

Three-port mixer
1. Connect the LO OUT / IF IN output of the R&S FSVA/FSV to the LO port of the
external mixer.
2. Connect the IF IN input of the R&S FSVA/FSV to the IF port of the external mixer.
3. Feed the signal to be measured to the RF input of the external mixer.
Two-port mixer
1. 1. Connect the LO OUT / IF IN output of the R&S FSVA/FSV to the LO/IF port of
the external mixer. The nominal LO level is 15.5 dBm.
Because of the diplexer contained in the R&S FSVA/FSV, the IF signal can be tap-
ped from the line which is used to feed the LO signal to the mixer.

For details refer to Chapter 2.2.1.8, "Switching the Instrument On and Off",
on page 33.
Warm-up time for OCXO
When the instrument is switched on, the OCXO requires an extended warm-up time
(see data sheet).
LAN
The LAN interface can be used to connect the R&S FSVA/FSV to a local network for
remote control, printouts and data transfer. The assignment of the RJ-45 connector
supports twisted-pair category 5 UTP/STP cables in a star configuration (UTP stands
for unshielded twisted pair, and STP for shielded twisted pair).
MONITOR (VGA)
The female VGA connector is used to connect an external monitor. Step-by-step
instructions how to connect an external monitor are provided in Chapter 2.2.3, "Con-
necting an External Monitor", on page 36.
EXT TRIGGER / GATE IN
The female connector for external trigger/gate input is used to control the measure-
ment by means of an external signal. The voltage levels can range from 0.5 to 3.5 V.
The default value is 1.4 V. The typical input impedance is 10 kΩ.
REF IN
As a reference signal, you can either use the internal reference, or connect an external
one. The setup menu is used to switch between the internal and an external reference.
The REF IN female connector is used as an input for a 1-20 MHz reference signal. The
required input level is 0-10 dBm.
REF OUT
This connector can be used to provide an external reference signal (e.g. the OCXO or
ultra high precision reference signal) to other devices that are connected to this instru-
ment. The REF OUT female connector can output a 10 MHz reference signal with an
output level of 0 dBm.
GPIB interface
The GPIB interface is in compliance with IEEE488 and SCPI. A computer for remote
control can be connected via this interface. To set up the connection, a shielded cable
is recommended. For more details refer to chapter 7 "Remote Control Basics" in the
Operating Manual.
