Connecting the R&S SFU

Connecting to the AC Power Supply

4 Connecting the R&S SFU

This chapter describes how to connect the R&S SFU to the power supply and external
devices.

4.1 Preventing Electromagnetic Interference

To prevent electromagnetic interference, the R&S SFU must be operated with all
shielding covers fitted. Only suitable and shielded signal and control cables may be
used.

RF/ASI/BER/TRIGGER inputs and outputs

In particular cables that are connected to these inputs/outputs can cause EMC prob­lems. Therefore these cables should have at least 80 dB to 1 GHz shielding. This is
usually achieved by means of double-shielded cables.

TS GEN SER OUT

If a cable is attached to this output, it must be provided with a matched load. For
details on the interface see Chapter 3.2.14, "TS GEN SER OUT", on page 29.

USB interfaces

To connect the USB interfaces, only use peripheral equipment that does not cause
limit violations. For details see Chapter 3.1.12, "USB Interfaces", on page 18.

DIG I/Q IN/OUT

If the DIG I/Q IN/OUT is connected by means of a conventional cable, it is possible that
the specifications of limit class B are not longer met. For details on the interface see

Chapter 3.2.9, "DIG I/Q", on page 24.

LAN interface (100 BASE-T)

To connect the LAN interface (100 BASE-T), use a suitable cable. For details see

Chapter 3.2.7, "100 BASE-T", on page 23.

4.2 Connecting to the AC Power Supply

The R&S SFU can be used with different AC power voltages and adapts itself automat­ically to it. Adjusting the R&S SFU to a particular AC supply voltage is therefore not
required. Refer to the data sheet for the requirements of voltage and frequency.

R&S®SFU

Operating the R&S SFU in a LAN

Connecting the R&S SFU to the Network

7 Operating the R&S SFU in a LAN

The R&S SFU is equipped with a network interface and can be connected to an Ether­net LAN (local area network). The network card operates with 100 MBit Ethernet IEEE

802.3u. The TCP/IP network protocol and the associated network services are precon-

figured.

To be able to exchange data within a local area network (LAN), every computer or
instrument that is connected must have a unique IP address or a unique computer
name. Access between different users is managed with access authorizations.

Provided the appropriate rights have been assigned and the Window XP firewall con­figuration is adapted accordingly, the interface can be used e.g. for transferring data,
printing on network printers, operating the R&S SFU from a remote computer.

To use network resources, access must be granted. To share files on the R&S SFU
with other network users, access to instrument resources, e.g. the hard drives, must
also be granted. All these administration tasks are normally performed by a network
administrator using the Windows XP Start menu (for details refer to the Windows XP
help system). Contact your network administrator for access authorizations.

User name and password of the R&S SFU are factory-set. The user name is used for
auto login, access authorization and remote operation.

For further information:

●

See Chapter 8.1.1, "Login", on page 48

●

See Chapter 3.2.7, "100 BASE-T", on page 23

●

See the user manual or help system for details on remote operation.

7.1 Connecting the R&S SFU to the Network

Risk of network failure/virus infection

Before connecting the R&S SFU to the network or configuring the network, do the fol­lowing:

●

Consult your network administrator.

●

If your network does not support DHCP or if you choose to disable dynamic TCP/IP
configuration, you must assign valid address information before connecting the
R&S SFU to the LAN.

Errors may affect the entire network.

Efficient virus protection is a prerequisite for secure operation in the network. Never
connect the R&S SFU to a network without proper protection against a virus infection,
as doing so may cause damage to the instrument software.

Operating the R&S SFU in a LAN

Configuring the Network Card

To connect the R&S SFU to the network

1. Fulfill all prerequisites mentioned above.

2. Make sure that the R&S SFU is switched off. This is the only way to ensure that the
network connection is reliably detected and any disruptions during the operation of
the R&S SFU are avoided.

3. Connect the R&S SFU to the network using a CAT-5 RJ-45 cable.

4. Switch on the R&S SFU.

To disconnect the R&S SFU from the network

1. Make sure that the R&S SFU is switched off.

2. Disconnect the R&S SFU from the network.

7.2 Establishing a Point-to-Point Connection

To set up a single network (a LAN connection between an R&S SFU and a single com­puter without integration into a larger network), an IP address needs to be assigned to
the R&S SFU and the computer. The IP addresses 192.168.xxx.yyy are available for
use here. xxx and yyy can assume values of 1 to 254, and the value for the subnet
mask is 255.255.255.0.

► Connect the R&S SFU and the computer with a standard RJ-45 cross-over cable.

7.3 Configuring the Network Card

Under Windows XP, network card drivers do not need to be installed separately. If the
R&S SFU is connected to the LAN, Windows XP automatically detects the network
connection and activates the required drivers.

The configuration tasks depend on whether your network has a DHCP server or not. If
necessary, ask your network administrator.

Networks with DHCP Server

The R&S SFU is preconfigured for networks using the dynamic host configuration pro­tocol (DHCP). In such networks, the instrument is automatically assigned a free IP
address. Identification in the network is based on the use of a unique computer name.

Every instrument is assigned an individual computer name at the factory. It is displayed
as part of the window title of the application.

If necessary, you can change the computer name using the firmware or the Win­dows XP Start menu (for details refer to the Windows XP help system).

Querying the computer name using the firmware

1. If the R&S SFU has a default computer name, the computer name is displayed as
part of the window title of the application.

2. If no default computer name is displayed, do the following.

a) Press the SETUP key.
b) In the tree, select "COMMUNICATION".
c) Read out the computer name from the "FULL COMPUTER NAME" field.

Networks without DHCP Server

In networks that assign fixed IP addresses, the network administrator usually config­ures the network card. Contact your network administrator. The IP address is set using
the firmware or the Windows XP Start menu (for details refer to the Windows XP help
system).

Entering the IP address using the firmware

1. Press the SETUP key.

2. In the tree, select "COMMUNICATION".

3. Enter the IP address in the "TCP/IP ADDRESS" field.

7.4 Firewall Settings

By default, the Windows Firewall is activated to protect the R&S SFU from an attack of
hostile users and programs. The Windows Firewall suppresses all network communi­cation which is not initialized by the R&S SFU itself or which is not defined as an
exception.

To enable data transfer or to allow access to the R&S SFU, define exceptions using
the Windows XP Start menu. For details refer to the Windows XP help system or con­tact your network administrator for support.

Operating System

8.1 Operating System

The R&S SFU is equipped with the Windows XP Embedded operating system. When
the R&S SFU is delivered, the operating system is configured for optimum operation.
Changes to the system settings are required only if you install peripherals such as a
keyboard and printer or if you configure the network and the settings do not conform to
the default settings.

Risk of causing instrument unusability

To prevent malfunctions and to avoid instrument repair, only install service packs
approved by Rohde & Schwarz.

In particular, do not use service packs for Windows XP Home Edition or Professional
Edition.

8.1.1 Login

Windows XP requires that you identify yourself by entering a user name and password
in a login window. The R&S SFU provides a factory–installed auto login function, i.e.
login is carried out automatically in the background. The ID used for auto login has
administrator rights.

As user name and password, instrument are factory-set.

If the R&S SFU is connected to a network and if the user name and the password are
identical under Windows XP and on the network, you log on to operating system and
the network at the same time.

8.2 Additional Software

Risk of causing instrument unusability

The instrument is equipped with the Windows XP operating system. Additional soft­ware can therefore be installed on the instrument. The use and installation of additional
software may impair instrument function. Thus, run only programs that Rohde &
Schwarz has tested for compatibility with the instrument software.

The drivers and programs used on the instrument under Windows XP have been adap­ted to the instrument. Existing instrument software must always be modified using only
update software released by Rohde & Schwarz.

8.3 Windows XP Recovery and Backup Partition

The R&S SFU provides a backup and recovery partition. A backup of the factory sys­tem partition (C:\) is stored per default and can be recovered in case of a system
crash.

In addition, backups of up to 5 firmware versions can be stored on this partition. For
example, it is possible to backup the current system partition prior to a firmware update
or to provide different system configurations for different environments. When recov­ered, the system partition (C:/) is deleted, formatted and written newly. The data parti­tion (D:\) is not affected.

Maintenance

Cleaning the Instrument

9 Maintenance

The R&S SFU does not need a periodic maintenance unless it is operated in dusty
areas.

Risk of instrument damage

If the R&S SFU is operated in dusty areas, the fans may become obstructed by dust or
other particles in the process of time. Make sure to check and, if necessary, clean the
fans regularly to ensure they operate properly at all times. If the R&S SFU is run with
obstructed fans for a longer period, it may become overheated which may cause dam­age.

Clean the outside of the instrument when necessary and check the rated data from
time to time.

If any problem arises, contact one of our customer support centers. The addresses of
our customer support centers are provided at the beginning of this manual.

9.1 Cleaning the Instrument

Shock hazard

Before cleaning the R&S SFU, make sure that the R&S SFU is switched off and dis­connected from all power supplies.

1. Clean the outside of the R&S SFU using a soft, lint-free dust cloth.

2. Make sure that vents are not obstructed.

Instrument damage caused by cleaning agents

Cleaning agents contain substances that may damage the R&S SFU, e.g. cleaning
agents that contain a solvent may damage the front panel labeling or plastic parts.

Never use cleaning agents such as solvents (thinners, acetone, etc), acids, bases, or
other substances.

Maintenance

Storing the Instrument

9.2 Replacing the Fuses

The R&S SFU is protected by two fuses (F1/F2: IEC127-T4.0H/250 V) located on the
rear panel next to the AC power switch.

Shock hazard

Before replacing a fuse, make sure that the R&S SFU is switched off and disconnected
from all power supplies.

Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of the same
type and rating.

To replace the fuses

1. Open the lid of the AC power connector.

2. Lift the fuse holder out of its slot.

3. Exchange the two fuses.

4. Put the fuse holder back in its slot and close the lid.

9.3 Storing the Instrument

The storage temperature range of the R&S SFU is given in the data sheet. If the
R&S SFU is to be stored for a longer period of time, it must be protected against dust.

Repack the R&S SFU as it was originally packed when transporting or shipping. The
two protective foam plastic parts prevent the control elements and connectors from
being damaged. The antistatic packing foil avoids any undesired electrostatic charging
to occur.

If you do not use the original packaging, provide for sufficient padding to prevent the
R&S SFU from slipping inside the package. Wrap antistatic packing foil around the
R&S SFU to protect it from electrostatic charging.
