Basic Safety Instructions

Operating states and operating positions

The product may be operated only under the operating conditions and in the positions specified by the
manufacturer, without the product's ventilation being obstructed. If the manufacturer's specifications are
not observed, this can result in electric shock, fire and/or serious personal injury or death. Applicable local
or national safety regulations and rules for the prevention of accidents must be observed in all work
performed.

1. Unless otherwise specified, the following requirements apply to Rohde & Schwarz products:
predefined operating position is always with the housing floor facing down, IP protection 2X, use only
indoors, max. operating altitude 2000 m above sea level, max. transport altitude 4500 m above sea
level. A tolerance of ±10 % shall apply to the nominal voltage and ±5 % to the nominal frequency,
overvoltage category 2, pollution degree 2.

2. Do not place the product on surfaces, vehicles, cabinets or tables that for reasons of weight or stability
are unsuitable for this purpose. Always follow the manufacturer's installation instructions when
installing the product and fastening it to objects or structures (e.g. walls and shelves). An installation
that is not carried out as described in the product documentation could result in personal injury or
even death.

3. Do not place the product on heat-generating devices such as radiators or fan heaters. The ambient
temperature must not exceed the maximum temperature specified in the product documentation or in
the data sheet. Product overheating can cause electric shock, fire and/or serious personal injury or
even death.

Electrical safety

If the information on electrical safety is not observed either at all or to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.

1. Prior to switching on the product, always ensure that the nominal voltage setting on the product
matches the nominal voltage of the mains-supply network. If a different voltage is to be set, the power
fuse of the product may have to be changed accordingly.

2. In the case of products of safety class I with movable power cord and connector, operation is
permitted only on sockets with a protective conductor contact and protective conductor.

3. Intentionally breaking the protective conductor either in the feed line or in the product itself is not
permitted. Doing so can result in the danger of an electric shock from the product. If extension cords
or connector strips are implemented, they must be checked on a regular basis to ensure that they are
safe to use.

4. If there is no power switch for disconnecting the product from the mains, or if the power switch is not
suitable for this purpose, use the plug of the connecting cable to disconnect the product from the
mains. In such cases, always ensure that the power plug is easily reachable and accessible at all
times. For example, if the power plug is the disconnecting device, the length of the connecting cable
must not exceed 3 m. Functional or electronic switches are not suitable for providing disconnection
from the AC supply network. If products without power switches are integrated into racks or systems,
the disconnecting device must be provided at the system level.

5. Never use the product if the power cable is damaged. Check the power cables on a regular basis to
ensure that they are in proper operating condition. By taking appropriate safety measures and
carefully laying the power cable, ensure that the cable cannot be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.

1171.0000.42 - 08 Page 3

Basic Safety Instructions

6. The product may be operated only from TN/TT supply networks fuse-protected with max. 16 A (higher
fuse only after consulting with the Rohde & Schwarz group of companies).

7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket provided for this purpose. Otherwise, sparks that result in fire and/or injuries may occur.

8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric
shocks.

9. For measurements in circuits with voltages V

> 30 V, suitable measures (e.g. appropriate

rms

measuring equipment, fuse protection, current limiting, electrical separation, insulation) should be
taken to avoid any hazards.

10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC 60950-1 / EN 60950-1 or IEC 61010-1 / EN 61010-1 standards that
apply in each case.

11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in
operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the
product.

12. If a product is to be permanently installed, the connection between the protective conductor terminal
on site and the product's protective conductor must be made first before any other connection is
made. The product may be installed and connected only by a licensed electrician.

13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective
devices, the supply circuit must be fuse-protected in such a way that anyone who has access to the
product, as well as the product itself, is adequately protected from injury or damage.

14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of
lightning) can reach the product. Otherwise, the person operating the product will be exposed to the
danger of an electric shock.

15. Any object that is not designed to be placed in the openings of the housing must not be used for this
purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.

16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and
operating positions", item 1). Therefore, the equipment must be protected against penetration by
liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product
itself may be damaged, which can also lead to personal injury.

17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.

18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network
or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such
as alcohol, acetone or diluents for cellulose lacquers.

Operation

1. Operating the products requires special training and intense concentration. Make sure that persons
who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries
or material damage may occur. It is the responsibility of the employer/operator to select suitable
personnel for operating the products.

1171.0000.42 - 08 Page 4

Basic Safety Instructions

2. Before you move or transport the product, read and observe the section titled "Transport".

3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a
skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz
product, consult a physician immediately to determine the cause and to prevent health problems or
stress.

4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be
sure to read and pay special attention to the section titled "Waste disposal/Environmental protection",
item 1.

5. Depending on the function, certain products such as RF radio equipment can produce an elevated
level of electromagnetic radiation. Considering that unborn babies require increased protection,
pregnant women must be protected by appropriate measures. Persons with pacemakers may also be
exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take measures to avert the
potential danger.

6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can
cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and
protective clothing must be worn.

7. Laser products are given warning labels that are standardized according to their laser class. Lasers
can cause biological harm due to the properties of their radiation and due to their extremely
concentrated electromagnetic power. If a laser product (e.g. a CD/DVD drive) is integrated into a
Rohde & Schwarz product, absolutely no other settings or functions may be used as described in the
product documentation. The objective is to prevent personal injury (e.g. due to laser beams).

8. EMC classes (in line with EN 55011/CISPR 11, and analogously with EN 55022/CISPR 22,
EN 55032/CISPR 32)

Instrucciones de seguridad elementales

Funcionamiento

1. El uso del producto requiere instrucciones especiales y una alta concentración durante el manejo.
Debe asegurarse que las personas que manejen el producto estén a la altura de los requerimientos
necesarios en cuanto a aptitudes físicas, psíquicas y emocionales, ya que de otra manera no se
pueden excluir lesiones o daños de objetos. El empresario u operador es responsable de seleccionar
el personal usuario apto para el manejo del producto.

2. Antes de desplazar o transportar el producto, lea y tenga en cuenta el capítulo "Transporte".

3. Como con todo producto de fabricación industrial no puede quedar excluida en general la posibilidad
de que se produzcan alergias provocadas por algunos materiales empleados ―los llamados
alérgenos (p. ej. el níquel)―. Si durante el manejo de productos Rohde & Schwarz se producen
reacciones alérgicas, como p. ej. irritaciones cutáneas, estornudos continuos, enrojecimiento de la
conjuntiva o dificultades respiratorias, debe avisarse inmediatamente a un médico para investigar las
causas y evitar cualquier molestia o daño a la salud.

4. Antes de la manipulación mecánica y/o térmica o el desmontaje del producto, debe tenerse en cuenta
imprescindiblemente el capítulo "Eliminación/protección del medio ambiente", punto 1.

5. Ciertos productos, como p. ej. las instalaciones de radiocomunicación RF, pueden a causa de su
función natural, emitir una radiación electromagnética aumentada. Deben tomarse todas las medidas
necesarias para la protección de las mujeres embarazadas. También las personas con marcapasos
pueden correr peligro a causa de la radiación electromagnética. El empresario/operador tiene la
obligación de evaluar y señalizar las áreas de trabajo en las que exista un riesgo elevado de
exposición a radiaciones.

6. Tenga en cuenta que en caso de incendio pueden desprenderse del producto sustancias tóxicas
(gases, líquidos etc.) que pueden generar daños a la salud. Por eso, en caso de incendio deben
usarse medidas adecuadas, como p. ej. máscaras antigás e indumentaria de protección.

7. Los productos con láser están provistos de indicaciones de advertencia normalizadas en función de la
clase de láser del que se trate. Los rayos láser pueden provocar daños de tipo biológico a causa de
las propiedades de su radiación y debido a su concentración extrema de potencia electromagnética.
En caso de que un producto Rohde & Schwarz contenga un producto láser (p. ej. un lector de
CD/DVD), no debe usarse ninguna otra configuración o función aparte de las descritas en la
documentación del producto, a fin de evitar lesiones (p. ej. debidas a irradiación láser).

8. Clases de compatibilidad electromagnética (conforme a EN 55011 / CISPR 11; y en analogía con EN
55022 / CISPR 22, EN 55032 / CISPR 32)
 Aparato de clase A:

Aparato adecuado para su uso en todos los entornos excepto en los residenciales y en aquellos
conectados directamente a una red de distribución de baja tensión que suministra corriente a
edificios residenciales.
Nota: Los aparatos de clase A están destinados al uso en entornos industriales. Estos aparatos
pueden causar perturbaciones radioeléctricas en entornos residenciales debido a posibles
perturbaciones guiadas o radiadas. En este caso, se le podrá solicitar al operador que tome las
medidas adecuadas para eliminar estas perturbaciones.

 Aparato de clase B:

Aparato adecuado para su uso en entornos residenciales, así como en aquellos conectados
directamente a una red de distribución de baja tensión que suministra corriente a edificios
residenciales.

Instrucciones de seguridad elementales

Reparación y mantenimiento

1. El producto solamente debe ser abierto por personal especializado con autorización para ello. Antes
de manipular el producto o abrirlo, es obligatorio desconectarlo de la tensión de alimentación, para
evitar toda posibilidad de choque eléctrico.

2. El ajuste, el cambio de partes, el mantenimiento y la reparación deberán ser efectuadas solamente
por electricistas autorizados por Rohde & Schwarz. Si se reponen partes con importancia para los
aspectos de seguridad (p. ej. el enchufe, los transformadores o los fusibles), solamente podrán ser
sustituidos por partes originales. Después de cada cambio de partes relevantes para la seguridad
deberá realizarse un control de seguridad (control a primera vista, control del conductor de
protección, medición de resistencia de aislamiento, medición de la corriente de fuga, control de
funcionamiento). Con esto queda garantizada la seguridad del producto.

Baterías y acumuladores o celdas

Si no se siguen (o se siguen de modo insuficiente) las indicaciones en cuanto a las baterías y
acumuladores o celdas, pueden producirse explosiones, incendios y/o lesiones graves con posible
consecuencia de muerte. El manejo de baterías y acumuladores con electrolitos alcalinos (p. ej. celdas de
litio) debe seguir el estándar EN 62133.

1. No deben desmontarse, abrirse ni triturarse las celdas.

2. Las celdas o baterías no deben someterse a calor ni fuego. Debe evitarse el almacenamiento a la luz
directa del sol. Las celdas y baterías deben mantenerse limpias y secas. Limpiar las conexiones
sucias con un paño seco y limpio.

3. Las celdas o baterías no deben cortocircuitarse. Es peligroso almacenar las celdas o baterías en
estuches o cajones en cuyo interior puedan cortocircuitarse por contacto recíproco o por contacto con
otros materiales conductores. No deben extraerse las celdas o baterías de sus embalajes originales
hasta el momento en que vayan a utilizarse.

4. Las celdas o baterías no deben someterse a impactos mecánicos fuertes indebidos.

5. En caso de falta de estanqueidad de una celda, el líquido vertido no debe entrar en contacto con la
piel ni los ojos. Si se produce contacto, lavar con agua abundante la zona afectada y avisar a un
médico.

6. En caso de cambio o recarga inadecuados, las celdas o baterías que contienen electrolitos alcalinos
(p. ej. las celdas de litio) pueden explotar. Para garantizar la seguridad del producto, las celdas o
baterías solo deben ser sustituidas por el tipo Rohde & Schwarz correspondiente (ver lista de
recambios).

7. Las baterías y celdas deben reciclarse y no deben tirarse a la basura doméstica. Las baterías o
acumuladores que contienen plomo, mercurio o cadmio deben tratarse como residuos especiales.
Respete en esta relación las normas nacionales de eliminación y reciclaje.

Transporte

1. El producto puede tener un peso elevado. Por eso es necesario desplazarlo o transportarlo con
precaución y, si es necesario, usando un sistema de elevación adecuado (p. ej. una carretilla
elevadora), a fin de evitar lesiones en la espalda u otros daños personales.

1171.0000.42 - 08 Page 13

Instrucciones de seguridad elementales

2. Las asas instaladas en los productos sirven solamente de ayuda para el transporte del producto por
personas. Por eso no está permitido utilizar las asas para la sujeción en o sobre medios de transporte
como p. ej. grúas, carretillas elevadoras de horquilla, carros etc. Es responsabilidad suya fijar los
productos de manera segura a los medios de transporte o elevación. Para evitar daños personales o
daños en el producto, siga las instrucciones de seguridad del fabricante del medio de transporte o
elevación utilizado.

3. Si se utiliza el producto dentro de un vehículo, recae de manera exclusiva en el conductor la
responsabilidad de conducir el vehículo de manera segura y adecuada. El fabricante no asumirá
ninguna responsabilidad por accidentes o colisiones. No utilice nunca el producto dentro de un
vehículo en movimiento si esto pudiera distraer al conductor. Asegure el producto dentro del vehículo
debidamente para evitar, en caso de un accidente, lesiones u otra clase de daños.

Eliminación/protección del medio ambiente

1. Los dispositivos marcados contienen una batería o un acumulador que no se debe desechar con los
residuos domésticos sin clasificar, sino que debe ser recogido por separado. La eliminación se debe
efectuar exclusivamente a través de un punto de recogida apropiado o del servicio de atención al
cliente de Rohde & Schwarz.

2. Los dispositivos eléctricos usados no se deben desechar con los residuos domésticos sin clasificar,
sino que deben ser recogidos por separado.
Rohde & Schwarz GmbH & Co.KG ha elaborado un concepto de eliminación de residuos y asume
plenamente los deberes de recogida y eliminación para los fabricantes dentro de la UE. Para
desechar el producto de manera respetuosa con el medio ambiente, diríjase a su servicio de atención
al cliente de Rohde & Schwarz.

3. Si se trabaja de manera mecánica y/o térmica cualquier producto o componente más allá del
funcionamiento previsto, pueden liberarse sustancias peligrosas (polvos con contenido de metales
pesados como p. ej. plomo, berilio o níquel). Por eso el producto solo debe ser desmontado por
personal especializado con formación adecuada. Un desmontaje inadecuado puede ocasionar daños
para la salud. Se deben tener en cuenta las directivas nacionales referentes a la eliminación de
residuos.

4. En caso de que durante el trato del producto se formen sustancias peligrosas o combustibles que
deban tratarse como residuos especiales (p. ej. refrigerantes o aceites de motor con intervalos de
cambio definidos), deben tenerse en cuenta las indicaciones de seguridad del fabricante de dichas
sustancias y las normas regionales de eliminación de residuos. Tenga en cuenta también en caso
necesario las indicaciones de seguridad especiales contenidas en la documentación del producto. La
eliminación incorrecta de sustancias peligrosas o combustibles puede causar daños a la salud o
daños al medio ambiente.

Power Supply Options

By standard the R&S FSL is equipped with an AC power supply connector. In order to use
the R&S FSL independently from an AC power supply, the R&S FSL can be additionally
fitted with a DC power supply connector (option DC Power Supply, R&S FSL-B30) or a
battery pack (option NiMH Battery Pack, R&S FSL-B31). For details on the connectors refer
to chapter 1 "Front and Rear Panel".

From the available power supplies, the R&S FSL selects the one to use according to the
following priority scheme:

Priority Power supply

1 AC power supply
2 DC power supply
3 battery

For example, if the R&S FSL is connected to both an AC and a DC power supply, it uses the
AC power supply. If it is suddenly disconnected from the AC power supply, it switches to the
DC power supply.

Instrument modes

Three different instrument modes exist:

• On mode

The instrument is supplied with AC power, DC power or battery. After booting, the
instrument is ready for operation. A green LED above the ON/STANDBY key indicates
this mode.

• Standby mode

This mode is only available if the instrument is connected to the AC power supply (AC
power switch in position I; for details refer to chapter 1, "Front and Rear Panel", section
"AC power supply connector and AC power switch"). A yellow LED above the
ON/STANDBY key indicates this mode. Parts of the instrument are still active, e.g. the

oven of the OCXO unit (option OCXO Reference Frequency, R&S FSL-B4) is kept active

or the battery (option NiMH Battery Pack, R&S FSL-B31) will be charged. To prevent the
instrument from overheating, the fan remains active.

When switched on in this mode, the R&S FSL will rapidly resume operation. It preserves
the current settings and when switched back on, the last measurement is displayed.

• Off mode

The instrument is switched off completely. Both LEDs are off. When switched on again,

the instrument starts booting. If the OCXO unit (option OCXO Reference Frequency,

R&S FSL-B4) is used, an extended warm–up phase as specified in the data sheet is
required.

Connecting USB Devices

The two USB interfaces on the front panel of the R&S FSL allow you to connect USB
devices directly to the analyzer. This number can be increased as necessary by using USB
hubs.

Due to the large number of available USB devices, there is almost no limit to the expansions
that are possible with the R&S FSL. The following list shows various USB devices that can
be useful for the R&S FSL:

• Power sensors of the NRP Zxy family

• Memory stick for easy transfer of data to/from a computer (e.g. firmware updates)

• CD–ROM drives for easy installation of firmware applications

• Keyboard for entering comments, file names, etc

• Mouse for easy operation of Windows dialog boxes

• Printer for printing out measurement results

1300.2519.62 2.13 E-10

Connecting External Devices R&S FSL

Installing USB devices is easy under Windows XP, because all USB devices are plug&play.
All USB devices can be connected to or disconnected from the R&S FSL during operation.

After a device is connected to the USB interface of the R&S FSL, Windows XP automatically
searches for a suitable device driver.

If Windows XP does not find a suitable driver, it will prompt you to specify a directory that
contains the driver software. If the driver software is on a CD, connect a USB CD–ROM
drive to the R&S FSL before proceeding.

When a USB device is subsequently disconnected from the R&S FSL, Windows XP
immediately detects the change in hardware configuration and deactivates the
corresponding driver.

Example: To connect a memory stick to the R&S FSL

1. Connect the memory stick to the USB interface.
Windows XP detects the new hardware and installs the corresponding driver. If
installation is successful, Windows XP informs you that the device is ready to use.

The memory stick is made available as a new drive (D:) and is displayed under Windows
Explorer. The name of the memory stick is manufacturer–dependent (in this example it is
called "Removable Disk"). The memory stick can be used like a normal drive to load or
store data.

LXI Configuration R&S FSL

LXI Configuration

LAN eXtensions for Instrumentation (LXI) is an instrumentation platform for measuring
instruments and test systems that is based on standard Ethernet technology. LXI is intended
to be the LAN-based successor to GPIB, combining the advantages of Ethernet with the
simplicity and familiarity of GPIB.

LXI classes and LXI functionality

LXI-compliant instruments are divided into three classes, A, B and C, with the functionality of
the classes hierarchically based one upon the other:

Class A

LXI hardware trigger bus

Class B

IEEE 1588 synchronization

Class C

Ethernet LAN interface
Web server
VXI-11 protocol
IVI instrument driver

• Class C instruments are characterized by a common LAN implementation, including an

ICMP ping responder for diagnostics. The instruments can be configured via a web
browser; a LAN Configuration Initialize (LCI) mechanism resets the LAN configuration.
The LXI class C instruments shall also support automatic detection in a LAN via the VXI­11 discovery protocol and programming by means of IVI drivers.

• Class B adds IEEE 1588 Precision Time Protocol (PTP) and peer-to-peer

communication to the base class. IEEE 1588 allows all instruments on the same network
to automatically synchronize to the most accurate clock available and then provide time
stamps or time-based synchronization signals to all instruments with exceptional
accuracy.

• Class A instruments are additionally equipped with the eight-channel hardware trigger

bus (LVDS interface) defined in the LXI standard.
Instruments of classes A and B can generate and receive software triggers via LAN
messages and communicate with each other without involving the controller.
The R&S ESL complies with LXI class C. In addition to the general class C features
described above, it provides the following LXI-related functionality:

• Integrated LXI Configuration dialog for LXI activation and reset of the LAN configuration

(LAN Configuration Initialize, LCI).

1300.2519.62 2.24 E-10

LXI Configuration R&S FSL

Note: The LXI functionality requires a Windows XP operating system that has been

upgraded to service pack 2. Please contact your Rohde & Schwarz service
representative if your R&S FSL's operating system needs an upgrade. To check
the version of your operating system, open the Versions+Options dialog box in
the General Setup submenu (SETUP key – for details refer to the Operating
Manual, chapter 4: Instrument Functions – Basic Settings).

After a firmware update, use the standby key to shut-down and re-start the

instrument in order to enable the full LXI functionality.

For information about the LXI standard refer to the LXI website at http://www.lxistandard.org.
See also "News from Rohde & Schwarz, article 2006/II - 190".

LXI Configuration Dialog

This dialog provides basic LXI information for the R&S FSL. Press the Info softkey in the
General Setup menu to open the LXI Configuration dialog box (for details refer to the
Operating Manual, chapter 4: Instrument Functions – Basic Settings).

Default state of the network settings

According to the LXI standard, an LCI must place the following parameters to a default
state. For details on resetting the R&S FSL refer to the Operating Manual, chapter 4:
Instrument Functions – Basic Settings.

Parameter Value

TCP/IP Mode DHCP + Auto IP Address
Dynamic DNS Enabled
ICMP Ping Enabled
Password for LAN configuration LxiWebIfc

1300.2519.62 2.25 E-10

LXI Configuration R&S FSL

The LCI for the R&S FSL also resets the following parameters:

Parameter Value

Description R&S Spectrum Analyzer/FSL/<serial number>
Negotiation Auto Detect
VXI-11 Discovery Enabled

The LAN settings are configured using the instrument's LXI Browser Interface.

LXI Browser Interface

The instrument's LXI browser interface works correctly with all W3C compliant browsers.
Typing the instrument's host name or IP address in the address field of the browser on your

PC, e.g. http://10.113.10.203 , opens the Instrument Home Page (welcome page).

The instrument home page displays the device information required by the LXI standard
including the VISA resource string in read-only format.
The LAN Status toggle button causes the LXI logo in the status bar of the R&S FSL to blink
(if active). A green LXI status symbol indicates that a LAN connection has been established;
a red symbol indicates that no LAN cable is connected. The LAN Status setting is not
password-protected.

1300.2519.62 2.26 E-10

LXI Configuration R&S FSL

The navigation pane of the browser interface contains the following control elements:

• LAN Configuration opens the LAN Configuration page.

• LXI Glossary opens a document with a glossary of terms related to the LXI standard.

• Status displays information about the LXI status of the instrument.

LAN Configuration

The LAN Configuration web page displays all mandatory LAN parameters and allows their
modification.

The TCP/IP Mode configuration field controls how the IP address for the instrument gets
assigned (see also <Link to IP Address Settings>). For the manual configuration mode, the
static IP address, subnet mask, and default gateway are used to configure the LAN. The
automatic configuration mode uses DHCP server or Dynamic Link Local Addressing
(Automatic IP) to obtain the instrument IP address.

Note: Changing the LAN configuration is password-protected. The password reads

LxiWebIfc (notice upper and lower case characters).

The links across the bottom of the LAN Configuration page open other pages:

• Ping Client provides the ping utility to verify the connection between the instrument and

other devices.

• Advanced LAN Configuration provides LAN settings that are not declared mandatory by

the LXI standard.

1300.2519.62 2.27 E-10

LXI Configuration R&S FSL

The Advanced LAN Configuration parameters are used as follows:

• The Negotiation configuration field provides different Ethernet speed and duplex mode

settings. In general, the Auto Detect mode is sufficient.

• ICMP Ping must be enabled to use the ping utility.

• VXI-11 is the protocol that is used for discovery of the instrument in the LAN. According

to the standard, LXI devices must use VXI-11 to provide a discovery mechanism; other

additional discovery mechanisms are permitted.

Ping

Ping is a utility that verifies the connection between the LXI-compliant instrument and
another device. The ping command uses the ICMP echo request and echo reply packets to
determine whether the LAN connection is functional. Ping is useful for diagnosing IP
network or router failures.
The ping utility is not password-protected. To initiate a ping between the LXI-compliant
instrument and a second connected device,

1. Enable ICMP Ping on the Advanced LAN Configuration page (enabled after an LCI).

2. Enter the IP address of the second device without the ping command and without any

further parameters into the Destination Address field (e.g. 10.113.10.203).

3. Click Submit.

Setting up the connection does not cause any problems on the network. Likewise,
disconnecting the instrument from the network does not cause any problems as long as no
data traffic to and from the instrument is in progress.

Risk of network errors!

Before connecting the instrument to the network, consult your network
administrator, particularly in the case of large LAN installations.
Connection errors may affect the entire network.

Never connect your analyzer to a network unprotected against virus infection
because this may cause damage to the instrument software.

Configuring the Network Card

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

Changing the IP address and configuring the network protocols (TCP/IP protocol)

Before starting, check the following:

• Which IP addresses and subnet masks are suitable for your network? If necessary, ask

your network administrator.

• Has your network a DHCP server? If necessary, ask your network administrator.

If your network has a DHCP server, the IP address is to be requested from a DHCP

server automatically. For the further proceeding refer to "To configure the network

protocol in a network with DHCP server".

If your network has no DHCP server, refer to "To configure the network protocol in a

network without DHCP server".

R&S FSL Setting Parameters

Setting Parameters

This section describes how to operate the R&S FSL. The instrument provides a user
interface for operation without external keyboard:

• Keypad

• Rotary Knob

• Softkeys

• Dialog Boxes

All tasks necessary to operate the instrument can be performed using this user interface.
Apart from instrument specific keys all other keys that correspond to an external keyboard
(e.g. arrow keys, ENTER key) operate conform to Microsoft. The following basic tasks are
described in this section:

• To enter numeric parameters

• To enter alphanumeric parameters

• To navigate in dialog boxes

• Specialties in Windows dialog boxes

Keypad

The keypad is used to enter alphanumeric parameters. It
contains the following keys:

• Alphanumeric keys

Enters numbers and (special) characters in edit dialog
boxes. For details refer to "To enter numeric parameters"
and "To enter alphanumeric parameters".

• Decimal point

Inserts a decimal point "." at the cursor position.

• Sign key

Changes the sign of a numeric parameter. In the case of an
alphanumeric parameter, inserts a "–" at the cursor position.

• Unit keys (GHz/–dBm MHz/dBm, kHz/dB and Hz/dB)

These keys add the selected unit to the entered numeric value and complete the entry.
In the case of level entries (e.g. in dB) or dimensionless values, all units have the value

"1" as mulitplying factor. Thus, they have the same function as an ENTER key. The
same is true for an alphanumeric entry.

• ESC CANCEL key

Closes all kinds of dialog boxes, if the edit mode is not active. Quits the edit mode, if the
edit mode is active. In dialog boxes that contain a Cancel button it activates that button.

For edit dialog boxes the following mechanism is used:
– If the data entry has been started, it will retain the original value .
– If the data entry has not been started or has been completed, it will close the dialog.

1300.2519.62 4.7 E-10

Setting Parameters R&S FSL

• ENTER key

– Concludes the entry of dimensionless entries. The new value is accepted.
– With other entries, this key can be used instead of the Hz / dB.. unit key.
– In a dialog box, presses the default or focused button.
– In a dialog box, activates the edit mode for the focused area, if available. For details

on the edit mode refer to section "To navigate in dialog boxes".

– In a dialog box, activates or deactivates the selected option of the focused area, if the

edit mode is active.

• BACK key

– If an alphanumeric entry has already been started, this key deletes the character to

the left of the cursor.

– If an entry has been completed or not yet started, this key toggles between the

currently and the previously entered value (undo function).

Rotary Knob

The rotary knob has several functions:

• Increments (clockwise direction) or decrements (counter–

clockwise direction) the instrument parameter at a defined
step width in the case of a numeric entry.

• Moves the focus from one element of the graphical user

interface to another like the FIELD RIGHT and FIELD LEFT
keys.

• Shifts the selection bar within focused areas (e.g. lists), if the

edit mode is activated.

• Shifts markers, limit lines, etc on the screen.

• Acts like the ENTER key, when it is pressed. For details

refer to section "Keypad".

• Moves the scroll bar vertically, if the scroll bar is focused

and the edit mode is activated.
For details on the edit mode refer to section "To navigate in

R&S FSL Setting Parameters

Dialog Boxes

In most cases, the R&S FSL dialog boxes are designed to enter a numeric value. In the
documentation, these dialog boxes are called "edit dialog boxes". Dialog boxes that are not
only designed for parameter entry have a more complex structure and, in the
documentation, are called "dialog boxes". They are described in section "To navigate in
dialog boxes". The navigation in Windows dialog boxes differs in some aspects from the
navigation in R&S FSL dialog boxes. For details refer to "Specialties in Windows dialog
boxes".

The following figure shows an example of a edit dialog box:

Fig. 4-1 Edit dialog box for parameter entry

The title bar shows the name of the parameter that was selected. The entry is performed in
the editing line. When the dialog box is displayed, the focus is on the editing line and it
contains the currently used parameter value and its unit. The optional third line shows status
and error messages which always refer to the current entry.

To enter numeric parameters

If a field requires numeric input, the keypad provides only numbers.

1. Enter the parameter value using the keypad, or change the currently used parameter

value by using the rotary knob (small steps) or the UPARROW or DNARROW keys
(large steps).

2. After entering the numeric value via keypad, press the corresponding unit key.
The unit is added to the entry.

3. If the parameter does not require a unit, confirm the entered value by pressing the
ENTER key or one of the unit keys.
The editing line is highlighted in order to confirm the entry.

To enter alphanumeric parameters

If a field requires alphanumeric input, the keypad provides numbers and (special)
characters. Every alphanumeric key provides several characters and one number. The
decimal point key (.) provides special characters, and the sign key (–) toggles between
capital and small letters. For the assignment refer to Table 4–2. In principle, the input of
alphanumeric parameters works like writing an SMS on your cell phone.

1. To enter the numbers and (special) characters via the keypad:

Measuring a Sinusoidal Signal R&S FSL

Measuring a Sinusoidal Signal

One of the most common measurement tasks that can be handled by using a spectrum
analyzer is determining the level and frequency of a signal. When measuring an unknown
signal, you can usually start with the preset setting.

Note: If levels higher than +30 dBm (=1 W) are expected or are possible, a power

attenuator must be inserted before the RF input of the analyzer. If this is not
done, signal levels exceeding 30 dBm can damage the RF attenuator or the
input mixer. The total power of all signals that are present must be taken into
account.

In the following examples, a signal generator is used as a signal source.

Test setup:

 Connect the RF output of the signal generator to the RF input of R&S FSL.

Signal generator settings (e.g. R&S SMU):

Frequency: 128 MHz
Level: –30 dBm

Measuring the Level and Frequency Using Markers

The level and frequency of a sinusoidal signal can be measured easily by using the marker
function. The R&S FSL always displays its amplitude and frequency at the marker position.
The frequency measurement uncertainty is determined by the frequency reference of the
R&S FSL, the resolution of the marker frequency display and the resolution of the screen.

Procedure:

1. Reset the instrument.

– Press the PRESET key.

2. Connect the signal to be measured to the RF INPUT analyzer input on the instrument
front panel.

3. Set the center frequency to 128 MHz.
– Press the FREQ key.

The dialog box for the center frequency is displayed.

– In the dialog box, enter 128 using the numeric keypad and confirm the entry with the

MHz key.

4. Reduce the frequency span to 1 MHz.
– Press the SPAN key.

– In the dialog box, enter 1 using the numeric keypad and confirm the entry with the

MHz key.

R&S FSL Measuring a Sinusoidal Signal

Note: When the frequency span is defined, the resolution bandwidth, the video

bandwidth and the sweep time are automatically reset, because these functions
are defined as coupled functions in the preset setting.

5. Measure the level and frequency using the marker and read the results from the screen.

– Press the MKR key.

The marker is activated and automatically set on the maximum of the trace.

Note: When a marker is initially activated, it automatically performs the peak search

function (as shown in the example).

If a marker was already active, you have to press the Peak softkey in the

marker–> menu in order to set the currently active marker to the maximum of
the displayed signal.

The level and frequency values measured by the marker are displayed in the marker
field at the top edge of the screen. They can be taken as the measurement result.

M1[1] –30.00 dBm

128.000000000 MHz
The field header indicates the number of the marker (Marker 1) and the trace on which

the marker is located ([1] = Trace 1).

Increasing the Frequency Resolution

The frequency resolution of the marker is predefined by the pixel resolution of the trace. A
trace uses 501 pixels, i.e. when the frequency span is 1 MHz, each pixel corresponds to a
span of approx. 2 kHz. This corresponds to a maximum uncertainty of +/– 1 kHz.
You can increase the pixel resolution of the trace by reducing the frequency span.

 Reduce the frequency span to 10 kHz.

– Press the SPAN key.
– Using the numeric keypad, enter 10 in the dialog box and confirm the entry with the

kHz key.
The generator signal is measured using a span of 10 kHz. The pixel resolution of the

trace is now approx. 20 Hz (10 kHz span / 501 pixels) , i.e. the precision of the

marker frequency display increases to approx. ±10 Hz.

Setting the Reference Level

With spectrum analyzers, the reference level is the level at the upper limit of the diagram. To
achieve the widest dynamic range possible for a spectrum measurement, use the entire
level span of the spectrum analyzer. In other words, the highest level that occurs in the
signal should be located at the top edge of the diagram (=reference level) or immediately
below it.

1300.2519.62 5.3 E-10

Measuring a Sinusoidal Signal R&S FSL

Note: If the reference level that is selected is less than the highest signal that occurs

in the spectrum, the signal path in the R&S FSL will be overloaded.
In this case, the message IFOVL is displayed on the left–hand edge of the
diagram.

In the preset setting, the value of the reference level is –20 dBm. If the input signal is –30 dBm,
the reference level can be reduced by 10 dB without causing the signal path to be overloaded.

1. Reduce the reference level by 10 dB.
– Press the AMPT key.

The amplitude menu is displayed in the softkey bar. The Ref Level softkey is
highlighted in red to indicate that it is activated for data entry. The dialog box for the
reference level is also opened and displays a value of –20 dBm.

– Using the numeric keypad, enter 30 and confirm the entry with the –dBm key.

The reference level is set to –30 dBm. The maximum of the trace is near the
maximum of the measurement diagram. However, the increase in the displayed noise
is not substantial. Thus, the distance between the signal maximum and the noise
display (=dynamic range) has increased.

2. Setting the marker level equal to the reference level
The marker can also be used to shift the maximum value of the trace directly to the top

edge of the diagram. If the marker is located at the maximum level of the trace (as in this
example), the reference level can be moved to the marker level as follows:

– Press the MKR –> key.
– Press the Peak softkey.
– Press the Ref Lvl=Mkr Lvl softkey.

The reference level is set equal to the measured level where the marker is located.

Thus, setting the reference level is reduced to two keystrokes.

Measuring the Signal Frequency Using the Frequency Counter

The built–in frequency counter makes it possible to measure the frequency more accurately
than measuring it with the marker. The frequency sweep is stopped at the marker, and the
R&S FSL measures the frequency of the signal at the marker position.

In the following example, the frequency of the generator at 128 MHz is shown by using the
marker.

1. Set the spectrum analyzer to the default state.
– Press the PRESET key.

The R&S FSL is set to its default state.

R&S FSL Measuring a Sinusoidal Signal

2. Set the center frequency and the span.

– Press the FREQ key and enter 128 MHz.

The center frequency of the R&S FSL is set to 128 MHz.

– Press the SPAN key and enter 1 MHz.

The frequency span of the R&S FSL is set to 1 MHz.

3. Activate the marker

– Press the MKR key.

The marker is activated and set to the signal maximum. The level and the frequency
of the marker are displayed in the marker field.

4. Activate the frequency counter.

– In the marker menu, press the Sig Count On/Off softkey.

The result of frequency counting is displayed in the selected resolution in the marker
field at the top edge of the screen.

Fig. 5–1 Measurement of the frequency with the frequency counter

Note: Obtaining a correct result when measuring the frequency with the internal

frequency counter requires that an RF sinusoidal signal or a spectral line be
present. The marker must be located more than 25 dB above the noise level to
ensure that the specified measurement accuracy is adhered to.
