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)

1171.0000.42 - 08 Page 5

Basic Safety Instructions

2. Adjustments, replacement of parts, maintenance and repair may be performed only by electrical
experts authorized by Rohde & Schwarz. Only original parts may be used for replacing parts relevant
to safety (e.g. power switches, power transformers, fuses). A safety test must always be performed
after parts relevant to safety have been replaced (visual inspection, protective conductor test,
insulation resistance measurement, leakage current measurement, functional test). This helps ensure
the continued safety of the product.

Batteries and rechargeable batteries/cells

If the information regarding batteries and rechargeable batteries/cells is not observed either at all or to the
extent necessary, product users may be exposed to the risk of explosions, fire and/or serious personal
injury, and, in some cases, death. Batteries and rechargeable batteries with alkaline electrolytes (e.g.
lithium cells) must be handled in accordance with the EN 62133 standard.

1. Cells must not be taken apart or crushed.

2. Cells or batteries must not be exposed to heat or fire. Storage in direct sunlight must be avoided.
Keep cells and batteries clean and dry. Clean soiled connectors using a dry, clean cloth.

3. Cells or batteries must not be short-circuited. Cells or batteries must not be stored in a box or in a
drawer where they can short-circuit each other, or where they can be short-circuited by other
conductive materials. Cells and batteries must not be removed from their original packaging until they
are ready to be used.

4. Cells and batteries must not be exposed to any mechanical shocks that are stronger than permitted.

5. If a cell develops a leak, the fluid must not be allowed to come into contact with the skin or eyes. If
contact occurs, wash the affected area with plenty of water and seek medical aid.

6. Improperly replacing or charging cells or batteries that contain alkaline electrolytes (e.g. lithium cells)
can cause explosions. Replace cells or batteries only with the matching Rohde & Schwarz type (see
parts list) in order to ensure the safety of the product.

7. Cells and batteries must be recycled and kept separate from residual waste. Rechargeable batteries
and normal batteries that contain lead, mercury or cadmium are hazardous waste. Observe the
national regulations regarding waste disposal and recycling.

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.

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.

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

The fuses are accommodated in the fuse holders next to the power connector. Use
only fuses of the mentioned type.

Shock hazard

Before replacing a fuse, make sure that the instrument 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.

2.4 Connecting External Accessories

The equivalent USB ports on the front and/or rear panel of the R&S SMA can be used
to connect a variety of accessories.

In addition the instrument provides interfaces for network integration (see Chapter 2.6,

"Setting Up a Network (LAN) Connection", on page 36).

2.4.1 Connecting USB Devices

Via the USB ports, you can connect external devices directly to the R&S SMA. If you
need more interfaces, you just use an USB hub.

33Operating Manual 1400.0075.32 ─ 14

R&S®SMA100A

Preparing for Use

Linux Operating System

The following list shows various USB devices that can be useful:

●

Memory stick for easy transfer of data to/from a computer (for example firmware
updates)

●

CD-ROM drives for easy installation of firmware applications

●

Keyboard or mouse to simplify the entry of data, comments, file names, etc.

●

Power sensors, for example of the NRP Zxy family

Installing USB devices is easy under Linux, because all USB devices are plug&play.
After a device is connected to the USB interface, the operating system automatically
searches for a suitable device driver.

If Linux 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 instrument before proceeding.

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

All USB devices can be connected to or disconnected from the instrument during oper­ation.

Connecting a memory stick or CD-ROM drive

If installation of a memory stick or CD-ROM drive is successful, the operating system
informs you that the device is ready to use. The device is made available as a new
drive (/usb). The name of the drive is manufacturer-dependent.

Connecting a keyboard

The keyboard is detected automatically when it is connected. The default keyboard lay­out is English – US.

Use the "Setup > Keyboard Settings" dialog to configure the keyboard properties.

Connecting a mouse

The mouse is detected automatically when it is connected.

2.5 Linux Operating System

The instrument uses an embedded Linux operating system. To make sure that the
instrument software works properly, certain rules must be adhered to concerning the
operating system.

34Operating Manual 1400.0075.32 ─ 14

R&S®SMA100A

Preparing for Use

Linux Operating System

Risk of causing instrument unusability

The instrument is equipped with the Linux 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 Linux have been adapted to
the instrument. Existing instrument software must always be modified using only
update software released by Rohde & Schwarz.

The configuration of the operating system is optimally adapted to signal generator
functions in the factory. Changes in the system setup are only required when peripher­als like keyboard are installed or if the network configuration does not comply with the
default settings (see Chapter 2.6.1, "Connecting the Instrument to the Network",
on page 36). After the R&S SMA is started, the operating system boots and the
instrument firmware is started automatically.

Accessing Operating System

No access to the operating system is required for normal operation.

All necessary system settings can be made in the "Setup" dialog.

The R&S SMA provides a internal CompactFlashTM Card, it does not contain a disk
drive. The CompactFlashTM Card holds the firmware and the stored data. However,

data transfer is only possible via a memory stick connected to a USB interface. The
memory stick and the CompactFlashTM Card are accessed via the "File Manager".

Accessing the File System

The instrument also supports two standard methods to access the file system form a
remote client:

●

FTP (file transfer protocol)

●

File sharing according to the SAMBA/SMB (server message block) protocol.

Both methods allow the access to the folder /var/user/share.

Default password

The FTP and SAMBA/SMB file access use the user "instrument" with the default pass­word "instrument".

It is highly recommenced that you change this password in the Chapter 5.2.3.19,

"Security", on page 117 dialog before connecting the instrument to the network!

Refer also to Application Note 1GP72 "Connectivity of Signal Generators", provided on
the Rohde & Schwarz website, at http://www.rohde-schwarz.com/appnotes.

Preparing for Use

Setting Up a Network (LAN) Connection

Screen saver

A screen saver can be activated in the R&S SMA. When active, the display is shut off
when no entries via front panel, external mouse or external keyboard are made for a
period of time. The screen saver prolongs the life time of the display.

Use the "Setup > Display Settings" dialog to switch on or off the screen saver and to
adjust the screen saver settings.

2.6 Setting Up a Network (LAN) Connection

The R&S SMA is equipped with a network interface and can be connected to an Ether­net LAN (local area network). Provided the appropriate rights have been assigned by
the network administrator and the Linux firewall configuration is adapted accordingly,
the interface can be used, for example:

●

To transfer data between a controller and the instrument, e.g. in order to run a
remote control program.
See Chapter 6, "Remote Control Basics", on page 347.

●

To access or control the measurement from a remote computer using the R&S
VISA or Ultr@VNC programs (or similar tools, like another VNC client or any Web
browser supporting Java)

●

To transfer data from a remote computer and back, e.g. using network folders

This section describes how to configure the LAN interface. It includes the following top­ics:

●

Chapter 2.6.1, "Connecting the Instrument to the Network", on page 36

●

Chapter 2.6.2, "Assigning the IP Address", on page 37

Accessing Operating System

No access to the operating system is required for normal operation.

All necessary system settings can be made in the "Setup" dialog.

2.6.1 Connecting the Instrument to the Network

There are two methods to establish a LAN connection to the instrument:

●

A non-dedicated network (Ethernet) connection from the instrument to an existing
network

●

A dedicated network connection (Point-to-point connection) between the instru­ment and a single computer

In both cases, an IP address has to be assigned to the instrument and the computer,
which is usually accomplished automatically. See also Chapter 2.6.2, "Assigning the IP

Address", on page 37.

R&S®SMA100A

Preparing for Use

Setting Up a Network (LAN) Connection

To set up a network (LAN) connection

Risk of network failure

Before connecting the instrument to the network or configuring the network, consult
your network administrator. Errors may affect the entire network.

► Connect the instrument to the network or to a single PC.

If the instrument is connected to the LAN, the operating system automatically
detects the network connection and activates the required drivers.
By default, the instrument is configured to use dynamic TCP/IP configuration and
obtain all address information automatically.

The network card can be operated with a 10 Mbps Ethernet IEEE 802.3 or a 100 Mbps
Ethernet IEEE 802.3u interface.

Risk of network connection failure

Network cables and cable connectors of poor quality may cause network connection
failures.

If the network connection to the instrument fails, check the network infrastructure and
contact your network administrator.

For details, see section "Status Information, Error Messages and Troubleshooting".

2.6.2 Assigning the IP Address

Depending on the network capacities, the TCP/IP address information for the instru­ment can be obtained in different ways.

●

If the network supports dynamic TCP/IP configuration using the Dynamic Host
Configuration Protocol (DHCP), all address information can be assigned automati­cally.

●

If the network does not support DHCP, the instrument tries to obtain the IP address
via Zeroconf (APIPA) protocol. If this attempt does not succeed or if the instrument
is set to use alternate TCP/IP configuration, the addresses must be set manually.

By default, the instrument is configured to use dynamic TCP/IP configuration and
obtain all address information automatically. This means that it is safe to establish a
physical connection to the LAN without any previous instrument configuration.

37Operating Manual 1400.0075.32 ─ 14

R&S®SMA100A

Preparing for Use

Setting Up a Network (LAN) Connection

Risk of network errors!

Connection errors can affect the entire network.

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 instru­ment to the LAN.

Contact your network administrator to obtain a valid IP address.

Assigning the IP address on the instrument

1. Press the SETUP key and select the "Network Settings" dialog.

2. Set the "Address Mode" to Static.

3. Select the "IP Address" and enter the IP address, for example 192.168.0.1..

The IP address consists of four number blocks separated by dots. Every block con­tains 3 numbers in maximum.

4. Select the "Subnet Mask" and enter the subnet mask, for example 255.255.255.0.

The subnet mask consists of four number blocks separated by dots. Every block
contains 3 numbers in maximum.

Use computer names to identify the instrument

In networks using a DHCP server, it is recommended that you address the instrument
by its unambiguous computer name, see Chapter 2.6.3, "Using Computer Names",
on page 38.

A computer name (hostname) is an unique dedicated identification of the instrument,
that remains permanent as long as it is not explicitly changed. Hence, you can address
an instrument by the same identification (computer name), irrespectively if a network or
a point-to-point connection is used.

To assign the IP address manually on the remote computer

► Obtain the necessary information from your network administrator. If you use more

than one LAN connector, you need separate address information for each connec­tor.
For information on how to perform the configurations, refer to the documentation of
the operating system the remote computer uses.

2.6.3 Using Computer Names

In a LAN that uses a DNS server (Domain Name System server), each PC or instru­ment connected in the LAN can be accessed via an unambiguous computer name
instead of the IP address. The DNS server translates the host name to the IP address.
This is especially useful when a DHCP server is used, as a new IP address may be
assigned each time the instrument is restarted.

38Operating Manual 1400.0075.32 ─ 14

R&S®SMA100A

Preparing for Use

Remote Access via an External Controller

Each instrument is delivered with an assigned computer name, but this name can be
changed.

The default instrument name is a non-case-sensitive string that follows the syntax
rs<instrument><serial number>.

The serial number can be found on the rear panel of the instrument. It is the third part
of the device ID printed on the bar code sticker:

Querying and changing a computer name

1. Press the "Setup" key and select "Network Settings".

The computer name is displayed under "Hostname".

2. Press the "Setup" key, select "Protection" and enable the "Protection Level 1".

The default password is 123456.

configuration.

3. Change the "Hostname".

2.7 Remote Access via an External Controller

The R&S SMA can be remote accessed from a remote computer (external controller)
via a network link. This allows convenient operation of the instrument from the desktop
although the instrument is integrated in a rack somewhere else.

For an overview of the instrument's operating concept and the different ways to control
and operate the instrument, see Chapter 3.1, "Brief Introduction to the Instrument's

Concept", on page 56.

There are different ways to establish a remote access connection to the signal genera­tor but all of them require an established LAN connection between the instrument and
the remote computer. The simplest way to remote access the instrument is to use a
Web browser, such as Windows Internet Explorer or Mozilla Firefox for instance. Alter­natively a remote access via a special application can be used.

For example, the free-of-charge program Ultr@VNC for PCs with Linux/Unix or Win­dows operating system is available for setting up the remote access connection. Using
this application requires additional installation.

See the following table for an overview of the different ways to establish a remote
access connection to the signal generator.

2.8 LXI Configuration

LXI ("LAN eXtensions for Instrumentation" 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.

Like GPIB, LXI determines and standardizes the way the instrument behaves in a LAN.
The LXI implementation by the Rohde&Schwarz signal generators allows you to
change certain LAN settings, to reset the LAN connection as well as to identify the
instrument easily.

Brief Introduction to the Instrument's Concept

This section helps you to get familiar with the R&S SMA. It provides an introduction to
the general concept of the instrument with a sample of the possible application fields,
and a description of the main blocks in the signal generation flow.

This section also explains the operating concept in general and includes a brief intro­duction to operation by a step-by-step description of the configuration. The example is
intended to provide a quick overview of the settings provided. No additional equipment
is required.

3.1 Brief Introduction to the Instrument's Concept

The operating concept of the R&S SMA employs the following three ways of instru­ment control:

●

Manual operation

●

Remote control

●

Remote access

Manual Operation

The R&S SMA can be entirely operated from the front panel. Peripherals such as
mouse or keyboard can be connected but are not essential.

The R&S SMA is equipped with an intuitive user interface. The central element of the
display is the block diagram that shows the signal flow and processing from the left on
the display to most right, i.e. the generated signal can be seen at a glance.

Each block represents a functional unit of the instrument. Thus you always know the
position at which a parameter affects the signal flow. The main settings of a block are
indicated in the block. The interconnection of employed inputs and outputs is also
shown. The user is thus always informed about the connection of inputs and outputs in
the signal flow and where they can be configured. A window is opened for each menu
where parameters can be set. When the window is opened, an entry is made in the
"Winbar" below the display. All open menus are of equal priority (not modal) and can
be accessed any time.

The block diagram in the figure below shows a fully equipped instrument.

Getting Started

Brief Introduction to the Instrument's Concept

Figure 3-1: Block diagram of a fully equipped R&S SMA

With the rotary knob, you can navigate in the block diagram and the dialogs, and oper­ate the instrument with one hand. The cursor is moved line by line through the block
diagram or dialog. Turning the button clockwise advances the cursor. The selected
block can be activated or deactivated with the TOGGLE key. Active blocks are high­lighted by a colored background.

The instrument comprises a comprehensive info and help system. You can access the
context-sensitive help with the HELP (F1) key at any time. The help system indicates
the currently selected parameter and offers additional services such as cross referen­ces, index and contents. The content of the help system corresponds to the operating
manual of the instrument.

Warning and conflict messages caused by incorrect operation as well as further infor­mation are displayed in the "Info" line. A complete list of existing conflicts is displayed
when the INFO (CTRL+I) key is pressed. Additional information on entries can be
requested from the help system. The history function permits display of all messages.

Assistants simplify the completion of tables. After data entry in the assistant, the table
is modified only after the "Accept" button has been pressed. Pressing the "Accept" but­ton also stores the assistant data.

For an introduction into the manual operating of the instrument, detailed operating
instructions and an overview of menus refer to Chapter 4, "Manual Operation",
on page 67.

For an in-depth description of the dialog boxes and the instrument functions, refer to
section Chapter 5.1, "Overview of Instrument Functions", on page 92.

Remote Control

Remote control is an operation of the instrument by means of remote control com­mands or programs that automatize repeating settings. The instrument is connected to
a computer running the program.

The R&S SMA supports various remote control connections:

●

Connecting the instrument to a (LAN) network

●

Using the LXI browser interface in a LAN network

●

Connecting a PC via the IEC-bus (IEEE 488) interface

●

Remote control via the USB interface

Description of Individual Diagram Blocks

Tip: For remote control over LAN or USB, you can use the R&S VISA (Virtual Instru-
ment Software Architecture) library provided for download at the Rohde & Schwarz
website http://www.rohde-schwarz.com/rsvisa.

This way of operation and the instructions how to set up a connection for remote con­trol are described in the Chapter 6, "Remote Control Basics", on page 347. The
description of the remote control commands is provided in Chapter 7, "Remote Control

Commands", on page 391.

Remote access

Remote access is the operating of the instrument from a remote computer. Both the
R&S SMA and the computer are connected in a LAN.

Remote access in contrast to remote control does not use remote-control commands
but a separate software which is installed on the remote computer. After its start, the
software simulates the user interface of the instrument. The instrument can thus be
operated from the remote computer as on the unit itself. The individual functions are
operated using the mouse and keyboard. Specific instrument functions can be execu­ted using specific key combinations on the keyboard or a front panel key emulation that
can be operated with the mouse.

This way of operation and the instructions how to set up a connection for remote
access are described in Chapter 2.7, "Remote Access via an External Controller",
on page 39.

3.2 Application Field of the Instrument

The main field of application of the R&S SMA is the generation of sine wave signals
with very high spectral purity. These signals are needed for example for adjacent chan­nel or phase noise measurements.

In addition, the RF signal can be modulated with a wide variety of internal modulations
waveforms, like sine waves, triangle/rectangular/trapeze signals, and noise. Several
modulation signals can be combined with variable weight.

3.3 Description of Individual Diagram Blocks

The signal path of the instrument is configured by installing a frequency option that
comprises all required modules including synthesizer, output section and attenuator
(optional without attenuator).

Manual Operation

Key Features

The R&S SMA can be operated intuitively either via the interactive block diagram or via
a menu tree. All menus are in the form of windows that can be operated in the same
way. Rotary knob, keys and softkeys, or alternatively a mouse, allow direct and there­fore convenient access to entries and settings.

The clear-cut display shows the current signal generator state. Numerous help func­tions support the user in signal configuration.

This section describes the concept of manual operation of the signal generator. This
includes a description of the general structure of a dialog box, working with dialog
boxes and the block diagram and the setting of parameters.

For an in-depth description of the dialog boxes and the instrument functions refer to
section "Instrument Functions".

4.1 Key Features

The manual operating concept of the R&S SMA enables the user to make settings as
intuitively as possible and at the same time gives a permanent overview of characteris­tics of the generated signal and of the current instrument state. Numerous online help
functions support user settings.

Block diagram

The block diagram is the core of the operating concept.

A graphics display shows the current configuration and the signal flow in the form of a
block diagram. All graphical elements can be accessed for operation. An element is
selected by means of the arrow keys and the associated setting function is called by
pressing Enter. Required menus and graphs are displayed on the block diagram which
is displayed again in the foreground whenever the DIAGRAM (CTRL+D) key is
pressed.

Permanent frequency and level display

The main characteristics of the RF signal, frequency and level, are permanently dis­played in the header section of the screen and can be directly set in the display fields
after the FREQ (CTRL+F) or LEVEL (CTRL+L) key is pressed. Status messages for
the output signal are displayed in addition to frequency and level.

Operation via Graphical User Interface

●

Functional blocks

Menus are assigned to the specific function blocks in the block diagram. The func­tion blocks represent elements of signal generation. Function blocks displayed with

67Operating Manual 1400.0075.32 ─ 14

R&S®SMA100A

Manual Operation

Key Features

a blue frame can be directly switched on and off by means of the TOGGLE
ON/OFF (CTRL+T) key. The menus of the highlighted function blocks can be
called by pressing the ENTER key.

– Example:

The "Modulation" block contains all menus required for modulation signal con-

figuration.

In this block all modulations can be selected.

●

Signal flow

The signal flow between the function blocks and the employed inputs and outputs
are also shown.

●

Menu tree

The menu tree can be opened and closed with the MENU (CTRL+M) key. The
menu tree is organized in the same way as the directories under Windows. The
function blocks correspond to the first directory level, the menus to subdirectories.

Operation corresponds to the Windows concept

To offer the user a familiar environment, operation is very similar to operation of Win­dows user interfaces. All menus and tables are made up of known elements, such as
selection lists, check boxes and entry fields.

A blue frame indicates that the selected item is active. In the highlighted element,
entries can be made.

Rotary knob

Operation is possible via front-panel keys, an external keyboard and the mouse. How­ever, most of the settings can be easily made with the rotary knob:

●

Turning the rotary knob shifts the entry focus to the target element.

68Operating Manual 1400.0075.32 ─ 14

R&S®SMA100A

Manual Operation

Key Features

●

Pressing the rotary knob activates the selected entry field.
Depending on the parameter, the submenu is called, the numeric value varied, the
list entry selected or the check box activated or deactivated.

●

If a value is entered, the entry is stored by another click on the rotary knob and the
editing mode is exited.

Clear settings with the aid of independent subdialogs

A separate window is opened for each dialog and subdialog. The dialogs can be oper­ated independently of each other, i.e. none of the dialogs requires that settings in other
dialogs be completed before it can be closed. This ensures flexible operation at all
times.

Keys with assigned simple functions

Most keys on the front panel of the R&S SMA directly perform a simple function.

Since a great number of settings can thus be made by a keystroke, operation is easy.
For instance, the CLOSE (ESC) key closes the active menu; with the RF ON/OFF
(CTRL+R) key the RF output signal can be switched on or off.

An exception are keys that call a menu such as the MENU (CTRL+M) key which opens
the complete menu tree of the instrument, the SETUP (CTRL+E) key which opens the
menus for general instrument settings or the FILE (CTRL+S) key which opens the
menu for file management.

Help functions for user support

Numerous help functions support the user in signal configuration.

●

Value ranges

The valid setting range is displayed for each numeric parameter. This requires a
short wait after activation of the entry field. The range is then displayed automati­cally after a few seconds.

If the entered value is outside the permissible range, the next permissible value is
automatically set and a message is output.

●

Context-sensitive help

Context-sensitive help for each parameter can be called with the HELP or F1 key.

●

Comprehensive online help

Each help page is part of a comprehensive online help function which can be
called by means of an index, a content tree or the "Previous/Next" buttons.

Info line with messages for indication of the current instrument state

A great variety of different messages such as status messages, error messages, warn­ings or information are displayed in the header field of the screen. With the aid of the
INFO (CTRL+I) key, help pages can be called for most of the messages. They provide

background information on the message and indicate operating steps that may be
required. All messages are explained in the online help which can be called with the
HELP (F1) key.

4.2 Display

The display shows the current signal generator state and offers graphical elements for
direct operation. It is divided into three sections:

●

The frequency and level display with info line indicates the main output signal
parameters and reports the current state with status, error and warning messages.

●

The block diagram shows the instrument configuration, the signal characteristic as
well as the inputs and outputs used and permits interactive operation via graphics
elements. Active menus and graphs are displayed on top of the block diagram.

●

Winbar with labeled softkeys for menu display.

The block diagram in the figure below shows a fully equipped instrument.

4.2.2 Status Information and Messages

The instrument indicates status information and messages in the header section of the
screen. The messages differ with respect to their importance (errors, warnings, info)
and the time of their appearance (brief and permanent messages), and require differ­ent treatment

For additional information refer to the info window (see Chapter 4.2.3, "Info Window",
on page 72).

Refer to Chapter 9, "Status Information, Error Messages and Troubleshooting",
on page 688 for an overview of all status information and messages and corrective
actions.

4.2.2.1 Status Information

The status information gives the user an overview of the main operating states and set­tings of the instrument. The states are indicated for information only and do not neces­sitate any action by the user.

Status information is displayed between the frequency and level fields, at the left of the
info line or in the info line itself.

4.2.2.2 Messages

Messages indicate errors in the instrument. They are displayed in the info line in differ­ent colors depending on their importance and display duration. Errors (e.g. no calibra­tion data) are displayed in red, information (e.g. file not found) and warnings in black.
Warnings indicate less significant errors (e.g. the instrument operates outside specified
data).

4.2.2.3 Volatile messages

Brief messages report automatic settings in the instrument (e.g. switching off of incom­patible types of modulation) or on illegal entries that are not accepted by the instrument
(e.g. range violations). They are displayed in the info line on a yellow background.
They are displayed on top of status information or permanent messages.

Volatile messages do not normally demand user actions and disappear automatically
after a brief period of time. They are stored in the history, however.

These messages can be read from remote using the commands :SYSTem:ERRor[:

NEXT]? and :SYSTem:ERRor:ALL?.

4.2.2.4 Permanent Messages

Permanent messages are displayed if an error occurs that impairs further instrument
operation, e.g. a hardware fault. The error signalled by a permanent message must be
eliminated before correct instrument operation can be ensured.

The message is displayed until the error is eliminated. It covers the status display in
the info line. After error elimination, the message automatically disappears and is also
recorded in the history.

These messages can be read from remote using the command :SYSTem:SERRor?.

4.2.3 Info Window

A few operating states and the current message are displayed in the info line.

The INFO window with a list of current permanent messages and a detailed description
of each message can be opened with the INFO (CTRL+I) key.

The upper section of the info window contains a list of all current permanent messages
in the order of their occurrence, i.e. the most recent message is displayed first. In the
lower section of the window, additional information on the highlighted message is dis­played. A history of all messages that have occurred since instrument switch-on can be
called with the "History" key. The most recent message is displayed first.

The messages are color-coded according to their level. Device-specific messages are
red, info and remote control error are black. The level is also indicated in the "Lev"

confirmation. Not yet confirmed settings are displayed on a yellow background as an
indication that the currently displayed values do not represent the target signal.

► To confirm these settings, select the "Save" or "Accept" button, respectively.

Confirming parameters with On/Off state

Most of the instrument functions with enabled and disabled states are calculated and
effective only after this functions have been enabled. However, there are functions like
the frequency variation of the reference oscillator for instance, that are immediately set
after confirmation.

► To confirm a parameter with On/Off state, enable the parameter.

4.4.8 Restoring the Previous Value

Parameter variations with the rotary knob are immediately set and therefore not rever­sible.

Normally, values cannot be restored in the case of mouse control because no explicit
confirmation is required in this case and entries are automatically confirmed when the
entry or selection field is exited.

4.5 Editors

The R&S SMA provides user-friendly editors for defining lists. Lists containing fre­quency and level value pairs are used for the list mode and the user-defined level cor­rection.

The lists are saved to files and may thus have any length. The file name of the lists and
the directory to which the files are saved are user-selectable. The file prefix is different
for each list type and is permanently assigned by the system.

Creating a new list mode data list

A new list can be created under a new name either by generating a blank file in the
"File Select" menu (see section Chapter 4.7, "File Management", on page 85) or by
changing an existing list which will then be saved under a new name.

1. To create an empty data list, select "RF > List Mode > List Mode Data... > New
List" or respectively "RF > User Correction > User Cor. Data... > New User Correc­tion Data" and enter the file name of the new data list.

4.7 File Management

The R&S SMA uses files to save all instrument data, i.e. system and user data.

The user data includes saved instrument settings and lists and the user correction.

The files are stored on the CompactFlashTM card of the instrument. The /var directory
can be used to save user-defined data; any subdirectory structure can be created on /
var. Some default subdirectories are predefined, but can be changed at any time.

The /opt directory is a protected system drive and therefore unaccessible system
directory. The files on this directory contain data that must not be changed. Therefore,
this drive should not be accessed, since reconstruction of the system partition will lead
to data loss. To prevent inadvertent deletion or overwriting of system files, this drive is
not specified in the file menus.

Files can be exchanged either via a memory stick or a connected network. A memory
stick is connected to the USB interface and is assigned the var/usb/ drive. In the
case of a connected network, all network drives that can be accessed are available.
The files are accessed in a "Save/Recall" dialog in the individual menus.

The files are differentiated according to their extensions; each type of file is assigned a
specific file content. The extension is usually of no consequence to the user since
access to the files occurs in the individual menus where only the relevant type of file is
available. See Chapter 4.7.2.1, "Extensions for User Files", on page 88 for an over­view of the supported file extensions.

The user data can be roughly divided into the following data types:

●

Settings
Instrument settings can be saved and loaded. In case of saveing, the current set­ting is saved to the specified file.

●

Lists
