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.

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
Page 16
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.

A selftest is provided for service purposes. The selftest is a protected test procedure, which can be accessed if protection level 1 is disabled.
2.3.5.4 Default Settings
When the instrument is switched on, it is not the preset state that is active, but rather
the instrument state that was set before the instrument was switched off. It is also recomended that you use the PRESET key to return the instrument to its defined preset
state every time a new configuration is required or the current setup is not anymore relevant.
The R&S AMU offers a three-stage preset concept:
●
Preset of the settings belonging to a digital standard or associated with one dialog.
Most of the dialog boxes provide a special "Set to Default" button that resets
directly the settings associated to the corresponding dialog, e.g. all digital modulation settings in the "Custom Digital Mod" dialog.
These settings are identical to those which are called up using the PRESET key.
●
Preset the instrument to a predefined state
The PRESET key calls up a defined instrument setup. All parameters and switching states are preset (also those of inactive operating modes). The default instrument settings provide a reproducible initial basis for all other settings. However,
functions that concern the integration of the instrument into a measurement setup
are not changed, e.g. GPIB bus address or reference oscillator source settings.
In remote control it is possible to preset the settings of the two instrument's paths
separately (see section "Preset Commands").
●
Preset the instrument to its factory settings
The instrument can also be forced to load its default factory settings. To access the
corresponding dialog box, press the SETUP key and select the "Factory Preset".
For more information and an overview of the settings affected by the factory preset
function, see section "Factory Preset" in the Operating Manual.
Overview of the Most Important Preset States
The following list gives an overview of the presets for the most important generator settings. The other presets can be found in the preset tables of the individual menus and

2.4.1 Connecting USB Devices
The USB interfaces of the R&S AMU allow you to connect USB devices directly to the
instrument. 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 AMU.
The following list shows various USB devices that can be useful:
●
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 or mouse to simplify the entry of data, comments, file names, etc.
●
Printer for printing out measurement results
●
Power sensors, e.g. of the NRP Zxy family
Installing USB devices is easy under Windows, 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 Windows 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 AMU, Windows
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, Windows informs you
that the device is ready to use. The device is made available as a new drive and is displayed in Windows Explorer. The name of the drive depends on the manufacturer.
Connecting a keyboard
The keyboard is detected automatically when it is connected. The default input language is English – US.
Select "Start > Control Panel > Clock, Language, and Region > Change keyboards or
other input methods" to configure the keyboard properties. To access the Windows
operating system, press the Windows key on the external keyboard.

Preparing for Use
Windows Operating System
2.5 Windows Operating System
The instrument contains the Windows Embedded Standard operating system which
has been configured according to the instrument's features and needs. Changes in the
system setup are only required when peripherals like keyboard or a printer are installed
or if the network configuration does not comply with the default settings. After the
R&S AMU is started, the operating system boots and the instrument firmware is started
automatically.
To ensure that the instrument software functions properly, certain rules must be
adhered to concerning the operating system.
Risk of causing instrument unusability
The instrument is equipped with the Windows Embedded Standard operating system.
Additional software can therefore be installed on the instrument. The use and installation of additional software may impair instrument function. Thus, run only programs
that Rohde & Schwarz has tested for compatibility with the instrument software.
The drivers and programs used on the instrument under Windows Embedded Standard
have been adapted to the instrument. Existing instrument software must always be
modified using only update software released by Rohde & Schwarz.
The following program packages have been tested:
●
R&S Power Viewer Plus - virtual power meter for displaying results of the Power
Sensor R&S NRP-Zxx (install only this component!)
●
Symantec Endpoint Security – Virus-protection software
●
FileShredder - for reliable deletion of files on the hard disk
In certain cases, the use of these programs can impair the performance of the instrument.
2.5.1 Virus Protection
Users must take appropriate steps to protect their instruments from infection. Beside
the use of strong firewall settings and regularly scanning any removable storage device
used with a Rohde & Schwarz instrument, it is also recommended that anti-virus software be installed on the instrument. While Rohde & Schwarz does NOT recommend
running anti-virus software in the background ("on- access" mode) on Windows-based
instruments, due to potentially degrading instrument performance, it does recommend
running it during non-critical hours.
For details and recommendations, see the Rohde & Schwarz White Paper 1DC01:
Malware Protection.

2.5.2 Service Packs and Updates
Microsoft regularly creates security updates and other patches to protect Windowsbased operating systems. These are released through the Microsoft Update website
and associated update server. Instruments using Windows, especially those that connect to a network, should be updated regularly.
For details and recommendations, see the Rohde & Schwarz White Paper 1DC01:
Malware Protection.
2.5.3 Login
Windows Embedded Standard requires that users identify themselves by entering a
user name and password in a login window. The instrument provides a factory-installed
auto login function, i.e. login is carried out automatically in the background. The ID
used for autologin has administrator rights so that printer and network installations are
possible. The user name and password are set to "instrument".
2.5.4 Accessing the Start Menu
All necessary system settings can be defined in the "Start > Control Panel" menu (for
required settings refer to the Windows Embedded Standard documentation and to the
hardware description).
Energy saving mode
An energy saving mode is a default setting in the instrument. The hard disk switches to
power-save mode if it is not accessed for 30 minutes. The energy-saving mode is exited by accessing the hard disk again.
2.6 Setting Up a Network (LAN) Connection
The R&S AMU 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 Windows firewall configuration is adapted accordingly, the interface can be used, for example:
●
To transfer data between a controlling device and the test device, e.g. in order to
run a remote control program.
See chapter "Remote Control" in the R&S AMU User Manual.
●
To access or control the measurement from a remote computer using the "Remote
Desktop" application (or a similar tool)
●
To connect external network devices (e.g. printers)
●
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
LXI
The R&S AMU complies with LXI Class C. LXI gives you direct access to the LAN settings described below.
Accessing Operating System
The operating system can only be accessed if an external keyboard and/or a mouse is
connected. Windows provides an on-screen keyboard that can be operated using a
mouse, thus enabling operation by mouse only. An external keyboard is recommended
for extensive entries.
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 made with an ordinary RJ-45 network cable. The instrument is assigned
an IP address and can coexist with a computer and with other hosts on the same
network.
●
A dedicated network connection (Point-to-point connection) between the instrument and a single computer made with a (crossover) RJ-45 network cable. The
computer must be equipped with a network adapter and is directly connected to the
instrument. The use of hubs, switches, or gateways is not required, however, data
transfer is still performed using the TCP/IP protocol. An IP address has to be
assigned to the instrument and the computer, see Chapter 2.6.2, "Assigning the IP
Address", on page 37.
The R&S AMU uses the IP addresses 192.168.xxx.yyy for this purposes, where
xxx and yyy may take values between 1...254; the subnet mask is always
255.255.255.0.
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.
► To establish a non-dedicated network connection, connect a commercial RJ-45
cable to one of the LAN ports.
To establish a dedicated connection, connect a (crossover) RJ-45 cable between
the instrument and a single PC.
If the instrument is connected to the LAN, Windows automatically detects the network
connection and activates the required drivers.
36Quick Start Guide 1402.5200.62 ─ 08
Page 53
R&S®AMU200A
Preparing for Use
Setting Up a Network (LAN) Connection
The network card can be operated with a 10 Mbps Ethernet IEEE 802.3 or a 100 Mbps
Ethernet IEEE 802.3u interface.
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, 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.
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 manually
1. Obtain the IP address and subnet mask for the R&S AMU and the IP address for
the local default gateway from your network administrator. If necessary, also obtain
the name of your DNS domain and the IP addresses of the DNS and WINS servers
on your network. If you use more than one LAN connector, you need separate
address information for each connector.
2. Press the "Windows" key to access the operating system.
3. Open the "Control Panel" by selecting "Start > Settings > Control Panel".
4. Select "Network Connections".
5. Right-click "Local Area Connection" and select "Properties" from the context-sensitive menu, or
click "Local Area Connection" and then "File > Properties".
6. On the "General" tab, click "Internet Protocol (TCP/IP)" and then select "Properties".
7. Select "Use the following IP address" and enter the address information as
obtained from the network administrator.

8. If necessary, you can also select "Use the following DNS server addresses" and
enter your own DNS addresses.
For more information refer to the Windows Help.
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.
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 "Windows" key to access the operating system.
2. Select "Start > My Computer > Properties > Computer Name".
The computer name is displayed under "Full Computer Name".
3. To change the computer name, select "Change", enter the new computer name
and confirm the entry.
2.6.4 Changing the Windows Firewall Settings
A firewall protects an instrument by preventing unauthorized users from gaining access
to it through a network. Rohde & Schwarz highly recommends the use of the firewall on
your instrument. Rohde & Schwarz instruments are shipped with the Windows firewall
enabled and preconfigured in such a way that all ports and connections for remote
control are enabled.
For more details on firewall configuration, see the Rohde & Schwarz White Paper
1DC01: Malware Protection.
Note that changing firewall settings requires administrator rights.
38Quick Start Guide 1402.5200.62 ─ 08
Page 55
R&S®AMU200A
Preparing for Use
Setting Up a Network (LAN) Connection
To transfer waveform files generated on an external PC using R&S WinIQSIM2, you
have to disable the firewall.
Risk of Unauthorized Access
Disabling the firewall or allowing exceptions may make your instrument more vulnerable to viruses and intruders.
It is recommended that you restore the default firewall configuration after completing a
task which requires modified settings.
2.6.5 Working with Directories
Access to network drives depends on access rights and whether the drives in question
have been enabled. The complete integration of the R&S AMU into a larger network
with the necessary allocation of rights is highly complex and normally performed by a
network administrator.
However, the hard disk of a computer also connected to the network can be accessed
from the instrument relatively easily. The only precondition is that the directory on the
remote computer that the instrument should access is enabled for remote access. Subsequently, this directory is accessed from the instrument using a Windows Embedded
Standard search function. This procedure is also of importance for a point-to-point connection, for instance in order to start a firmware update for which the files have been
stored on the hard disk of the remote computer.
The computer and the instrument must both be provided with a computer name and an
IP address (see Chapter 2.6.2, "Assigning the IP Address", on page 37).
Enabling directories on the remote computer
The menu name may deviate from the name specified in the operating sequence,
depending on the language and on the operating system used on the computer.
1. On the remote computer, in Windows Explorer, click the directory to be enabled.
2. From the context menu, select "Properties".
3. Select the "Sharing" tab and enable "Share this folder".
Accessing the enabled directory
1. On the instrument, select "Start > Search > For Files and Folders > Printers, Computers > A Computer in the Network".
2. Enter the computer name and press ENTER to start the search.

The files in this directory can be accessed by the instrument.
2.7 Remote Access via an External Controller
The R&S AMU 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 63.
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 programs "Remote Desktop" for PCs with windows
operating system, or "Ultr@VNC" for PCs with Linux/Unix or Windows operating system are available for setting up the remote access connection. Using these applications requires additional installation.

2.7.3 Remote Access via a VNC Client Software
A VNC client software is an application which can be used to access and control the
instrument from a remote computer via LAN.
The following description explains how to establish the remote access, represented by
means of the client software Ultr@VNC. The software is included in Linux/Unix operating system, but it is also available as a free-of-charge download on the Internet http://
www.uvnc.com/download/index.html. Thus, it is also available for remote computers
with Windows operating system.
The GUI appearance of Ultr@VNC may vary if you use a later release. Also, similar
programs may deviate in some details, but the basic procedure is the same.
Risk of Unauthorized Access
If the VNC service is enabled on the instrument, any user in the network who knows
the computer name and password can access it.
Disable the VNC service on the instrument to prevent unauthorized access.

2.9 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.
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 easy identificate the instrument.
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:
52Quick Start Guide 1402.5200.62 ─ 08
Page 69
R&S®AMU200A
Preparing for Use
LXI Configuration
●
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 VXI-11 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.
For information about the LXI standard refer to the LXI website at http://www.lxistan-
dard.org. See also "News from Rohde & Schwarz, article 2006/II - 190".
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 AMU complies with LXI class C and provides an integrated "LXI Status" dialog for LXI status indication and reset of the LAN configuration (LAN Configuration Initialize, LCI). To accesss the LXI Status dialog, press the SETUP key and select
"Remote > LXI Status".
For further information, see section "LXI Status" in the Operating Manual.

Brief Introduction to the Instrument's Concept
This section helps you to get familiar with the R&S AMU and provides an introduction
to the general concept of the instrument with a sample of the possible application fields
as well as 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 R&S AMU provides an entirely digital baseband section for generating I/Q signals.
The R&S AMU uses internal and/or external baseband signal sources and simulates
various interfering signals in the baseband, e.g. fading, noise and I/Q impairment. Digital signals can be generated internally in accordance with several digital standards or
user defined signal characteristics. Analog or digital baseband signals can be fed into
the signal path. The signals are generated in realtime or with the aid of the Arbitray
Waveform Generator. The digital data streams can be output directly and are converted to analog I/Q baseband output signals.
The R&S AMU may contain two paths; through the user docmentation, the first being is
called path A and the second path B, respectively.
The signals generated in different basebands blocks can be routed from path A to path
B and vice versa and can be added. Each baseband path enables independent output
of the modulated signals (analog in/out, digital in/out, analog differential out).
For a detailed description of the blocks, refer to Chapter 3.3, "Baseband Section",
on page 70.
The operating concept of the R&S AMU employs the following three ways of instrument control:
●
Manual operation
●
Remote control
●
Remote access
Manual Operation
The R&S AMU can be entirely operated from the front panel. Peripherals such as
mouse or keyboard can be connected but are not essential.
The R&S AMU 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.

Brief Introduction to the Instrument's Concept
Each block represents a functional unit of the instrument. Thus the user always knows
the position at which a parameter has an effect in 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.
Figure 3-1: Block diagram of a fully equipped R&S AMU
With the aid of the rotary knob, the user can navigate in the block diagram and the dialogs, and can 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. Context-sensitive
help can be called any time with the HELP (F1) key. 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.

Applications of the Instrument
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 87.
For an indepth description of the dialog boxes and the instrument functions refer to
section "Instrument Functions" in the Operating Manual.
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 AMU 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
Tip: For remote control over LAN, you can use the R&S VISA (Virtual Instrument Soft-
ware 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 operating manual, chapter "Remote Control Basics". The
description of the remote control commands is provided in the operating manual, chapter "Remote Control Commands".
Remote Access
Remote access is the operating of the instrument from a remote computer. Both the
R&S AMU 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 40.
3.2 Applications of the Instrument
The modular design of the R&S AMU allows the instrument to be equipped with two
paths. This allows a multitude of applications to be performed for which several signal

3.2.1 Generation of Digitally Modulated Signals
The main field of application of the R&S AMU is the generation of digitally modulated
signals. In the instrument, a digitally modulated signal can be generated in several
ways.
Internally generated I/Q signal
The I/Q signal is generated internally in the R&S AMU. One or two baseband generators can be installed. The signals produced by the two generators can be added (possibly with frequency offset).
In this case the instrument must be equipped with
●
at least one baseband generator (option R&S AMU-B9/-B10/-B11) and
●
at least one baseband main module (option R&S AMU-B13).
Fading scenarios can be created with the aid of a fading module (option R&S AMUB14, Fading Simulator) and option R&S AMU-B15, Fading Simulator Extension).
A digital/analog converter converts the internal digital baseband signals into analog I/Q
output signals. The output of the analog signal can be single ended or differential
(option R&S AMU-B16; Differential I/Q Output). For the digital signal output a baseband digital I/Q output (option R&S AMU-B18, Baseband Digital I/Q Output) is available.

Figure 3-2: Operation of the R&S AMU with I/Q signals generated by the internal baseband generator
Externally generated I/Q signal
The I/Q signal is generated by an external instrument and coupled in via the baseband
input module (option R&S AMU-B17, Baseband I/Q Input (digital/analog)). With this
baseband input module, analog or digital signals can be fed into the R&S AMU. The
frequency of the signals can be shifted, and if options are installed for internal baseband generation, the external and the internal baseband signals can be added with
variable level ratio. If the R&S AMU is equipped with a fading simulator (option
R&S AMU-B14, Fading Simulator and option R&S AMU-B15, Fading Simulator Extension), the signals can be faded. The fading module also processes external I/Q signals.

3.2.2 One Path Instrument
A one-path R&S AMU requires at least one Baseband Main Module (option R&S AMUB13) and a signal source. The signal source may be either the internal Baseband Generator (option R&S AMU-B9/-B10/-B11) or the external Baseband I/Q Input (option
R&S AMU-B17).

A two-path R&S AMU requires at least two Baseband Main Modules (option
R&S AMU-B13) and two signal sources. The signal sources may be the internal Baseband Generators (option R&S AMU-B9/-B10/-B11) or the external Baseband I/Q Inputs

3.3 Baseband Section
The baseband section of the R&S AMU is fully digital and contains the hardware for
generating and processing I/Q signals.
The baseband section may contain two paths.
For detailed information on available options, refer to the R&S AMU data sheet and the
R&S AMU configuration guide.
Up-to-date information is available at R&S AMU homepage on the internet http://
www.rohde-schwarz.com/product/amu200a.html.
Baseband generator (option R&S AMU-B10)
The generator produces baseband signals. It contains modules for real time signal
generation and an arbitrary waveform generator (ARB).
The different baseband options feature a different ARB memory size (see data sheet).
But apart from the memory size, all options have the same functionality and are installed alternatively.
One or two baseband generators can be fitted in an R&S AMU and operated separately. Signals from the baseband generators can be routed from path A to B and vice
versa, and added (possibly with frequency offset).
The option Baseband Generator contains real time Custom Digital Modulation and
ARB. Software options providing various digital standards are offered in addition.
Option R&S AMU-K40, for instance, generates signals to GSM/EDGE standard, option
R&S AMU-K42 signals to 3GPP FDD standard.
Baseband input module (option R&S AMU-B17)
With the aid of this module, external analog or digital I/Q signals can be fed into the
R&S AMU. For two-path instruments, an external signal can be connected to baseband
70Quick Start Guide 1402.5200.62 ─ 08

Baseband Section
path A or path B. For one-path instruments, the baseband input module is permanently
linked to path A. Up to two baseband input modules can be applied. In two-path instruments the signal of the first baseband module can be routed to path A, path B or to
both paths. The signal of the second baseband input module is firmly connected to
path B. External and internal baseband signals can be added with variable level ratio.
The I/Q signals can be further processed: e.g. the frequency of the signals can be shifted, noise can be added and they can also be faded.
The R&S AMU-B17 option can be used together with the R&S® EX-IQ-BOX digital
interface module, providing a versatile digital baseband interface with various formats.
The baseband main module can be installed twice, for each of both paths A and B
respectively.
The module converts the digital signal to an analog I/Q signal and routes it to the I/Q
output. The analog I/Q signal can be output either single ended, or differential.
This module also offers digital I/Q impairment functions. The I/Q signal can be deliberately corrupted, e.g. for testing the receiver quality.
All frequency and time settings are coupled to the internal reference frequency.
Additional White Gaussian Noise (option R&S AMU-K62)
Additive white noise, which may be required for instance for measurements on mobile
radio base stations, can be produced with the AWGN software option (R&S AMU-K62).
If the noise generator is used, a frequency offset cannot be added to the wanted signal. If two options R&S AMU-B13 are installed (paths A and B), AWGN can be generated either on path A or B with one R&S AMU-K62 option. If AWGN is to be generated
on paths A and B simultaneously, two options R&S AMU-K62 must be installed.
Fading module (option R&S AMU-B14)
This module enables fading effects to be produced on baseband signals in real time. In
the case of TDMA fading, up to 20 fading paths (40 fading paths with option
R&S AMU-B15) can be created simultaneously.
Software option R&S AMU-B71 comprises the 3GPP dynamic fading configurations
moving propagation and birth-death propagation as well as the fine delay fading configurations offering enhanced delay resolution.
At least one fading simulator, option R&S AMU-B14 must be installed. If both options
R&S AMU-B14 and the R&S AMU-B15 are installed (signal path A and B), dynamic
fading and enhanced resolution can be used either on signal path A or B with one
option R&S AMU-K71 option. If dynamic fading and enhanced resolution is to be used
on signal paths A and B simultaneously, two options R&S AMU-K71 must be installed.

Differential output module (option R&S AMU-B16)
The differential output module (option R&S AMU-B16) provides symmetrical signals for
differential outputs. The operating points of the inputs can be set and balanced by an
offset between inverting and non-inverting output. This module can be installed twice
(for path A and path B).
Digital output module (option R&S AMU-B18)
The R&S AMU can be equipped with a standardized digital I/Q interface (LVDS) for
online transfer of digital I/Q data. The digital output module (option R&S AMU-B18)
enables the digital output of the I/Q baseband signal.
This module can be installed twice (for path A and path B).
The R&S AMU-B18 option can be used together with the R&S® EX-IQ-BOX digital
interface module, providing a versatile digital baseband interface with various formats.
3.3.1 Description of Individual Diagram Blocks of the Baseband Section
The baseband section of the R&S AMU comprises two paths (paths A and B). Therefore, if two baseband generators are available, two baseband signals can be processed independently of each other. Routing from path A to path B and vice versa is
also possible, but not after the "IMP" or "AWGN/IMP" block.
Each function block can be activated or deactivated with the "ON" check box (on/off
toggling).
The ON/OFF TOGGLE key at the front panel (see "TOGGLE" on page 15) switches
the currently selected block on or off.
A detailed description of the blocks is provided below.
Baseband A block
In this block, the (first) baseband source is configured and activated. The block is displayed only if a baseband generator is available in the instrument.
Depending on the installed software options, various digital standards, user-configured
digital real time modulation or the built-in waveform generator (ARB) can be selected.
The selected modulation is displayed in the block.
External Baseband In block
This block controls the baseband input module for external I/Q signals. The block is
displayed only if the baseband input module (option R&S AMU-B17) is installed. External I/Q signals can be applied to the analog I/Q input. The output of the baseband input
module can be connected to baseband path A or (if available) path B provided at least
one baseband main module or one fading module is installed. Otherwise the baseband
input module is permanently linked to path A. (The reason is that the baseband input
module does not contain a router chip. For switchover, at least one baseband module
with a router chip is required).

Baseband Section
Note: If one baseband path is configured (path A), the external baseband signal BB
Input B is connected to this path. If two baseband paths are configured the external
baseband signal BB Input B is permanently routed to path B.
Baseband B block
Configures the second baseband source (if installed). The block is displayed only if the
instrument contains two baseband generators. Depending on the installed software
option, various digital standards, user-configured digital real time modulation or the
built-in waveform generator (ARB) can be selected.
Note: If two baseband generators are installed and two signals of the same standard
(e.g. GSM/EDGE) should be output simultaneously, the two associated software
options must also be installed (in this case R&S AMU-K40).
If only one R&S AMU-K40 is installed and GSM/EDGE is selected in the first baseband
generator, the second baseband generator is disabled for GSM/EDGE.
However, a software option is not tied to a specific baseband generator. In our example, either the first or the second baseband generator can output a GSM/EDGE signal.
Fading block
This block controls the fading module. It is displayed only if a fading simulator (option
R&S AMU-B14) is installed. Signal routing at the output of the fading module is also
configured in this block.
For instance, two-channel fading can be selected if the instrument contains two baseband paths and two faders (option path extension, R&S AMU-B15).
Note: Under certain signal routing conditions only one fader can be activated
At least one fading simulator, option R&S AMU-B14 must be installed. If both options
R&S AMU-B14 and the R&S AMU-B15 are installed (signal path A and B), dynamic
fading and enhanced resolution can be used either on signal path A or B with one
option R&S AMU-K71 option. If dynamic fading and enhanced resolution is to be used
on signal paths A and B simultaneously, two options R&S AMU-K71 must be installed.
AWGN/IMP A block
In this block (digital) I/Q impairments for the baseband path can be set. With the aid of
the software for AWGN generation (option R&S AMU-K62), an (additive) noise signal
can be produced.
AWGN and impairments can be activated independently of each other in the appropriate menus. The settings are displayed in the block. The entire block can be activated
or deactivated. If the block is deactivated, the signal passes through the block
unchanged.
AWGN/IMP B block
This block is displayed only if two baseband main modules (option R&S AMU-B13) are
installed. In this block (digital) I/Q impairments for baseband path B can be set. With
the aid of the software for AWGN generation (option R&S AMU-K62), an (additive)
noise signal can be produced in path B.
If a noise signal should be applied to path A and B simultaneously, two software
options R&S AMU-K62 are required.

Graphics block
With this block, the baseband signal (of path A or B) can be graphically displayed in
real time. The block is displayed only if at least one baseband main module is installed.
BERT block
In this block an integrated bit and block error rate tester can be set. The bit error tester
makes it possible to evaluate a signal demodulated and decoded by a DUT by measuring the bit error rate. The data used to drive the DUT can be generated by the
R&S AMU or an user-defined external source. In addition, the block error rate measurement can be used to verify CRC checksums.
I/Q OUT A/B blocks
These blocks are used to configure the digital and analog I/Q outputs of path A. Configurations like level display, output type, analog settings and digital settings can be
performed in the corresponding menus. I and Q components can also be swapped (I/Q
Swap).
The status line in a block displays the currently active output types, e.g. "DIFF DIGI"
denotes that the I/Q baseband signal is provided by the analog output (in differential
mode) and also by the digital output.
Note: The BASEBD ON/OFF key switches the baseband output signal on and off. In
the two-path mode this key switches all signals off. A second stroke restores the status
that was active before the last switch off.
