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 - 09 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 - 09 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 - 09 Page 11

Instrucciones de seguridad elementales

17. No utilice el producto en condiciones en las que pueda producirse o ya se hayan producido
condensaciones sobre el producto o en el interior de éste, como p. ej. al desplazarlo de un lugar frío a
otro caliente. La entrada de agua aumenta el riesgo de choque eléctrico.

18. Antes de la limpieza, desconecte por completo el producto de la alimentación de tensión (p. ej. red de
alimentación o batería). Realice la limpieza de los aparatos con un paño suave, que no se deshilache.
No utilice bajo ningún concepto productos de limpieza químicos como alcohol, acetona o diluyentes
para lacas nitrocelulósicas.

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

1171.0000.42 - 09 Page 12

Instrucciones de seguridad elementales

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.

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.

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

21User Manual 1178.3834.02 ─ 03

R&S®SMA100B

Getting Started

Preparing for Use

Risk of injury when stacking instruments

A stack of instruments can tilt over and cause injury if not stacked correctly. Further­more, the instruments at the bottom of the stack can be damaged due to the load
imposed by the instruments on top.

Observe the following instructions when stacking instruments:

●

Never stack more than three instruments. If you need to stack more than three
instruments, install them in a rack.

●

The overall load imposed on the lowest instrument must not exceed 500 N.

●

It is best if all instruments have the same dimensions (width and length).
If you need to stack smaller instruments on the top, the overall load imposed on the
lowest instrument must not exceed 250 N.

●

If the instruments have foldable feet, fold them in completely.

Mounting in a rack

The R&S SMA100B can be installed in a rack using a rack adapter kit (Order No. see
data sheet). The installation instructions are part of the adapter kit.

Risk of instrument damage due to insufficient airflow in a rack

If the instrument is run with insufficient airflow for a longer period, the instrument over­heats, which can disturb the operation and even cause damage.

Make sure that all fan openings are unobstructed, that the airflow perforations are
unimpeded, and that the minimum distance from the wall is 10 cm.

2.1.1.5 Connecting AC Power

The R&S SMA100B is equipped with an AC power supply connector, that can be oper­ated with different AC power voltages. Once it is connected, the instrument automati­cally adjusts to the given voltage. Refer to the data sheet for the requirements of volt-

●

Power sensors of the R&S NRP families

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

Connecting a USB storage device

When a USB storage device like a memory stick, a CD-ROM drive, or a hard disk is
connected, it is detected automatically. The device is made available as a new drive (/
usb). The name of the drive is manufacturer-dependent.

Connecting a keyboard

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

Use the "Setup > User Interface > USB Keyboard Settings" dialog to configure the key­board properties (see Chapter 2.1.4.2, "Setting the Keyboard Language",

2.1.3 Setting Up a Network (LAN) Connection

The R&S SMA100B 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, the interface can be used, for example:

●

To transfer data between a controller and the instrument, for example to run a
remote control program.
See Chapter 11, "Network Operation and Remote Control", on page 244.

●

To access or operate the instrument from a remote computer using the Ultr@VNC
program (or a similar tool, like another VNC client or any Web browser supporting
Java).

●

To transfer data from a remote computer and back, for example using network fold­ers.

●

To transfer data between R&S NRP power sensors and the instrument.

This section describes how to configure the LAN interface.

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.

2.1.3.1 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

For addressing, both the instrument and the computer reqiure an IP address. The
address information is usually assigned to the devices automatically, depending on the
network capabilities.

If the IP address is not assigned automatically, see Chapter 2.1.3.3, "Assigning the IP

Address", on page 28 for information on how to assign the address manually.

Preparing for Use

To set up a network (LAN) connection

Risk of network failure

Consult your network administrator before performing the following tasks:

●

Connecting the instrument to the network

●

Configuring the network

●

Changing IP addresses

●

Exchanging hardware

Errors can 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
to obtain the whole address information automatically.

When connected, the R&S SMA100B displays the address information on the
screen.

Risk of network connection failure

Network cables and cable connectors of poor quality, or failures in the autonegotiation
process, can 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 "Troubleshooting and Error Messages".

2.1.3.2 Using Computer Names (Hostnames)

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

Each instrument is delivered with an assigned computer name, that remains perma­nent as long as it is not explicitly changed.

27User Manual 1178.3834.02 ─ 03

R&S®SMA100B

Getting Started

Preparing for Use

The default computer name follows the syntax <INST>-<Serial Number> (previous
syntax: rs<inst><Serial Number>), where:

●

<INST> is the short name of your instrument, as stated on the front panel.

●

<Serial Number> is the individual serial number of the instrument.
You can find the serial number at the rear panel of instrument. It is the third part of
the device ID printed on the barcode sticker .

Example:

The default hostname of an R&S SMA100B with a serial number 102030 is
SMA100B-102030.

To query and change a computer name

1. Press the SETUP key.

2. Select "Remote Access > Network".
The "Network Settings" dialog opens.

The computer name is displayed under "Hostname".

3. Press the SETUP key.

4. Select "Security > Protection".

5. Enable the "Protection Level 1".
The default password is 123456.

The parameter "Hostname" in the "Network Settings" dialog is now enabled for
configuration.

6. Change the "Hostname".

2.1.3.3 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 DHCP (Dynamic
Host Configuration Protocol), the address information is 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.

Since the dynamic TCP/IP configuration assigns the address information automatically,
it is safe to establish a physical connection to the LAN without any previous instrument
configuration.

2.4.1 Possible Ways to Operate the Instrument

There are three ways to operate the R&S SMA100B:

●

Manual operation:
Use the touchscreen, hard keys and rotary knob, or an optional mouse and/or key­board. The principles of manual operation are explained in Chapter 2.4, "Instru-

ment Control", on page 51.

●

Remote control:
Create programs to automatize repeating settings, tests and measurements. The
instrument is connected to a computer running the program.
This way of operation is described in Chapter 11, "Network Operation and Remote

Control", on page 244.

●

Remote operation from a computer:
Remote monitoring and control of the instrument from a connected computer is
based on the common cross-platform technology VNC (Virtual Network Comput­ing). On the remote computer, any standard web browser (supporting Java) or a
dedicated VNC client (like Ultr@VNC) can be used. See also Chapter 2.4.8,

"Remote Operation over VNC", on page 61.

2.4.2 Means of Manual Interaction

For the manual interaction with the R&S SMA100B, you have several methods that you
can use as an alternative to perform a task:

●

Touchscreen:
Touchscreen operation is the most direct way to interact. Almost all control ele­ments and actions on the screen are based on the standard operating system con­cept. You can tap any user interface element to set parameters in dialog boxes,
enter data, scroll within a dialog etc., as if you work with a mouse pointer.

Tapping the screen works like clicking mouse buttons:
– Touch quickly = click: Selects a parameter or provokes an action.
– Touch and hold = right-click: Opens a context-sensitive menu.
– Touch and swipe = drag: Scrolls through the contents of a display element

larger than the screen, e.g. a list or a table.

●

Function keys and rotary knob:
The front panel provides nearly all functions and controls to operate the instrument
in the classic way, without touchscreen.

3 RF Signal Configuration

RF Signal Configuration

The R&S SMA100B signal generator generates RF signals with outstanding spectral
purity within the frequency range from 8 kHz up to 6 GHz and with adjustable signal
level over a wide range.

In addition to these real-time CW signals, you can also generate RF signals from pre­defined lists and sweep signals that vary according to the frequency or amplitude
curves.

Moreover, you can apply versatile analog modulation types with definable characteris­tics.

The variably adjustable output level due to the built-in attenuator, allows you to vary
the RF signal level over the full level range. There are different methods to improve
signal performance and to optimize the signal quality for the particular application, or to
increase the accuracy and reliability of the generated RF signal.

In addition, the R&S SMA100B supports R&S NRP power sensors. Power sensors can
be used to monitor the output level in the generator and to determine the level correc­tion values for user correction lists.

Signal modes and characteristics

The R&S SMA100B generates unmodulated or analog modulated RF signals. You can
output the signal in fixed mode or as a signal having periodically varying frequencies or
amplitudes.

Signal modes for RF signal generation:

●

Unmodulated signal
Generates an unmodulated continuous wave (CW) of constant frequency and
amplitude.

For information on the signal frequency and level settings and example on how to
configure a simple CW signal, see:

– Chapter 3.3, "RF Frequency Settings", on page 65
– Chapter 3.4, "RF Level Settings", on page 67
– Chapter 2.3.1, "Generating an Unmodulated Carrier", on page 44

●

Analog modulated signal
Modulates the signal with an analog signal and generates amplitude, phase, fre­quency and pulse modulation.
See Chapter 4, "Analog Modulations", on page 74.

RF signal output modes:

●

Fixed
The RF signal as it is, that means modulated or unmodulated.

●

Sweep
An RF or LF frequency and RF level sweep signal, processed continuously, step­by-step or individually and with selectable trigger modes. Different sweeps cannot
run simultaneously.

●

List mode

3.1 Activating RF Signal Output

Per default, the RF output signal is deactivated.

To activate the RF output

1. Configure the RF signal as required.
Set for example the frequency and level values.

2. Activate the RF output in one of the following ways:
a) Select "Level > RF ON > On"

b) Press the RF ON/OFF key at the front panel.

3. In the "Level" tile, observe the color of the "RF On" icon.

The blue color indicates that the RF output is activated.

You can query the impedance of the RF output.
Remote command:

:OUTPut<hw>:IMPedance? on page 349

3.2 How to Set the Frequency and Level

The simplest form of the RF signal is a continuous wave (CW) of constant frequency
and amplitude. Such an unmodulated signal transmits the information without varying
the carrier signal as with a modulation, for example. The RF signal is defined by its fre­quency, level and phase.

► Use one of the following:

● "Status Bar > Frequency and Level"

● "Frequency panel > Frequency"

How to Set the Frequency and Level

● "Level panel > Level"

● "Frequency panel > Frequency > Phase"

● On the front panel, press the FREQ or the LEVEL key.

Current frequency and level values are indicated on the "Status bar" so that you can
see them at a glance. Values displayed in the status bar and in the "Frequency/Level"
dialogs can deviate form each other.

See "RF frequency and level display with a downstream instrument" on page 64.

RF frequency and level display with a downstream instrument

If your test setup includes a downstream instrument, you can enter the parameter of
the downstream instrument in the frequency or level settings dialog of the
R&S SMA100B. Examples of downstream instruments are mixers, frequency multipli­ers, amplifiers or attenuators and of their corresponding major parameters offset, multi­plier, amplitude.

The R&S SMA100B generates the signal without the downstream parameters, but con­siders all additional parameters concerning the frequency and level, like frequency off­set and multiplication factor, or user correction. Any of these cases is indicated by a
dedicated icon, displayed in the "Frequency" or "Level" tile, depending on the affected
parameter.

4 Analog Modulations

Analog Modulations

Modulation Types and Signal Sources

The R&S SMA100B supports AM (amplitude modulation), FM (frequency modulation),
ΦM (phase modulation (PhiM)), and also PULM (pulse modulation). It generates low
frequency signals (LF) as sine, triangle, trapezoidal or square (pulse) waveform, that
can be output and further processed by a downstream instrument.

4.1 Required Options

R&S SMA100B base unit equipped with the following options:

●

Option frequency (R&S SMAB-B10x)

●

Option pulse modulator (R&S SMAB-K22)

●

Option pulse generator (R&S SMAB-K23)
(supports generation of single and double pulse signals)

●

Option multi-function generator (R&S SMAB-K24)

●

Option pulse train generator (R&S SMAB-K27)
(requires R&S SMAB-K23)

●

Option AM/FM/PhiM, up to 6 GHz (R&S SMAB-K720)

For more information, see data sheet.

4.2 Modulation Types and Signal Sources

Radio transmitters do not transmit an audio signal directly. Instead, they modulate the
audio signal onto a continuous wave (CW) carrier with much higher frequency.

A CW carrier has a sinusoidal waveform with constant amplitude and constant fre­quency. Modulating a signal onto the carrier means varying a property of the carrier
according to the modulating signal. The three basic modulation types FM, AM and
PhiM for example, vary one property of the carrier proportional to the instantaneous
amplitude of the modulating signal.

Signal sources

If fully equipped, the R&S SMA100B modulates signals from the following sources:

●

Internal modulation source

– Two LF generators

Supplie sinusoidal and square waves in the frequency range 0.1 Hz to 10 MHz
and selectable shapes.
The R&S SMA100B generates any other modulation signal shapes (triangle,
trapezoid and square wave or a pulse signal) by converting the sinusoidal sig­nal

– Multifunction generator and a noise generator

Analog Modulations

Modulation Types and Signal Sources

A further LF generator for use as a second modulation source or to generate a
noise modulation signal
The noise generator supplies white noise with selectable bandwidth and level
distribution.

– High-performance pulse generator

Generates double pulse or pulse train signals.

●

External modulation source

– Amplitude, frequency or phase modulation signals are input at the EXT connec-

tor

– Pulse modulation signals, at the PULSE EXT connector.

Signal output

You can perform the AM, FM and PhiM with the signal of any of the provided sources.
Moreover, you can combine two modulation signals and generate a two-tone signal.
Regardless of the signal source, the generated signal, can be output for further pro­cessing in a downstream instrument.

Current configuration is indicated in the Chapter 4.4.8, "Overview", on page 104 dia­log; the output signal routing can be changed, too.

"Auto"

Generates a single pulse in one pulse period.
Generates two pulses in one pulse period.
Option: R&S SMAB-K27

Generates a user-defined pulse train.
See Chapter 4.4.3.2, "Pulse Generator > Pulse Train Settings",
on page 87.

Generates the modulation signal continuously.

"Ext Triggered"

Generates the signal each time an external trigger event occurs.

Example: Generation of single pulse signal ("Pulse Mode = Sin­gle") using "Trigger Mode = Ext Triggered"

1 = External trigger signal input with "Trigger Input Polarity = Normal" (the positive

slope is active)
2 = Sync signal
3 = Pulse signal
Δt = Typically 50 ns, see data sheet (trigger delay between the trigger and the sync

signal start)
delay = "Pulse Delay = 100 ns"
PW = "Pulse Width = 100 ns"

Example: Generation of double pulse signal ("Pulse Mode = Dou­ble") using "Trigger Mode = Ext Triggered"

= External trigger signal input with "Trigger Input Polarity = Normal" (the positive

1

slope is active)
2 = Sync signal
3 = Pulse signal
a = Trigger signal during double pulse generation is without effect
