Basic Safety Instructions
Operating states and operating positions
The product may be operated only under the operating conditions and in the positions specified by the
manufacturer, without the product's ventilation being obstructed. If the manufacturer's specifications are
not observed, this can result in electric shock, fire and/or serious personal injury or death. Applicable local
or national safety regulations and rules for the prevention of accidents must be observed in all work
performed.
1. Unless otherwise specified, the following requirements apply to Rohde & Schwarz products:
predefined operating position is always with the housing floor facing down, IP protection 2X, use only
indoors, max. operating altitude 2000 m above sea level, max. transport altitude 4500 m above sea
level. A tolerance of ±10 % shall apply to the nominal voltage and ±5 % to the nominal frequency,
overvoltage category 2, pollution degree 2.
2. Do not place the product on surfaces, vehicles, cabinets or tables that for reasons of weight or stability
are unsuitable for this purpose. Always follow the manufacturer's installation instructions when
installing the product and fastening it to objects or structures (e.g. walls and shelves). An installation
that is not carried out as described in the product documentation could result in personal injury or
even death.
3. Do not place the product on heat-generating devices such as radiators or fan heaters. The ambient
temperature must not exceed the maximum temperature specified in the product documentation or in
the data sheet. Product overheating can cause electric shock, fire and/or serious personal injury or
even death.
Electrical safety
If the information on electrical safety is not observed either at all or to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.
1. Prior to switching on the product, always ensure that the nominal voltage setting on the product
matches the nominal voltage of the mains-supply network. If a different voltage is to be set, the power
fuse of the product may have to be changed accordingly.
2. In the case of products of safety class I with movable power cord and connector, operation is
permitted only on sockets with a protective conductor contact and protective conductor.
3. Intentionally breaking the protective conductor either in the feed line or in the product itself is not
permitted. Doing so can result in the danger of an electric shock from the product. If extension cords
or connector strips are implemented, they must be checked on a regular basis to ensure that they are
safe to use.
4. If there is no power switch for disconnecting the product from the mains, or if the power switch is not
suitable for this purpose, use the plug of the connecting cable to disconnect the product from the
mains. In such cases, always ensure that the power plug is easily reachable and accessible at all
times. For example, if the power plug is the disconnecting device, the length of the connecting cable
must not exceed 3 m. Functional or electronic switches are not suitable for providing disconnection
from the AC supply network. If products without power switches are integrated into racks or systems,
the disconnecting device must be provided at the system level.
5. Never use the product if the power cable is damaged. Check the power cables on a regular basis to
ensure that they are in proper operating condition. By taking appropriate safety measures and
carefully laying the power cable, ensure that the cable cannot be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.
1171.0000.42 - 08 Page 3
Basic Safety Instructions
6. The product may be operated only from TN/TT supply networks fuse-protected with max. 16 A (higher
fuse only after consulting with the Rohde & Schwarz group of companies).
7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket provided for this purpose. Otherwise, sparks that result in fire and/or injuries may occur.
8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric
shocks.
9. For measurements in circuits with voltages V
> 30 V, suitable measures (e.g. appropriate
rms
measuring equipment, fuse protection, current limiting, electrical separation, insulation) should be
taken to avoid any hazards.
10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC 60950-1 / EN 60950-1 or IEC 61010-1 / EN 61010-1 standards that
apply in each case.
11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in
operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the
product.
12. If a product is to be permanently installed, the connection between the protective conductor terminal
on site and the product's protective conductor must be made first before any other connection is
made. The product may be installed and connected only by a licensed electrician.
13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective
devices, the supply circuit must be fuse-protected in such a way that anyone who has access to the
product, as well as the product itself, is adequately protected from injury or damage.
14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of
lightning) can reach the product. Otherwise, the person operating the product will be exposed to the
danger of an electric shock.
15. Any object that is not designed to be placed in the openings of the housing must not be used for this
purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.
16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and
operating positions", item 1). Therefore, the equipment must be protected against penetration by
liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product
itself may be damaged, which can also lead to personal injury.
17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.
18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network
or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such
as alcohol, acetone or diluents for cellulose lacquers.
Operation
1. Operating the products requires special training and intense concentration. Make sure that persons
who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries
or material damage may occur. It is the responsibility of the employer/operator to select suitable
personnel for operating the products.
1171.0000.42 - 08 Page 4
Basic Safety Instructions
2. Before you move or transport the product, read and observe the section titled "Transport".
3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a
skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz
product, consult a physician immediately to determine the cause and to prevent health problems or
stress.
4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be
sure to read and pay special attention to the section titled "Waste disposal/Environmental protection",
item 1.
5. Depending on the function, certain products such as RF radio equipment can produce an elevated
level of electromagnetic radiation. Considering that unborn babies require increased protection,
pregnant women must be protected by appropriate measures. Persons with pacemakers may also be
exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take measures to avert the
potential danger.
6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can
cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and
protective clothing must be worn.
7. Laser products are given warning labels that are standardized according to their laser class. Lasers
can cause biological harm due to the properties of their radiation and due to their extremely
concentrated electromagnetic power. If a laser product (e.g. a CD/DVD drive) is integrated into a
Rohde & Schwarz product, absolutely no other settings or functions may be used as described in the
product documentation. The objective is to prevent personal injury (e.g. due to laser beams).
8. EMC classes (in line with EN 55011/CISPR 11, and analogously with EN 55022/CISPR 22,
EN 55032/CISPR 32)

Instrucciones de seguridad elementales
Funcionamiento
1. El uso del producto requiere instrucciones especiales y una alta concentración durante el manejo.
Debe asegurarse que las personas que manejen el producto estén a la altura de los requerimientos
necesarios en cuanto a aptitudes físicas, psíquicas y emocionales, ya que de otra manera no se
pueden excluir lesiones o daños de objetos. El empresario u operador es responsable de seleccionar
el personal usuario apto para el manejo del producto.
2. Antes de desplazar o transportar el producto, lea y tenga en cuenta el capítulo "Transporte".
3. Como con todo producto de fabricación industrial no puede quedar excluida en general la posibilidad
de que se produzcan alergias provocadas por algunos materiales empleados ―los llamados
alérgenos (p. ej. el níquel)―. Si durante el manejo de productos Rohde & Schwarz se producen
reacciones alérgicas, como p. ej. irritaciones cutáneas, estornudos continuos, enrojecimiento de la
conjuntiva o dificultades respiratorias, debe avisarse inmediatamente a un médico para investigar las
causas y evitar cualquier molestia o daño a la salud.
4. Antes de la manipulación mecánica y/o térmica o el desmontaje del producto, debe tenerse en cuenta
imprescindiblemente el capítulo "Eliminación/protección del medio ambiente", punto 1.
5. Ciertos productos, como p. ej. las instalaciones de radiocomunicación RF, pueden a causa de su
función natural, emitir una radiación electromagnética aumentada. Deben tomarse todas las medidas
necesarias para la protección de las mujeres embarazadas. También las personas con marcapasos
pueden correr peligro a causa de la radiación electromagnética. El empresario/operador tiene la
obligación de evaluar y señalizar las áreas de trabajo en las que exista un riesgo elevado de
exposición a radiaciones.
6. Tenga en cuenta que en caso de incendio pueden desprenderse del producto sustancias tóxicas
(gases, líquidos etc.) que pueden generar daños a la salud. Por eso, en caso de incendio deben
usarse medidas adecuadas, como p. ej. máscaras antigás e indumentaria de protección.
7. Los productos con láser están provistos de indicaciones de advertencia normalizadas en función de la
clase de láser del que se trate. Los rayos láser pueden provocar daños de tipo biológico a causa de
las propiedades de su radiación y debido a su concentración extrema de potencia electromagnética.
En caso de que un producto Rohde & Schwarz contenga un producto láser (p. ej. un lector de
CD/DVD), no debe usarse ninguna otra configuración o función aparte de las descritas en la
documentación del producto, a fin de evitar lesiones (p. ej. debidas a irradiación láser).
8. Clases de compatibilidad electromagnética (conforme a EN 55011 / CISPR 11; y en analogía con EN
55022 / CISPR 22, EN 55032 / CISPR 32)
Aparato de clase A:
Aparato adecuado para su uso en todos los entornos excepto en los residenciales y en aquellos
conectados directamente a una red de distribución de baja tensión que suministra corriente a
edificios residenciales.
Nota: Los aparatos de clase A están destinados al uso en entornos industriales. Estos aparatos
pueden causar perturbaciones radioeléctricas en entornos residenciales debido a posibles
perturbaciones guiadas o radiadas. En este caso, se le podrá solicitar al operador que tome las
medidas adecuadas para eliminar estas perturbaciones.
Aparato de clase B:
Aparato adecuado para su uso en entornos residenciales, así como en aquellos conectados
directamente a una red de distribución de baja tensión que suministra corriente a edificios
residenciales.

Instrucciones de seguridad elementales
Reparación y mantenimiento
1. El producto solamente debe ser abierto por personal especializado con autorización para ello. Antes
de manipular el producto o abrirlo, es obligatorio desconectarlo de la tensión de alimentación, para
evitar toda posibilidad de choque eléctrico.
2. El ajuste, el cambio de partes, el mantenimiento y la reparación deberán ser efectuadas solamente
por electricistas autorizados por Rohde & Schwarz. Si se reponen partes con importancia para los
aspectos de seguridad (p. ej. el enchufe, los transformadores o los fusibles), solamente podrán ser
sustituidos por partes originales. Después de cada cambio de partes relevantes para la seguridad
deberá realizarse un control de seguridad (control a primera vista, control del conductor de
protección, medición de resistencia de aislamiento, medición de la corriente de fuga, control de
funcionamiento). Con esto queda garantizada la seguridad del producto.
Baterías y acumuladores o celdas
Si no se siguen (o se siguen de modo insuficiente) las indicaciones en cuanto a las baterías y
acumuladores o celdas, pueden producirse explosiones, incendios y/o lesiones graves con posible
consecuencia de muerte. El manejo de baterías y acumuladores con electrolitos alcalinos (p. ej. celdas de
litio) debe seguir el estándar EN 62133.
1. No deben desmontarse, abrirse ni triturarse las celdas.
2. Las celdas o baterías no deben someterse a calor ni fuego. Debe evitarse el almacenamiento a la luz
directa del sol. Las celdas y baterías deben mantenerse limpias y secas. Limpiar las conexiones
sucias con un paño seco y limpio.
3. Las celdas o baterías no deben cortocircuitarse. Es peligroso almacenar las celdas o baterías en
estuches o cajones en cuyo interior puedan cortocircuitarse por contacto recíproco o por contacto con
otros materiales conductores. No deben extraerse las celdas o baterías de sus embalajes originales
hasta el momento en que vayan a utilizarse.
4. Las celdas o baterías no deben someterse a impactos mecánicos fuertes indebidos.
5. En caso de falta de estanqueidad de una celda, el líquido vertido no debe entrar en contacto con la
piel ni los ojos. Si se produce contacto, lavar con agua abundante la zona afectada y avisar a un
médico.
6. En caso de cambio o recarga inadecuados, las celdas o baterías que contienen electrolitos alcalinos
(p. ej. las celdas de litio) pueden explotar. Para garantizar la seguridad del producto, las celdas o
baterías solo deben ser sustituidas por el tipo Rohde & Schwarz correspondiente (ver lista de
recambios).
7. Las baterías y celdas deben reciclarse y no deben tirarse a la basura doméstica. Las baterías o
acumuladores que contienen plomo, mercurio o cadmio deben tratarse como residuos especiales.
Respete en esta relación las normas nacionales de eliminación y reciclaje.
Transporte
1. El producto puede tener un peso elevado. Por eso es necesario desplazarlo o transportarlo con
precaución y, si es necesario, usando un sistema de elevación adecuado (p. ej. una carretilla
elevadora), a fin de evitar lesiones en la espalda u otros daños personales.
1171.0000.42 - 08 Page 13
Instrucciones de seguridad elementales
2. Las asas instaladas en los productos sirven solamente de ayuda para el transporte del producto por
personas. Por eso no está permitido utilizar las asas para la sujeción en o sobre medios de transporte
como p. ej. grúas, carretillas elevadoras de horquilla, carros etc. Es responsabilidad suya fijar los
productos de manera segura a los medios de transporte o elevación. Para evitar daños personales o
daños en el producto, siga las instrucciones de seguridad del fabricante del medio de transporte o
elevación utilizado.
3. Si se utiliza el producto dentro de un vehículo, recae de manera exclusiva en el conductor la
responsabilidad de conducir el vehículo de manera segura y adecuada. El fabricante no asumirá
ninguna responsabilidad por accidentes o colisiones. No utilice nunca el producto dentro de un
vehículo en movimiento si esto pudiera distraer al conductor. Asegure el producto dentro del vehículo
debidamente para evitar, en caso de un accidente, lesiones u otra clase de daños.
Eliminación/protección del medio ambiente
1. Los dispositivos marcados contienen una batería o un acumulador que no se debe desechar con los
residuos domésticos sin clasificar, sino que debe ser recogido por separado. La eliminación se debe
efectuar exclusivamente a través de un punto de recogida apropiado o del servicio de atención al
cliente de Rohde & Schwarz.
2. Los dispositivos eléctricos usados no se deben desechar con los residuos domésticos sin clasificar,
sino que deben ser recogidos por separado.
Rohde & Schwarz GmbH & Co.KG ha elaborado un concepto de eliminación de residuos y asume
plenamente los deberes de recogida y eliminación para los fabricantes dentro de la UE. Para
desechar el producto de manera respetuosa con el medio ambiente, diríjase a su servicio de atención
al cliente de Rohde & Schwarz.
3. Si se trabaja de manera mecánica y/o térmica cualquier producto o componente más allá del
funcionamiento previsto, pueden liberarse sustancias peligrosas (polvos con contenido de metales
pesados como p. ej. plomo, berilio o níquel). Por eso el producto solo debe ser desmontado por
personal especializado con formación adecuada. Un desmontaje inadecuado puede ocasionar daños
para la salud. Se deben tener en cuenta las directivas nacionales referentes a la eliminación de
residuos.
4. En caso de que durante el trato del producto se formen sustancias peligrosas o combustibles que
deban tratarse como residuos especiales (p. ej. refrigerantes o aceites de motor con intervalos de
cambio definidos), deben tenerse en cuenta las indicaciones de seguridad del fabricante de dichas
sustancias y las normas regionales de eliminación de residuos. Tenga en cuenta también en caso
necesario las indicaciones de seguridad especiales contenidas en la documentación del producto. La
eliminación incorrecta de sustancias peligrosas o combustibles puede causar daños a la salud o
daños al medio ambiente.

20.4 MHz IF Output (IF OUT 20.4 MHz)
The 20.4 MHz IF signal of the R&S ESU is provided at the 20.4 MHz OUT female BNC
connector. For resolution bandwidths between 100 kHz and 10 MHz, the bandwidth
corresponds to the selected bandwidth. For bandwidths ≤100 kHz, the bandwidth of the output
is equal to 2.6 * resolution bandwidth, where the minimum value is 2.6 kHz (non-FFT). In the
analyzer mode, the level at the IF output in the case of a signal at the reference level is 0 dBm
if the resolution bandwidth is ≥100 kHz; if the resolution bandwidth is <100 kHz, the level is
-10 dBm (for mixer levels ≥ -60 dBm).
Use suitable double shielded cables.
Video Output (VIDEO OUT)
In analyzer mode, the voltage of the analog detector (video) is output via the BNC connector
VIDEO OUT.
The video signal is unfiltered, i.e. the video bandwidth (VBW) setting on the instrument has no
effect on the video output. The usable video bandwidth is limited only by the set resolution
bandwidth (RBW) to approximately ½ * RBW.
The output voltage is always logarithmic, independent of the selected scaling on the display.
Likewise the selected detectors (e.g. RMS) affect only the display but not the video output. The
output impedance is 50 Ω. All subsequent voltage values are typical values and apply to the
output without load.
With RBW = 100 kHz as well as with all root raised cosine (RRC) and channel filters no video
signal is available.

R&S ESU Preparing for Use
Preparing for Operation
2.1.6 Functional Test
The functional test should only be performed when the operating
temperature is reached (approx. 15 minutes after the instrument is
switched on).
➢ Call self alignment with the CAL key, CAL TOTAL softkey. Once the system correction
values have been calculated successfully, the message Calibration Passed will appear.
➢ Start the self test with the SETUP key, SERVICE – SELFTEST softkeys. Once the
instrument modules have been checked successfully, the message Selftest Passed will
appear.
Once both steps have been completed successfully, the instrument will be ready for operation.
The self alignment does not need to be repeated every time the
instrument is switched on, because the instrument saves the values
and loads them during booting automatically. A self alignment is
recommended if the instrument is used at a temperature that differs
considerable (more than 10°C) from the temperature present at the last
self alignment.
The self test also does not need to be repeated every time the
instrument is switched on. It is necessary only when instrument
malfunction is suspected.

2.3.5 Connecting USB Devices (e.g. a Power Meter)
The USB interface on the front and the rear panel of the R&S ESU allows you to connect up
to 4 USB devices directly to the R&S ESU. This number can be increased as necessary by
inserting 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 ESU. The following list shows various USB devices that can be
useful for the R&S ESU:
• Power sensors of the R&S NRP-Zxx series
(require adapter cable R&S NRP-Z4)
• Memory stick for easy transfer of data to/from a PC
(e.g. firmware updates)
• CD-ROM drives for easy installation of firmware applications
• PC keyboard for entering comments, file names, etc.
• Mouse for easy operation of Windows dialog boxes
• Printer for printing out measurement results
• Modem for remote control of the R&S ESU over large distances
Installing USB devices is easy under Windows, because all USB devices are plug&play. All
USB devices can be connected to or disconnected from the R&S ESU during operation.
After a device is connected to the USB interface of the R&S ESU, Windows 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
R&S ESU before proceeding.
When a USB device is subsequently disconnected from the R&S ESU, Windows immediately
detects the change in hardware configuration and deactivates the corresponding driver.

R&S ESU Preparing for Use
Connecting External Devices
2.3.6 Connecting External Generators
The External Generator Control option (R&S FSP-B10) allows you to operate a number of
commercially available generators as a tracking generator on the R&S ESU. When suitable
generators are used, the R&S ESU thus allows scalar network analysis to be performed also
outside the frequency range of the internal tracking generator. Appendix “External Generator
Control” provides a list of generators supported by the option R&S FSP-B10.
The following figure shows the test setup:
The generator is controlled via the – optional – second GPIB interface of the R&S ESU
(= IEC2, supplied together with the option). With some Rohde & Schwarz generators, it is also
controlled via the TTL synchronization interface that is contained in the AUX CONTROL
interface of the R&S ESU.
• Using the TTL interface allows you to attain significantly higher
speeds than possible with a pure GPIB control, because the
frequency switching mechanism of the R&S ESU is directly coupled
to the frequency switching mechanism of the generator.
• To increase measurement accuracy, use a shared reference
frequency to operate the R&S ESU and the generator. If no
independent 10 MHz reference frequency is available, connect the
reference output of the generator to the reference input of the
R&S ESU and use SETUP – REFERENCE EXT to configure the
R&S ESU to implement the external reference.

2.5 Configuring the LAN Interface
The instrument can be connected to an Ethernet LAN (local area network) using the LAN
interface connector on the rear panel. This makes it possible to transfer data over the network
and to use network printers. In addition, the instrument can be remote-controlled via the
network.
2.5.1 Connecting the Instrument to the Network
Before connecting the instrument to the network, consult your network administrator,
particularly in the case of large LAN installations. Connection errors may affect the entire
network.
Connect a conventional RJ-45 cable (not supplied) to the rear panel of the instrument and a
network hub of the required LAN segment. Since the RJ-45 involves star configuration rather
than bus cabling, no special measures need to be taken.
Setting up the connection does not cause any problems on the network. Likewise,
disconnecting the instrument from the network does not cause any problems as long as no
data traffic to and from the instrument is in progress.

2.5.2.2 Configuring Existing Network Protocols (TCP/IP Protocol)
Before starting, check whether your network a DHCP server. If necessary, ask your network
administrator.
• If your network has a DHCP server, the IP address is to be requested from a DHCP server
automatically. This is the default setting and no change of configuration is necessary.
• If your network has no DHCP server, change the settings according to the following stepby-step instructions. Use IP addresses and subnet masks suitable for your network. If
necessary, contact your network administrator.
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.
➢ Toggle the DHCP On/Off softkey to the required mode.
If DHCP is „Off“, you must enter the IP address manually, as described in the following
steps.
Note: When DHCP is changed from „On“ to „Off“, the previously set IP address and subnet
mask are retrieved.
If DHCP is „On“, the IP address of the DHCP server is obtained automatically. The
configuration is saved, and you are prompted to restart the instrument.
You can skip the remaining steps.
Note: When a DHCP server is used, a new IP address may be assigned each time the
instrument is restarted. This address must first be determined on the instrument itself. Thus,
when using a DHCP server, it is recommended that you use the permanent computer
name, which determines the address via the DNS server.
➢ Press the IP ADDRESS softkey and the IP address, for example 192.0.2.0. The IP address
consists of four number blocks separated by dots. Every block contains 3 numbers in
maximum.
➢ Press the SUBNET MASK softkey and enter the subnet mask, for example 255.255.255.0.
The subnet mask consists of four number blocks separated by dots. Every block contains
3 numbers in maximum.
If you have entered an invalid IP address or subnet mask, the message „out of range“ is
displayed in the status line. The „Edit“ dialog box remains open, and you can start again. If
the settings are correct, the configuration is saved, and you are prompted to restart the
instrument.
➢ Confirm the displayed message („Yes“ button) to restart the instrument.
Using a DNS server to determine the IP address
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.

rights.
The user name is “instrument”. The password of the latest firmware version is “894129”.
The passwords for older firmware version are:
• “123456” (FW4.4x and 4.5x)
• “instrument” (< FW4.4x)
The user name is “instrument” in all firmware versions.
Note that the default password is updated when you upgrade the firmware. However, a
downgrade of the firmware does not restore the previous passwords. Also, a password that
differs from the default one does not change when you upgrade or downgrade the firmware.

2.6 Operating System Properties
The instrument contains the Microsoft Windows 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 instrument 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.
The following program packages have been tested:
The instrument is equipped with the Microsoft Window 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 Microsoft Windows have been
adapted to the instrument. Existing instrument software must always be modified using only
update software released by Rohde & Schwarz.
• Symantec Endpoint Security (virus protection software)
• FileShredder (for reliable deletion of files from the harddisk)
Virus protection
Users must take appropriate steps to protect their instruments from infection. Beside the use
of strong firewall settings and regular scanning of 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 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 “Malware

R&S ESU Basic Measurement Examples
Introduction
5.1 Introduction
This section describes a typical and simple measurement task for an EMI test receiver. Each
operating step is explained with the aid of R&S ESU for rapid familiarization of the user without
the need to know all the details of the operating functions.
In the introductory example a standard measurement of level and frequency is performed with
the aid of the SCAN TABLE. This measurement is an overview and pre-certification
measurement to be performed before the final standard-conformal measurement is carried
out. Each operating step is explained with the aid of R&S ESU for rapid familiarization of the
user without the need to know all the details of the operating functions.
If unknown (RFI) signals are to be measured, it is strongly
recommended to provide for at least 10 dB RF attenuation at the RF
input in order to protect the input circuit.
In the following example, the R&S ESU is set to default values in the receiver mode. The
default setup is activated by pressing first the RECEIVER hotkey and then the PRESET key.
The main default parameters in receiver mode are listed in the following table:
Parameter Setting
Receiver frequency 100 MHz
RF attenuation Auto
Preamplifier Off
Detector AV
Measurement time 100 ms
RES bandwidth 120 kHz
Demodulator Off
Trigger Free run

R&S ESU Basic Measurement Examples
Performing a Level and Frequency Measurement
5.2 Performing a Level and Frequency Measurement
Measurement
Measurement and display of RFI signal levels versus frequency is one of the most frequent
tasks performed by an EMI Test Receiver. In the case of unknown signals, PRESET values
will mostly be used for the measurement. If levels higher than +137 dBµV (10 dB
RF attenuation) are expected or possible, a power attenuator has to be connected in front of
the EMI Test Receiver input. Very high levels may otherwise damage or destroy the attenuator
or input mixer.
Main Test Receiver Functions
The main functions required for the level and frequency measurement are setting the SCAN
TABLE (START FREQUENCY, STOP FREQUENCY, STEPSIZE), selecting the resolution
(IF) bandwidth (RES BW), setting the measurement time (MEAS TIME) and selecting the
detectors (e.g. peak or average) and MARKER functions required for the analysis.
Measurement Sequence - Level and Frequency Measurement
In this example, the spectrum of the signal present at RF INPUT is recorded in the frequency
range 150 kHz to 30 MHz. The SCAN TABLE and associated parameters are manually set.
The example is generally suitable for all fast pre-compliance measurements required for
measuring unknown noise spectra of DUTs in the development stage and for modifying
prototypes and can be used as a basis for final tests later on.
The high speed of fully synthesized scans, the frequency and amplitude accuracy and the
wide dynamic range of the R&S ESU EMI Test Receiver are of utmost importance and very
useful for these measurements.
