1 About this Manual
This manual describes the R&S SR8000 transmitter.
Structure
The transmitter manual, which is the central and overarching part of the total documenta-
tion, describes all the steps involved in installing, starting up, operating and maintaining a
transmitter. At certain places in the transmitter manual reference will be made to the appro-
priate component manuals. Similarly the component manuals will make reference to the
transmitter manual if the component is to be used as a module of the transmitter.
Contents
The manuals in the transmitter family describe all the steps involved in installing, starting
up, operating, maintaining, troubleshooting and servicing the transmitter or a component.
The appendix contains the interface descriptions and the technical documentation.
All manuals are identically formatted for greater clarity. Sections which are not relevant to
a particular manual are included for the sake of form, but left blank.
Safety
All skilled personnel working with a transmitter or its components have a duty to read the
associated manuals and to follow the safety measures described in the Safety section and
at appropriate points in the manual. The transmitter and the individual components of the
transmitter must be used in accordance with the intended use and regulations. All activities
connected with the transmitter or individual transmitter components must be carried out by
skilled personnel. If activities require additional qualifications, this is indicated at the appro-
priate locations in the manual.
Symbols and notation
A "warning triangle" indicates potential hazards. The degree of danger is indicated by dif-
ferent key words next to the warning symbol.
Instructions are presented as numbered steps; the results after the instructions are indent-
ed.
Notes are preceded by the word "Note". They contain additional information and tips intend-
ed to make your work easier.
All other formatting options are intended to improve clarity and are self-explanatory.

2 Safety Instructions for Transmitter Systems
and Equipment
The following points require special attention:
All electrical installation and connection work must be carried out by appropriately skilled
personnel only.
When equipping operating rooms and installing or using electrical equipment, the na-
tional and international safety regulations and recommendations must be observed.
These include, for example:
– Protective measures for the prevention of accidents
– Protection against overvoltages
– Isolation of electrical systems
– Grounding of electrical systems
– Type and laying of electrical lines and cables
– Regulations for special operating rooms and systems.
When installing the transmitter rack the country-specific rules for the prevention of acci-
dents must be observed, for instance with regard to the following:
– Crushing hazard when working beneath suspended loads
– Fall hazards when working on ladders
– Risk of injury when lifting heavy loads.
Personal protective equipment (PPE) must be used when installations or repairs are be-
ing carried out. Depending on the type of work it may be necessary to wear protective
clothing such as hard hats, safety gloves, eye protection, etc.
Instruments and equipment must not be operated unless their cabinets are closed. Ob-
serve the appropriate safety requirements when opening cabinets for service or repair
work.
An external power supply limiter must be used for disconnecting instruments and sys-
tems from the AC supply. In addition, disconnect all external sources of power, i.e. all
measuring cables, extension cables and multipoint connectors (except for special ser-
vice connectors). Then wait a further 5 minutes until all capacitors are properly dis-
charged.
ATTENTION!
The safety regulations specified in this manual must always be complied with.

Chapter 1 Safety
3 General Safety Instructions
This section contains general safety instructions applying to all products manufactured or
sold by Rohde & Schwarz.
In accordance with IEC215 or EN60215, transmitter systems and their add-on equipment
must be operated under the responsibility of qualified technicians only.
All legal provisions must be observed as a prerequisite for operating radio equipment and
systems. The operator or its representative is responsible for compliance with these guide-
lines. In addition they must ensure that the training of the operating staff satisfies the coun-
try-specific requirements. These also include regular training sessions.

5300.9677.72 - 1.7 - EN-4
Chapter 1 Safety
4 Special Hazard Information
4.1 Hazards from AC Supply Voltage
All Vrms > 30 V AC or V > 60 V DC voltages must be regarded as hazardous. When working
on voltages constituting a shock hazard, appropriate steps must be taken to exclude all
forms of risk. Working on live components is strictly forbidden. Work on live components is
only permitted in exceptional circumstances and in full compliance with special safety pre-
cautions.
4.1.1 AC Supply
Ensure that the AC supply specifications for the system or instruments match the spec-
ifications of the local AC supply before connecting the equipment. The supply circuit
must always be protected by a fuse in order to give protection against overload and short
circuit.
Note Obtain the specifications from this documentation and also adhere to the breaking capacity
limits of the fuses and automatic cutouts in the transmitter.
4.1.2 Replacing Fuses
Fuses in parts of instruments that can be accessed by users must only be changed
when disconnected from the power supply. As a matter of principle, replacement fuses
must comply with the specifications on the instrument labeling.
Motor protection switches and automatic line fuses in those parts of a transmitter system
that can be accessed by users must be tripped. If their response range is adjustable, the
ex-factory setting must not be altered. If settings are changed inadvertently, the correct
values shown in this documentation must be set.
4.1.3 Emergency-Off System
Transmitter racks may also be fitted with emergency-off buttons at the customer's re-
quest. These are disabled when the transmitter is delivered. It is the responsibility of the
operator to ensure that the operation of the emergency button complies with safety re-
quirements and that it is included in the emergency shutdown system of the facility. Any
emergency buttons that are not used as previously planned for emergency shutdown
purposes must be removed completely.
Setting up a transmitter in which the emergency-off devices are disabled is not permit-
ted.
The operator is responsible for ensuring that all these circuits are properly integrated
into the emergency-off system on-site. Any circuit that is not included in this scheme
must be labeled accordingly.

5300.9677.72 - 1.8 - EN-4
Chapter 1 Safety
4.1.4 Opening the Transmitter
If the transmitter is to be opened for mechanical and/or electrical work (such as cleaning,
repairs etc) the transmitter must be disconnected from the AC supply. In the case of low
power transmitters this is done by switching off and withdrawing the power plug.
In transmitters that are hardwired to the AC supply, the five basic rules for working on
electrotechnical equipment must be observed without fail:
– Disconnect the transmitter from the power supply
– Secure it against inadvertent switch-on
– Check voltage to ensure that the equipment is de-energized
– Ground or short-circuit the equipment1
– Place a cover on all adjacent live circuits.
Disconnecting transmitter systems from the power supply
Check the present status of all circuits in a transmitter system. Disconnect adjacent cir-
cuits from the AC supply as well, so as to prevent harm if they are touched accidentally.
Also isolate the antenna connector or connect it to a dummy antenna. Otherwise RF en-
ergy could inadvertently be fed back from other operating transmitters in a transmitter
system via RF switches or RF combiners while work is in progress.
It is absolutely forbidden to open a transmitter that has not been isolated from the AC
supply without having taken proper steps to prevent accidental contact with live electri-
cal circuits.
Because of the risks associated with touching live components, it is forbidden to operate
the equipment with its doors open, or when front panels or plug-in modules have been
removed, etc.
While the transmitter is being operated live for the purpose of internal measurements or
repairs, the workplace must be labeled to show a warning about the imminent risks in
accordance with the basic rules of electrical engineering.
Take suitable precautions to prevent unauthorized access to the area.
When the work has been completed, the transmitter must be closed and the manufac-
turer's safety measures relating to the protection against accidental contact must be re-
stored. The functionality of protective devices (e.g. interlocks) must be checked
immediately.
4.2 Hazards from High Energy Circuits
The equipment includes low-voltage circuits that may be fed from a power supply having
extremely low impedance (e.g. amplifier operating voltages). These circuits carry danger-
ously high levels of energy. At Rohde & Schwarz we treat these circuits as constituting a
shock hazard. For safety reasons therefore, there are no accessible high energy circuits in
the user area of the transmitter.
If the cabinet of an operating transmitter is opened, there is a risk of short-circuiting both
voltage terminals of a low-impedance, extra-low voltage circuit. The short circuit gives rise
to an electric arc which can cause burns, flash burns to the eyes (snow blindness) and fur-
ther injuries due to the reaction of the affected person to shock.
1 Transmitters have no built-in grounding or short-circuit switches. Equally safe and reliable steps must be taken
at the technician's discretion.

5300.9677.72 - 1.9 - EN-4
Chapter 1 Safety
Note Instances occurring in practice continue to show that a short circuit triggered by a metal
hand tool causes severe burns. A short circuit causes an arc and the rated output of the
power supply sets up continuous welding.
Exercise the same amount of caution for measurements on low impedance supplies;
e.g. for repair purposes or to optimize the power consumption of the transmitter, as you
would when performing measurements on supply voltages constituting a shock hazard.
If necessary the appropriate protective equipment will have to be installed.
Before opening a transmitter or removing a cover, switch off the energizing voltage and
wait a further 5 minutes until all capacitors are properly discharged.
Do not discharge capacitors by short-circuiting them.
4.3 Hazards from RF Radiation
4.3.1 Obligation to Instruct Personnel
The operator must train all personnel in the operation of this transmitter or equipment in
accordance with EN 60215 and/or IEC 215. It is essential that these regular instruction
sessions emphasize the dangers related to high frequency that exist on the respective
transmitter or equipment. Operators are only authorized to adjust and operate the equip-
ment after successful completion of the respective instruction sessions and after the re-
sults have been placed on record.
High-energy RF circuits inside the transmitter or equipment are routed via conventional re-
movable RF connectors (e.g. type N). Depending on the output power of the transmitter,
the output ports of the equipment are equipped with screw-type or plug-in RF lines or ducts.
Where an RF cable or module carries high power, the connection point or the entire module
is tagged with the general danger warning label (yellow triangle with a black exclamation
mark).
4.3.2 Antenna Connector
If the output power is low, the antenna connector is provided with an appropriately low-pow-
er connector, e.g. "N". It is possible for the antenna connector to be confused with other
signal I/Os that use connectors of the same type.
For the safety of the user it is therefore important not to open the antenna connector while
the transmitter is operating. There is a very real danger of injury from a RF electric arc.
4.3.3 RF Shielding
Life threatening field strengths exist in the interior of cables and modules that conduct RF.
RF cables must therefore never be disconnected when the equipment is operational and
modules must never be operated when they have been opened.

5300.9677.72 - 1.10 - EN-4
Chapter 1 Safety
Transmitters and instruments supplied by Rohde & Schwarz are shielded so that even in
the immediate vicinity there is no danger from RF radiation when all RF lines are connected.
The field strengths comply with the specifications contained in EU directive 1999/519/EC
and the 26th ordinance to the German Federal Government's Emission Control Act of De-
cember 16, 1996 (26. BImSchV), Emission limit values for electrical and magnetic field
strengths of high frequency installations.
These low levels of field strength can only be guaranteed if all RF cables have been con-
nected and modules have been closed.
4.3.4 Rules of Conduct for Transmitter Operation
Disconnecting RF cables that are operational can result in arcs. These may cause burns
and snow blindness. 1
The transmitter system can only be operated when an operating or dummy antenna is
connected.
Do not disconnect any RF cables when the transmitter is operational.
Never operate the transmitter when RF cables have been disconnected.
The antenna feedpoint must also be disconnected when the transmitter is being discon-
nected. Please note that the antenna cable can feed energy from operational transmit-
ters that are connected to the same antenna via an RF diplexer.
Do not open any modules while the transmitter is operational.
4.3.5 Rules of Conduct for Working on Open Transmitters
Dangerous levels of RF will be radiated if a transmitter is turned on after it has been opened
and covers and shielding with general warning labels have been removed from RF mod-
ules.
It is the responsibility of the operator to ensure that proper safety procedures related to the
presence of personnel and work on a transmitter that has been opened be strictly followed.
The necessary safety regulations include:
Display RF radiation hazard signs at the workplace
Wear RF protective clothing
Take special precautions for persons with metal implants, pacemakers, etc, who are
particularly at risk.
4.4 Risk of Lightning Strike
The antenna system must be suitably designed to prevent hazards due to lightning strike.
1 Any attempt to operate the transmitter results in the emission of RF power. The disconnection of RF cables
will turn the RF produced by the transmitter off. Any such attempt to transmit RF can bring about the risk of
injury mentioned above, even if, as in the case of Rohde & Schwarz transmitters, technical measures are tak-
en to limit the seepage of RF to <60 s.

5300.9677.72 - 1.11 - EN-4
Chapter 1 Safety
The transmitters themselves must be operated in lightning protection zone III areas only
(i.e. inside closed, lightning protected buildings).
The antenna output is protected against overvoltage not exceeding 2 kV. Customers must
ensure that the lightning protection fitted to their antenna systems is designed to prevent
over-high voltages reaching the transmitter.
4.5 Fire Risk
Every electrical circuit that is connected to a power supply of sufficient energy constitutes
a potential fire hazard, including radio transmitters. A fire safety concept for radio transmit-
ting equipment must therefore be established.
Operators must be trained in firefighting measures required for electrical installations and
this training must be repeated regularly. Training should satisfy the requirements of VDE
0132 and should be performed in consultation with the local fire department.
These statements apply to Germany. On-site preventive measures can reduce the danger
of fire to a large extent or prevent the spread of a fire as far as possible.
Prevention and firefighting
When the transmitter is being set up, the operator has to ensure that no flammable ma-
terials are stored in or attached to the area below or above the cable entry point.
Materials used to close openings to adjoining rooms must be flame-retardant.
Always wear the appropriate personal protective equipment (e.g. self-contained breath-
ing apparatus with air bottle), even when flames are small or not evident.
Use only suitable fire extinguishers (e.g. CO2extinguishers) for firefighting.
On the one hand, the need for the use of firefighting protective equipment results from the
fact that every fire produces extremely toxic and unnoticeable carbon monoxide. On the
other hand, the materials contained in the equipment and systems will produce toxic va-
pors, gases and dusts, such as sulfuric acid and hydrogen sulfide, hydrochloric acid, diox-
ins, hydrofluoric acid and beryllium oxide dust, when exposed to external flame and heat.
This relates to the following materials:
– Rubber used in cables, grommets, vibration dampers and equipment feet
– PVC in cables and interconnections
– PUR (foam) in isolators, molded parts, sealing mats and isolating strips
– Teflon in cables, interconnections, insulation and printed boards
– Beryllium oxide ceramics in power transistors
4.6 Hazards from Beryllium Oxide (BeO) Ceramics
Note Equipment and modules with parts containing BeO ceramics must be labeled accordingly.
The following explanations apply:

5300.9677.72 - 1.12 - EN-4
Chapter 1 Safety
Parts containing BeO ceramics do not present adverse health effects if used as directed.
However, improper handling can release BeO dust. BeO dust produces chronic pulmonary
damage (berylliosis) and prolonged inhalation of high doses can cause poisoning with
breathing impairment and subsequent death.
4.6.1 Rules of Conduct for Working with BeO Ceramics
Do not open, mechanically manipulate or destroy parts made from BeO ceramics.
These parts must never be scratched, broken, cut, ground, annealed or sandblasted,
not even under fume extraction hoods.
4.6.2 Identification of Parts Containing BeO Ceramics
Rohde & Schwarz clearly identifies all parts containing BeO ceramics in the electric parts
list, the circuit diagram and the transmitter.
The electric parts list contains the following description:
The following warning appears in the circuit diagram:
In the transmitter, every module that contains parts made from BeO ceramics is identified
by a warning sign and a label:
4.6.3 Measures for Dealing with Breakage and Disposing of Waste
Where breakage, mechanical or electrical destruction has produced BeO dust, the dust
must be collected with a damp cloth and sealed in a plastic bag with all the fragments. Al-
ways wear protective gloves.
Attach the hazard symbol and a label to the bag:
BERYLLIUMOXID / BERYL-
LIUM OXIDE

5300.9677.72 - 1.13 - EN-4
Chapter 1 Safety
Ensure that bags are disposed of in accordance with national waste disposal regulations.
Devices containing BeO ceramics that have been unsoldered must be disposed of in the
same manner. All the manufacturers of parts containing BeO ceramics who are known to
Rohde & Schwarz offer to take back faulty parts without charge.
