1 About this Manual

This manual is part of the documentation for th e NX8000 family of transmitters from Rohde
& Schwarz. Each transmitter and each transmitter component is described in a separate
manual. The individual manuals of the family of transmitters are modular in structure and
complement each other.

Structure

Each transmitter component is described in a sep arate manual and can thus be used as an
individual component (where practical). The transmitter manual is the main document for
the entire set of documentation. It describes all steps that are necessary to install a trans­mitter, put it in to operation, operate and maint ain it. Where a pplicable, the tr ansmitter man­ual refers to the individual manuals for the various components. The component manuals,
in turn, also refer to the transmitter manual whenever the component is to be used as a
transmitter module.

Contents

The manuals for the family of transmitters describe all steps requ ired to install the tr ansmit­ter or one of its components, put them into operation, operate and maintain them, trouble­shoot and service them. The Annex includes interface descriptions plus technical
documents.

For convenience, all manuals are structured identically . Sections that are not relevant to the
manual at hand are also included but are left blank.

Safety

All skilled personnel working with a transmitter or its components must read all relevant
manuals and comply with the safety measures that are d eta iled in the chap ter about safety
and in the applicable sections in the manual. The transmitter and the individual transmitter
components must be used only for their intended purpose. All operations involving the
transmitter or individual transmitter components must be performed by skilled personnel.
The manual will point out specifically if additional qualifications are required.

Symbols and Layout

The triangular warning symbol indicates danger. In addition to the triangular warning sym­bol, different key words indicate the level of pote ntial danger.

Instructions are given in numbered steps or indicated by an "index finger" symbol to the lef t
of the instruction text. The results of the performed instructions are indented.

The key word "Note" precedes notes. Notes contain additional information and tips to help
facilitate the work at hand.

All other formatting options add structure to the text and are self-explanatory.

2 Safety Instructions for Transmitter Systems

and Instruments

ATTENTION!

The safety instructions provided in this manual must be complied with!

Pay special attention to the following points:

 Only skilled personnel may perform electrical installation and electrical connection

tasks.

 Always follow the relevant national and international safety rules and regulations when

equipping operating areas and when setting up and operating electrical equipment.
These rules and regulations include for example:
– Protective measures to prevent accidents
– Protective measures to prevent overvoltage
– Insulation status of electrical equipment
– Grounding of electrical equipment
– Physical properties and laying of electric lines and cables
– Regulations applying to industrial premises and areas as well as to special facilities.

 When setting up the rack, observe the country-specific rules for accident pr evention, for

example with regard to:
– Risk of getting crushed when working with loads suspended in the air
– Risk of falling off ladders
– Risk of injury when lifting heavy objects.

 Use your personal protective equipment for installation and repair work, i.e. wear pro-

tective clothing such as helmets, safety gloves and eye protection, depending on the
task at hand.

 Operate the equipment and systems only when the cabinet is closed. If you have to open

the cabinet for maintenance an d re pair wor k, c om p ly w it h th e a p plic ab le saf et y in str uc ­tions.

 If the equipment and systems are removed from the AC power supply, all poles must be

disconnected. Check for and remove any external power supply, i.e. all measuring ca­bles, extension cables, multiple socket outlets (except for special service sockets). W ait
for five minutes to ensure that any and all capacitors are sufficiently discha r ged.

 Additionally with liquid-cooled transmitters:When filling and installing the cooling system

(pump unit and heat-exchanger unit), observe the rules for handling hazardous sub­stances (cooling agents); see section "safet y dat a sheets abo ut hazardous subst ances"
under "EU safety data sheet in accordance with 2001/58/EC Antifrogen".

3 General Safety Instructions

This section contains general safe ty instructio ns that apply to a ll products manufactured or
distributed by Rohde & Schwarz.

In accordance with IEC 215 and EN 60215, transmitters and their auxiliary equipment must
be operated only under the responsibility of skilled personnel. The EN 60215 standard
("Safety requirements for radio transmitting equipment") defines the minimum requirements

Basic Safety Instructions

Electrical safety

If the information on electrical safety is not observed either at all 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 AC 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 an earthing contact and protective earth connection.

3. Intentionally breaking the protective earth connection 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 the product does not have a power switch for disconnection from the AC supply network, the plug of
the connecting cable is regarded as the disconnecting device. In such cases, always ensure that the
power plug is easily reachable and accessible at all times (corresponding to the length of connecting
cable, approx. 2 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, a
disconnecting device must be provided at the system level.

5. Never use the product if the power cable is damaged. Check the power cable on a regular basis to
ensure that it is in proper operating condition. By taking appropriate safety measures and carefully
laying the power cable, you can ensure that the cable will not be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.

6. The product may be operated only from TN/TT supply networks fused 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. 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, fusing, 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 IEC60950-1/EN60950-1 or IEC61010-1/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 PE terminal on site and the
product's PE 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 fused 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.

1171.0000.42-05.00 Page 3

Basic Safety Instructions

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.

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", 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. 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).

Chapter 1 Safety Instructions

4 Special Danger Warnings

4.1 Hazards due to AC Supply Voltage

There is a risk of electric shock with any V
ate measures must be taken to prevent exposure to any danger when working with voltages
that bear the risk of electric shock. Never work on live parts unless specifically required and
only if the special safety precautions are complied with.

4.1.1 AC Power Supply

 Before connecting the AC power supply, it is important to ensure that the power supply

specifications given for the system or instruments match the nominal specifications for
the local power supply network. The power supply circuit must be protected by means
of fuses in order to prevent overloads and short-circuits.

 Miniature modules have neutral conductor fuses. As a result, the power supply may still

be connected even after interruption of the circuit by a fuse.

It is quite possible for a transmitter to have several separate electric circuits. Each of these
circuits is subject to the following requirements:

 All electrical connections between the transmitter and the AC power supply must comply

with the following conditions:
– The transmitter can be disconnected at any time.
– The transmitter can be prevented from being switched back on.
– The transmitter is terminated with a fully protected power cable matched to the power

consumption.

– Ensure that phase rotation is correct (direction of rotation of fans!).

1

> 30 VAC or V > 60 V DC voltage. Appropri-

rms

Service sockets

It is common practice to equip transmitters with a connector that carries voltage even when
the transmitter is turned off and that allows power to be supplied to test equipment or a sol­dering iron. These connectors are identified, e.g. by an LED, and may only be used for the
aforementioned purposes.

The intended purpose of the sockets means th at they have only a limited power output. The

connector is not suitable for supply ing power to heating equipment or large test set s.

 The transmitter operator is responsible for providing the correct fuse protection (the

maximum value is specified on the socket).

 In the case of accessory parts that are not connected to the ma in transmitter, the trans-

mitter operator is responsible for taking appropriate measures to ensure that the instal­lation is safe in the respective switching state.

1 Obtain the specifications from this documentation and also adhere to the breaking capacity limits of the fuses

and circuit breakers in the transmitter.

2098.1190.72 - 1.4 - E-4

Chapter 1 Safety Instructions

4.1.2 Replacing Fuses

 Replace the safety fuses access ible in th e op erator are a on ly if n o voltage is be ing ap-

plied to the instruments. The safety fuses may be replaced only by fuses with identical
electric data, identical switching characteristics and identical switch-off capacity.

 Motor and line circuit breakers accessible in the transmitter's operator area may be op-

erated. If their response range is selectable, do not change the settings made by the
manufacturer. If the settings are accidentally changed, reset them by using the correct
values specified in this documentation.

4.1.3 Emergency-Off Equipment

 If the customer requests, the transmitters are equipped with emerg ency keys. When the

transmitters are supplied, these keys have basically no function. The tr ansmitter opera­tor is responsible for ensuring th at these emergency keys function safely and to inte­grate them into the emergency-off system of the operator area in accordance with the
regulations. If you subsequently decide not to use the emergency keys as an emergen­cy-off system, you must remove them.

 Extremely important! A transmitter normally has several AC supply circuits that are

independent from each other, such as main AC supply circuit, AC current supply for ac­cessory equipment (main control unit, antenna switch, etc) or AC current supply for a
disabled socket.

The transmitter operator is responsible for making sure that all these circuits are inte­grated correctly into the emergency-off system. Circuits not integrated have to be la­beled accordingly.

 Never set up a transmitter that is equipped with disabled emergency-off equipment.

4.1.4 Opening the Transmitter

 When you open the transmitter to carry out mechanical/electrical tasks (e.g. cleaning,

repair, etc) always follow the five basic rules for working with electrical systems:

– Disconnect the transmitter from the power supply
– Secure it against inadvertent switch-on
– Verify safe isolation from any power
– Ground or short-circuit it
– Cover adjacent active circuits.

 Extremely important! A transmitter normally has several AC supp ly circuits that are in-

dependent from each other, such as main AC supply circuit, AC current supply for ac­cessory equipment (main control unit, antenna switch, etc) or AC current supply for a
disabled socket.

Prior to performing any work, check the current status of the circuits. Also disconnect
adjacent circuits to prevent inadvertent contact.

2 Not all transmitter types can be grounded or short-circuited by using a grounding or short-circuit switch. If a

suitable device for grounding or short-circuiting is not available, the skilled personnel must take appropriate
measures as deemed necessary.

2

2098.1190.72 - 1.5 - E-4

Chapter 1 Safety Instructions

 If you have to perform any work on the RF circuit, isolate the antenna connector as well.

Caution! If other transmitters, etc, are in operation that are coupled to the same ante nna
via RF filters, energy from them can be fed back via the antenna cabl e.

 Never open a disconnected transmitter without taking protective measures against

touching voltage-carrying parts.

 Due to the risk of electric shock from the AC supply voltage, never perform any electrical

operations when doors are open, front panels are unscrewed, plug-ins are withdrawn,
etc.

 When electrical operations of the transmitter are performed for the purpose of internal

measurements or repair, label the workplace accordingly and provide warning about the
potential hazards in accordance with the basic rules of electrical engineering.

Appropriate measures have to be taken to prevent unauthorized persons from access­ing this area.

After completing your work, close the transmitte r and restore all safety measures for pre­venting electric shock that have been provided by the manufacturer. Immediately make
sure that protective equipment (e.g. locks) is effective.

4.2 Hazards due to High-Energy Circuits

The instruments include low-voltag e circuits which can be fed from an extremely low-imped­ance voltage source(e.g. amplifier operating voltage). These circuits conduct dangerously
large amounts of energy. We handle these circuits in the same manner as circuits with volt­ages that bear the risk of electric shock. They are usually covered and thus protected
against accidental contact. The cover comes with a warning label.

If you remove the cover of a transmitter that is in operation, there is the risk of both voltage
poles being short-circuited. Short circuits create an electric arc and thus can cause burns,
damage to the eyes as well as further injuries due to the state of shock response.

Practical experience has repeatedly shown that a short circuit caused by metal tools can
cause severe burns. For safety reasons, high-energy circuits are protected by covers and
are thus not accessible within the operator area of the instruments.

 If you need to measure low-impedance voltages, during repair work or to optimize the

power consumption of the transmitter for example, exercise the same caution as when
measuring operating voltages that bear the risk of electric shock.

Wear protective clothing if necessary.

 Before you open an instrument or remove its cover, switch off the operating voltage and

wait for five minutes to ensure that any and all capacitors are sufficiently discharged.

 Do not short-ciruit capacitors to discharge them.

4.3 RF Hazards

4.3.1 Mandatory Training

 Operators must instruct their personnel on how to use this transmitter or instrument in

accordance with EN 60215 and IEC 215. This periodic training must cover the radio-fre-

2098.1190.72 - 1.6 - E-4

quency hazards of the individual tra nsmitter or instrum ent. Only after such training has
been provided and documented may the operating personnel hand le switchin g and op­erating tasks.

High-energy RF circuits within the transmitter or the instr ument are routed via conven tional
detachable RF connectors (e.g. N ). Depending o n the output p ower, the transmitter or in­strument outputs come with screw-in or pluggable RF lines or ducts.

If RF lines or modules conduct high power, the connection point or the entire module is
marked with the standard warning symbol (yellow triangle with black exclamation mark).

4.3.2 RF Shielding

Transmitters and instruments from Rohde & Schwarz are shielded in such a manner that
RF radiation does not pose any danger even in the immediate vicinity if all RF lines are
closed. This statement is based on the ordinance for electromagnetic fields as defined in
German law:

Chapter 1 Safety Instructions

The 26th ordinance for the Federal Emission Protection Law d ated December 16, 1996 de­fines limit values for radio-frequency equipment for electric and magnetic field strengths.

4.3.3 Rules for Operating the Transmitter

Opening RF lines during operation may cause electric arcs. This can cause burns and eye
injuries.

 Operate the transmitter system only if an antenna or dummy antenna is connected.
 Never undo RF lines during transmitter operation.
 Never open modules during transmitter operation.
 Never put transmitters into operation if RF lines are open.
 When disconnecting a transmitter, always disconnect the antenna connector as well. If

3

other transmitters, etc, are in operation that are coup led to the same ante nna via RF fil­ters, energy from them can be fed back via the antenna cable.

4.3.4 Rules for Working with an Open Transmitter

If you switch on an open transmitter and remove covers and shielding that carry the general
warning symbol of RF modules, dangerous RF levels will be radiated .

The transmitter operator is responsible for strict compliance with the necessary safety pre­cautions when someone is working with or located near an open transm itter that is switched
on.

Necessary safety regulations include:

3 If you try to put the transmitter into operation, RF power is transmitted. If RF lines are open, the transmitter

switches off the RF again. This attempt to transmit RF can lead to the above mentioned risks of injury even if

- as is the case with Rohde & Schwarz transmitters - the RF flow is limited and transient due to technical mea­sures.

2098.1190.72 - 1.7 - E-4

 Labeling the workplace as subject to RF hazards
 Wearing RF protective cloth
 Taking special safety precautions for persons with implants such as metal parts, pace-

makers, etc, since they are particularly susceptible to injury.

4.4 Fire Hazards

Every electric circuit containing sufficient energy and to which voltage is applied poses fire
hazards. This also applies to radio transmitters. For transmitter radio systems, it is therefore
necessary to create a safety plan for the event of fire.

Operating personnel must be trained on how to proceed in the case of fire in areas contain­ing electrical systems; training must be repeated at regular intervals. Personnel should be
trained on the basis of the VDE 0132 standard and in agreement with the local fire depart­ment.

The following statement applies in Germany. Preventive measures at the site in question
can largely eliminate the risk of fire or prevent its spread as far as possible.

Chapter 1 Safety Instructions

Prevention and fire-fighting

 When setting up the transmitter, the ope rator must ensure that no inflammable materi als

are located below or above the cable entry nor attached to it.
Make sure that openings to adjacent spaces are closed in a flame-ret ardant manner.

 Fire-fighting is only allowed with special equipment even if the flames are insignificant

or have no effect at all (e.g. breathing mask with air bottle).

 For fire-fighting, only suitable fire extinguishers (e.g. CO

extinguishers) may be used.

2

One reason for requiring special equipment is the fact that extremely poisonous and imper­ceptible carbon monoxide is released during every fire. Another reason is that the materials
contained in the instruments and systems emit poisonous vapors, gases and dust such as
sulfuric acid and hydrogen sulfide, hydrochloric acid, dioxin, hydrofluoric acid and beryllium
oxide dust when they are exposed to external flame and heat.

The following materials can be affected:
– Rubber in cables, cable bushings, vibratio n absorbers and instrument feet

– PVC in cables and lines
– PUR (foam) in insulators, molded parts, sealing mats and insulating strips
– Teflon in cables, lines, insulation material and printed boards
– Beryllium oxide ceramics in power transistors

1 Design and Function

The new air-cooled R&S NV8300 transmitter fam ily is designed for transmitting digital TV
signals in the IV and V frequency bands (UHF). Digital st andards DVB-T/-H, ATSC, DTMB,
ISDB-T and MediaFLO can be transmitted.

LDMOS transistor-based amplifiers ensure high output power while requiring only minimum
space. For ATSC, output power of 500 W to 1.8 kW is available.

Both the power class of the transmitter and its type designation depend on the number of
built-in amplifiers.

Note This section is not relevant for transmitters having only one amplifier in the rack.

Fig. 21 Combiner (1) with splitter (2); here R&S NV8304

2098.0188.72 - 2.17 - E-1

The splitter distributes the output signal of the exciter to the individual amplifiers. In addition,
an integrated attenuator that is dependent on the number of outputs ensures that the RF
signal is output at the right power level.

The splitter is a broadband unit that operates in the frequency ran ge 470 MHz to 862 M Hz.

1.5.2 Amplifier

Chapter 2 Design and Characteristics

Fig. 22 R&S VH8300A1 amplifier

The R&S VH8300A1 air-cooled amplifier operates in the broadband range from 470 MHz
to 862 MHz (UHF bands IV/V) and is suitable for both analog and digital signals without
needing to be adjusted. The output power of an amplifier is, depending on the requirements
with regard to the MER, between 450 W und 500 W.

The amplifiers amplify the exciter signals distributed by the splitter and forwa rd them to the
combiner. The amplifiers in a transmitter rack are controlled via the rack controller. Mea­sured values and status information are recorded by the rack controller via CAN bus and
forwarded to the R&S NetCCU800 transmitter control unit. The number of amplifiers in the
transmitter depends on the transmit power.

Note For detailed information about the amplifier, refer to the amplifier manual.

Transmitters with one amplifier in rack

In transmitters with only one amplifier in the rack, the splitter and combiner are omitted. The
signals of the exciter are fed directly to the amplifier and, following amplification, routed fur­ther downstream in the signal path to the harmonics filter.

1.5.3 Combiner

Note This section is not relevant for transmitters having only one amplifier in the rack.

2098.0188.72 - 2.18 - E-1

Chapter 2 Design and Characteristics

Fig. 23 Combiner (1) with splitter (2); here R&S NV8304

The RF power output from the amplifiers is merged with th e correct phase via the combiner .
The combiner consists of a cascade of 90° hybrids housed in a single unit.

1.5.4 Absorber

Note This section is not relevant for transmitters having only one amplifier in the rack.

2098.0188.72 - 2.19 - E-1

2098.0188.72 - 2.21 - E-1

1.6.2 Directional Couplers

Chapter 2 Design and Characteristics

Fig. 26 Directional couplers

The forward and reflected power is detected at the transmitter output by means of the fre­quency-compensated directional couplers P14A (forward) and P14B (reflected). The fre­quency-compensated directional couplers output a power-proportional DC voltage to the
R&S NetCCU800 transmitter control unit via the integrated rectifier circuit. The DC voltages
for forward and reflected power are displayed in the R&S NetCCU800 an d also used as an
S measurement for VSWR monitoring (reflection on the antenna).

Directional coupler P14C is a free test point that can be used either a s a forward or reflected
power test point.

The P14D rectifier is used in the digital T V transmitter only in combination with the ADE op­tion.

Note The transmitter is switched off due to reflection if the reflected value exceeds 2% of the for-

ward value after being checked three times.

1.7 Harmonics Filter

Fig. 28 Harmonics filter; here R&S NV8304

2098.0188.72 - 2.23 - E-1

Chapter 2 Design and Characteristics

The FH 825 harmonics filter is used to suppress harmonics. It is a 23rd order Chebyshev
filter which uses coaxial technology so that it is suitable for the rigid line system 13-30. On
the signal path, the harmonics filter is located directly downstream of the combiner.

Note The harmonics filter is varnished to reduce the su rface temperature.

Transmitters with one amplifier in rack

In transmitters having only one amplifier in the rack, the harmonics filter is connected direct­ly with the RF output of the amplifier via a coaxial cable.

1.8 RF Connector

Chapter 2 Design and Characteristics

1.9.1 Intake/Exhaust Air Ducts

Fig. 31 Intake air duct (1) and exhaust air duct (2); here R&S NV8304 with option intake air from below

The air from the intake duct is drawn in by the fans and forwarded to the distribution shaft.
The distribution shaft provides enough air to each amplifier to cool it. The heated air is rout­ed to an air collecting shaft on the opposite side of the amplifier and expelled via the ex­haust duct.

Note The intake/exhaust outputs are located either on the top or bottom of the rack, depending

on your order specifications.

2098.0188.72 - 2.26 - E-1

If the intake is at the bottom, there is no intake duct. The connecting flange is then located
directly beneath the fan box.

If the exhaust air is directed downward, the absorber unit is situated at the bottom and feeds
into the exhaust connection.

1.9.2 Fans

Chapter 2 Design and Characteristics

Fig. 32 Fans

A standard transmitter rack contains two fans, which adequately cool the transmitter with
air. If one of the fans is defective, a warning is sent to the controller but the transmitter con­tinues to operate. If both fans fail, the rack controller switches off the affected rack. The
transmitter indicates a cooling malfunction.

Chapter 2 Design and Characteristics

1.9.4 Differential Pressure Gages

Fig. 34 Differential pressure gages

The differential pressure gages (diaphragm switches) measure the differential pressure of
each fan between the fan flange (output) and the envir onment. Thu s, fan malfunctions can
be selectively sent to the transmitter control unit.

2098.0188.72 - 2.29 - E-1

1.9.5 Temperature Sensors

Chapter 2 Design and Characteristics

Fig. 35 Temperature sensors

The temperature sensors measure the absolute intake and exhaust air temperatures in °C
for display on the R&S NetCCU800 and monitoring in the rack controller.

Note If the exhaust temperature exceeds 65 °C, the rack controller switches off the rack due to

the risk of overheating.

Chapter 3 Installation

3 Setting Up Transmitter

Make sure that the transmitter is standing in a stable position and that ventilation is suffi­cient.

Note During installation, the transmitter must be easily accessible from the front and rear. A

clearance space of at least 1.2 m is necessary in order to install all components.

3.1 Preparations

Before setting up and installing the transmitter, you must make the following preparations:

 Check general suitability of location
 Prepare any openings required in the floor
 Set screw holes in floor for fixing the rack (optional)

3.1.1 Checking Structure, Flatness and General Suitability of
Installation Surface

Before installing the transmitter you must check whether the floor of the building in which
the transmitter is to be operated has an adequate weight to floor-area ratio.

The total weight of a transmitter rack can be as much as 385 kg when fully equipped with
plug-in units. This results in a weight to floor-area ratio of at least 800 kg/m

Note The exact weight of your transmitter is given in the specifications.

The installation surface should be flat (i.e. horizontal along all axes) and measure 600 mm
x 800 mm to accommodate the transmitter rack.

Note During installation, the transmitter must be easily accessible from the front and rear. A

clearance space of at least 1.2 m is necessary in order to install all components.

 Check the structure, flatness and general suitability of the chosen installation location.

4 Ventilation System

Note The ventilation system is already installed and wired inside the transmitter.

4.1 Connecting Air Intake/Exhaust Ducts

The intake and exhaust air outlets are locate d either on the top or bottom of the transmitter
rack, depending on your order specifications. The "Int ake air from room" option is also avail­able. In this case, the intake air is routed to the intake box via an integrated air filter on the
rear panel.

The external pressure drop must not exceed 100 Pa for the required air volume (e.g. for
R&S NV8304, 4 amplifiers: 17 m

As a result, a pipe system of max. 12 m in length (D = 250 mm), two 90° bends and an air
filter with a drop in discharge pressure of 40 Pa can be installed.

Note Always use pipes with a diameter of 250 mm.

ATTENTION!

The temperature of the cooling air must not drop below the dew point, otherwise conden­sation may occur in the air shafts.

If intake air is fed in directly from outside the building, an air filter must be used.

Note Be sure to connect the intake and exhaust lines properly, otherwise the system may be-

come overheated.

The following drawings show the dimensioning on the top and base of the transmitter re­quired for properly connecting the transmitter to the station.
