Safety Instructions
About this Manual
This manual is part of the documentation for the 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 separate 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 into operation, operate and maintain it. Where applicable, the transmitter 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 required to install the transmitter 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.

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 Vrms > 30 V, suitable measures (e.g. appropriate
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).

Special Danger Warnings
4.1
Hazards due to AC Supply Voltage
Safety Instructions
There is a risk of electric shock with any Vrms > 30 V AC or V > 60 V DC voltage. Appropriate 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.1
– Ensure that phase rotation is correct (direction of rotation of fans!).
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 that they have only a limited power output. The
connector is not suitable for supplying power to heating equipment or large test sets.
 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 main transmitter, the trans-
mitter operator is responsible for taking appropriate measures to ensure that the installation is safe in the respective switching state.
2098.1190.72
Obtain the specifications from this documentation and also adhere to the breaking capacity limits of the fuses
and circuit breakers in the transmitter.
- 1.4 -
E-4
Chapter 1
4.1.2
Safety Instructions
Replacing Fuses
 Replace the safety fuses accessible in the operator area only if no voltage is being 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 emergency keys. When the
transmitters are supplied, these keys have basically no function. The transmitter operator is responsible for ensuring that 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 it2
– Cover adjacent active circuits.
 Extremely important! A transmitter normally has several AC supply 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.
2098.1190.72
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.
- 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 antenna
via RF filters, energy from them can be fed back via the antenna cable.
 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 transmitter 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-voltage 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
Chapter 1
Safety Instructions
quency hazards of the individual transmitter or instrument. Only after such training has
been provided and documented may the operating personnel handle switching and operating tasks.
High-energy RF circuits within the transmitter or the instrument are routed via conventional
detachable RF connectors (e.g. N). Depending on the output power, 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:
The 26th ordinance for the Federal Emission Protection Law dated 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. 3
 When disconnecting a transmitter, always disconnect the antenna connector as well. If
other transmitters, etc, are in operation that are coupled to the same antenna 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 transmitter that is switched
on.
Necessary safety regulations include:
2098.1190.72
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.
- 1.7 -
E-4
Chapter 1
Safety Instructions
 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.
Prevention and fire-fighting
 When setting up the transmitter, the operator must ensure that no inflammable materials
are located below or above the cable entry nor attached to it.
Make sure that openings to adjacent spaces are closed in a flame-retardant 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. CO2 extinguishers) may be used.
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, vibration 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

Design and Characteristics
Design and Function
The new air-cooled R&S NV8300 transmitter family is designed for transmitting digital TV
signals in the IV and V frequency bands (UHF). Digital standards 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.

Chapter 2
Design and Characteristics
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 range 470 MHz to 862 MHz.
1.5.2
Amplifier
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 forward 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.

Directional Couplers
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 and 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 as a forward or reflected
power test point.
The P14D rectifier is used in the digital TV transmitter only in combination with the ADE option.
Note

Installation
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/m2.
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.
3.1.2
Preparing Floor Openings (only if Feed and Return pass
through Floor)
If the intention is to connect cables (RF cable, control lines etc.) or intake air/exhaust air
feeds from below, the appropriate floor openings need to be made in the operational building.

Ventilation System
Note
The ventilation system is already installed and wired inside the transmitter.
4.1
Connecting Air Intake/Exhaust Ducts
Installation
The intake and exhaust air outlets are located either on the top or bottom of the transmitter
rack, depending on your order specifications. The "Intake 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 m2/min).
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 become overheated.
The following drawings show the dimensioning on the top and base of the transmitter required for properly connecting the transmitter to the station.

Amplifiers
When the transmitter is delivered, one or two exciters and an R&S NetCCU800 are already
mounted in the rack. The amplifiers, however, are not and must be retrofitted in the rack.
6.1
Installing Amplifiers
WARNING!
Always make sure that the power supply is disconnected before commencing any installation work on the transmitter rack. This will prevent injury caused by electric shock and
damage to the instruments.
CAUTION!
Always have a second person assist you in installing the amplifiers as the instruments are
very heavy (approx. 28 kg).
Note
Before installing the amplifier, make sure that the ventilation covers on the amplifier slots
provided in the frame are open on both sides. Remove the covers if necessary.
Note
It is advisable to install the amplifiers in sequence starting at the top and working down to
the bottom.
Install the amplifiers as follows:
1. Carefully remove the amplifier from its packaging.
2. Select the installation position provided for the amplifier in the transmitter rack.
3. Place the amplifier on the guide rails and slide it carefully into the rack as far as it will go.
The amplifier is guided onto the connections by means of guide pins on the rear panel.
4. Secure the amplifier in place using the 4 screws of the two front brackets on the rack.
5. To install additional amplifiers, repeat steps 1 to 4.

Installation
Connecting Antenna/Dummy Antenna to RF
Connector
The connection flanges for the antenna cables are uniformly 1 5/8“ EIA for TV transmitters
in the R&S NV8300 family. These flanges are located on the roof of the transmitter. Depending on the transmitter station (one or more transmitters), either the antenna (RF cable or RF
transmission line) or an RF connection is connected directly to a multiple combining filter.
ATTENTION!
You should not connect the antenna until you have completed all measurements.
7.1
Connecting Antenna
Connect the antenna as follows:
 Using the 4 screws (M8, 35 mm), secure the coaxial cable preassembled on the station
to the EIA flange of the transmitter's RF output. To prevent the screw connection from
loosening, insert a plain washer and a spring-lock washer.
Note

7.2
Connecting Dummy Antenna
The dummy antenna is only connected when putting the system into operation or for maintenance and repair purposes.
With some dummy antennas that have coolant monitoring and overtemperature monitoring,
the monitoring equipment can be connected to the transmitter. The main protection loop
(X41.1 and X41.2 in the power distribution) can be used here as a temporary measure (e.g.
while the unit is being put into operation).
1. To connect the main protection loop, use the inserted jumper plug and remove the jumper.
2. Connect the monitoring cable in place of the jumper.
If you are using an RF patch panel that allows you to switch between the antenna and dummy antenna by means of an RF U-link connector (permanent installation), you should connect the dummy antenna monitoring unit to the standby protection loop (X41.3 and X41.4
in the power distribution). This requires the patch panel messages to be additionally connected to the R&S NetCCU800 transmitter control unit (X12.15 antenna message or X12.3
dummy antenna message, to X12.16 GND). Activation of the dummy antenna (via X33 in
the power distribution) is then also active.

Used to set the local time
The local time is the time of day or zone time applicable at the station.
Unlike universal time (UTC = universal time coordinated), there is a positive offset for time zones east of Greenwich or a negative offset for time
zones west of Greenwich.This offset is determined by the time zone and
is always a multiple of a full hour or sometimes of a half hour.
In some countries, the clock is set forward by 1 hour in summer (daylight

Adjusting Amplifier Order Numbers to Installation
Positions in Rack
After the transmitter system has been put into operation, entries for the amplifiers (of a particular rack) are displayed in the menu path for the output stage with consecutive numbering
(Amplifier 1 to max. Amplifier 10). Since the numbering is derived from the chronological
sequence in which the amplifiers can be detected on the CAN bus, it does not always correspond to the sequence in which the amplifiers are physically arranged from top (= 1) to
bottom (= n) in the rack.
To make association between menu and amplifier easier, the entries can be sorted.
1. Select Outputstage A > Setup > Rack Setup > Rack 1 > Amplifier Order.
The Amplifier Order window opens.

Precorrection
This section describes the non-linear precorrection sequence in manual mode.
4.1
Functions of Nonlinear Precorrector
4.1.1
General
In the basic version, the graphical user interface of the non-linear precorrector for DTV and
video signals consists of the Nonlinear control panel and the FreqCorrection control panel. In the case of ATV split, two further control panels are provided: Dynamic Control for
the video precorrector and Nonlinear Audio for the audio signal. In combined mode an audio phase precorrector is also provided for audio.
4.1.2
Linear Basic Precorrection
The basic functions of the non-linear precorrector can be accessed via the Nonlinear and
Nonlinear Audio control panels. Additional functions can be performed in the other control
panels.
Every non-linear precorrector consists of an amplitude precorrector and a phase precorrector, each independently affecting the phase distortion and amplitude distortion of the same
signal. The setting of the characteristic is displayed in a graphic in which the X axis represents the instantaneous signal amplitude. The figures 0% and 100% stand for no signal amplitude and maximum amplitude respectively. The Y axis represent the effect and is scaled
to ±50 % for amplitude precorrection and ±45° for phase precorrection. 50% means that at
100% amplitude the level is increased by 3 dB.
Every precorrector has a series of frequency reference points which are used to model the
characteristic. Frequency reference points can be user-defined, shifted in the X and Y directions, be given a fixed or free slope and be deleted. In the X direction a frequency reference point can only be shifted between the two adjacent reference points. The connections
between frequency reference points are computed by means of spline functions.
Every characteristic consists of at least two points, one of which must be at 0% and the other at 100%.
In the case of amplitude precorrection the first point is at [0%, 0%] and cannot be shifted.
The second point is at 100% and can be shifted without restriction in the Y direction. A rising
or falling straight line between the two points represents only an amplification or attenuation
of the signal and does not create non-linear products.
In the case of phase precorrection the first point is at 0% and the second point is at 100%.
Both points can be shifted without restriction in the Y direction. A straight line parallel to the
amplitude axis creates only a signal phase shift and does not create non-linear products.

Nonlinear Frequency Responses
As an additional function, the non-linear components of the DTV/video precorrection (amplitude or phase precorrection) can be assigned a frequency response in the FreqCorrection control panel, and the effect of the frequency response depends on the modulation.
If the amplitude precorrection or phase precorrection is affected by an amplitude frequency
response, only the "individual" precorrection is affected. Amplitude precorrection and phase
precorrection have no influence on one another.
If the amplitude precorrection or phase precorrection is affected by a phase frequency response, part of the "individual" precorrection affects the other precorrection. The amplitude
precorrection and phase precorrection therefore have an influence on one another.
4.1.4
Dynamic Precorrection (ATV Split Only)
In ATV split systems, the large fluctuations in the average value of the video signal brings
about temperature changes in the output-stage transistor which lead to changes in the output stage characteristic as a function of the average value of the modulation. This error can
be compensated for by dynamically modifying the characteristic as a function of the average signal value.
4.1.5
Audio Phase Precorrection (ATV Combined Only)
In ATV combined systems, the common amplification of video and audio causes the audio
signal to be affected by the video signal. This effect can be minimized with the aid of an
audio phase precorrector.
4.2
General Information on Operating Precorrector
The precorrector is operated by means of a web browser. The R&S NetCCU800 or exciter
provides a JAVA applet which is launched by the web browser. This applet contains all of
the elements needed to operate the precorrector.
Note
Detailed information on operating the precorrector and configuring the graphical user interface can be found in the chapter "Operation" of the exciter manual.
4.3
Performing Precorrection
The objective of precorrection is for the precorrector to simulate the non-linear characteristic of the amplifier as accurately as possible in order to increase the linearity of the output
signal.
However, the precorrection limit is tied to the overload capacity of the output stage. To obtain the greatest possible efficiency and lowest possible costs for a given transmitter, the
output stages are set so as to achieve a transmitter output signal of the required quality.

Commissioning
General Requirements
The following requirements should be fulfilled prior to precorrection:
 The transmitter must be operated at its nominal power output and the system level must
be adjusted at all points.
 Precorrection must be on, for which the Nonlinear control panel must be selected in the
precorrector graphical interface. A precorrection curve consisting of a straight line positioned on the X axis must be set for the amplitude precorrection and another for the
phase precorrection.
4.3.2
Determining System Levels
The graphical area contains lines representing distinctive signal levels such as all-white level (Wht), all-black level (Blk) and sync pulse level (Sync), as well as sync pulse level (Sync/
Aud) in the case of ATV combined. In DVT the level lines indicate the peak level (Peak) and
the average value (Avh). These marks indicate maximum level; the actual level may be different.
Changes to the set curve that affect only the range above the system level have no effect
on the signal or on precorrection of the signal.
The following method can be used to determine the actual values:
1. Use two interpolation points to determine the ends of the effective dynamic range in order to define the possible setting range of the precorrector:
a) Add two interpolation points to the amplitude precorrection graph in the area above
the highest mark and set their slope.
You now have four points, consecutively numbered 1 to 4 from left to right. Points 2
and 3 are each indicated by an arrow.
b) Shift points 3 and 4 in the positive Y direction by +50%. Point 3 should then be immediately adjacent to point 2.
c) Use the Write button to write this curve to the precorrector.
2. Now use the Navigator window to reduce the position of interpolation points 2 and 3 together in steps of one percent. Observe the effect:
ATV Split
In ATV split systems, the first effect is seen in the sync pulse length, which
can be clearly observed on the TV demodulator (sync pulse length display) or the TV analyzer.
ATV Combined
In ATV combined systems, the first effect is seen in the intermodulation
products about the two sound carriers fTx ± default f(T2-T1)
DTV
In DTV systems the effect is seen as a reduced shoulder distance
The upper of the two interpolation points thus represents the determined dynamic range limit.
3. Restore the original status.

4.3.3.1
Starting Precorrection
Requirements
The following requirements should be fulfilled prior to precorrection:
 The transmitter must be operated at its nominal power output and the system level must
be adjusted at all points.
 A spectrum analyzer must be connected to the transmitter output.
Note
A measurement should be taken upstream of the output filter as the shoulders are difficult
to detect owing to the band limiting of the filter. When measuring signals using the spectrum
analyzer, it is important to ensure that the precorrection target (e.g. 38 dB shoulder distance) is well above the noise limit, but the frequency range of the spectrum analyzer is
such that no intermodulation is generated in its input section.
 Precorrection must be activated. In the graphics area for the amplitude and phase pre-
correction, two interpolation points are present in each graph: the first point is modulation 0% with magnitude 0% or 0°, and the second point is modulation 100% with
magnitude 0% or 0°.
A DTV spectrum with clear shoulders should be visible on the analyzer.

Start
1. Start precorrection with the phase precorrection.
2. Since phase precorrection and amplitude precorrection affect one another, repeat both
precorrection procedures if necessary until the optimum result is obtained.
4.3.3.2
Phase Precorrection
Proceed as follows for phase precorrection:
1. Add in a phase reference point at about 10%.
This position corresponds to a lower modulation of the amplifier.
2. Shift the magnitude of the interpolation point for 100% up or down in steps of 0.5 or
smaller (+ or -) until the shoulder distance on the analyzer visibly improves.
3. Keep improving the shoulder distance on the analyzer until the optimum result is obtained.
4. Set another point at about 35%.
5. Shift the magnitude of the interpolation point for 10% up or down in steps of ±0.5 or
smaller until the shoulder distance on the analyzer visibly improves.
6. Keep shifting the magnitudes of interpolation points 2 (10%), 3 (35%) and 4 (100%) in
small steps until the optimum result is obtained.
Note
Further interpolation points can be added for an optimum precorrection. The recommended
number is four to a maximum of six interpolation points (including the interpolation points at
0% and 100%).
If phase precorrection gives no improvement or only a minor one, the phase precorrection
must be canceled and amplitude precorrection must be carried out first.

Amplitude Precorrection
The procedure for amplitude precorrection is the same as that for phase precorrection.
If the first interpolation point brings about an improvement, deal similarly with the other interpolation points.
1. Set the interpolation points more or less at the positions of the phase values.
2. Set all magnitudes to zero.
3. Starting with the interpolation point for the white level (low), change the magnitude (in
steps of ± 0.5 or smaller) in order to find the precorrection.
Note

From here on it is a prerequisite that the precorrection for phase and amplitude has been
optimized at all interpolation points.

4. Optimize the shoulder distance using all interpolation points again, in particular by shifting the interpolation point at 100%.
Keep carrying out phase precorrection and amplitude precorrection alternately until no further improvement can be obtained.
Note
Further interpolation points can be added for an optimum precorrection. The recommended
number is four to a maximum of six interpolation points (including the interpolation points at
0% and 100%).
4.3.3.4
Frequency-Dependent Precorrection
Background
The FreqCorrection control panel can be used to influence the characteristic by means of
an amplitude and/or phase frequency response, the effect of which is dependent on the level.
A set frequency response is applied to all signal components having a level greater than
the selected threshold. On the other hand lesser signal components are unaffected.
An amplitude frequency response (Amplitude Slope Amplitude 1/2 or Amplitude Slope
Phase 1/2) and a phase frequency response (Phase Slope Amplitude 1/2 or Phase Slope
Phase 1/2) can be applied to the amplitude characteristic and the phase characteristic independently of one another. Two independent thresholds are available (Position Point 1
or Position Point 2). The position of the thresholds (1 or 2) and their effect (A or P) are
symbolically represented in the graphic.

Optimizing the shoulder distance
1. First use the the Curve Data Amplitude Read and Curve Data Phase Read buttons in
the Nonlinear control panel to read off the characteristics currently set in the precorrector.
The characteristics are displayed in the display part of the graphic.
2. Go to the FreqCorrection control panel.
The characteristics can be seen in the graphic.
3. In the precorrector graphical user interface, switch Correction to ON and also activate
Correction Point 1, Amplitude Slope Point 1 and Phase Slope Point 1. Set Position
Point 1 to 5%.

4. Now minimize the shoulder distance to left and right of the signal range by alternately
setting the amplitude and phase regulators with the aid of the slopes of point 1.
5. Go back to the Nonlinear control panel.
6. If necessary optimize the characteristic.
7. Keep repeating steps 2, 3, 4 and 6 until the shoulder distance to left and right of the signal range reaches the required value between 37 dB and 40 dB.
If necessary you must to some extent suppress the frequency dependent non-linearity in
the upper level range.

4.3.3.5
Fine Adjustment Using an Existing or Preset Characteristic
If the required data is not or is no longer observed to be in an existing or factory-set precorrection characteristic, the precorrection does not necessarily have to be readjusted.
An adjustment to the true amplifier characteristic can be obtained by changing individual
interpolation points. The range with the greatest effect can be determined by slightly changing individual interpolation points. Changing the interpolation values in this range will most
probably produce the desired result. Changes should be made in small steps, preferably
with the aid of the Navigator window. A change must be undone if it does not result in an
improvement.
