Safety Symbols
Assemblies within the transmitter system that contain high voltage conditions have safety
symbols attached to them.
HIGH VOLTAGE
This symbol identifies the presence of high voltage that can cause injury or death.
3.4
Electrical Shock and the Human Body
Electrical shock or electrocution occurs when the body becomes part of an energized electrical
path and this electrical energy passes through the body.
The body subjected to a difference of potential, or stored electrical charge causing current to
flow through the body, will be shocked or electrocuted. Effects of electrical shock may include
severe burns to the skin and/or internal organs and respiratory or cardiac arrest. Any electrical
current that flows through the central nervous system of the human body has the potential to
cause serious injury or death.
Severity of electrical shock depends upon the source and duration of exposure. Use the
following information in conjunction with a vigilant and on-going safety program. This information
is in general terms and does not include unknown variables that may increase susceptibility to
electrical shock. Always exercise Awareness and Caution.
Direct Current (DC): Low voltage (up to 72 VDC) usually does not present a hazard to human
life, but a severe burn is possible under some conditions. Medium and high voltage (greater
than 72 VDC) can cause severe shocks, burns, and even death.
Alternating Current (AC): At commercial frequencies (50-60 Hz) and intermediate voltages (72
to 600 VAC), lethal current can flow through the body. Even low AC voltages (24 VAC or less)
under certain circumstances can be dangerous and lethal. The danger of shock is less at high
frequencies, but radio-frequency (RF) burns are possible.
Body Resistance: The resistance of the body and the amount of insulation between the body
and electrical earth-ground determine the amount of electrical current that passes through the
body. The skin presents the greatest resistance of the human body to impede current flow.
Please note that skin resistance decreases with increased voltage.
Time of Contact: The length of time the body remains in contact with electrical current
determines the severity of possible injury. Burns break down the skin and thus lowers the body’s
ability to resist electrical current. The more extensive the burn, the less resistance the skin
provides. As current flow increases, so does the severity of the shock. The duration of contact is
critical. Current flowing through the body causes loss of muscle control, chest contractions
(breathing is impaired) and ventricular fibrillation of the heart. During fibrillation, the heart cannot
pump sufficient quantities of blood.
Magnitude: The magnitude of the electrical current determines the extent of muscle-control
loss, effects on the heart, and severity of burns.
Safety
-5-
Affinity® LBD-200C-N1 Transmitter
Product Manual
Path: The path of the electrical current through the body is critical. When current passes from
hand to hand, or hand to foot, the brain, heart, lungs, and spinal cord, which become part of the
electrical path, are affected.
Age and Condition of Victim: The age and physical condition of the victim affects the severity
of electrical shock. Elderly victims, young children, or those with existing medical conditions, are
more susceptible to injury caused by electrical shock.
3.5
Emergency Procedures for Electrical Shock
Anyone engaged in electrical or electronic work should be aware of the proper safeguards and
emergency procedures related to hazardous electrical conditions. An understanding and
knowledgebase regarding electrical hazards will reduce the risks and dangers of electrocution.
Obtaining safety related training courses such as First Aid and CPR, and applying them during
emergencies, might greatly reduce the effects of electrically induced injuries.
Promptly report to the appropriate personnel any electrical “popping” or sparking, and any
noticeable defects or hazardous conditions that can cause injury, property damage, or
interference to the electrical equipment.
Immediately report any electric shock received to the appropriate supervisor or safety
personnel.
In the event that an individual comes into contact with a live electrical circuit:
x Cut off the power. Learn how to remove power anywhere within the work area.
x Free a victim from a live circuit. If a person is “frozen” to a live electrical contact,
turn off the power if possible. If you cannot turn off power, use wooden boards,
poles, sticks, a belt, dry rope, articles of clothing or some other nonconductive
material of sufficient strength to pull the affected person from electrical contact.
x Contact emergency personnel. Immediately contact emergency medical
personnel. Only qualified and trained personnel should perform First Aid
procedures.
WARNING
Under no circumstances touch a victim
exposed to a live circuit. Doing so will place
you in the live circuit, and may result in
injury or death due to electrocution.

Transmitter Electrical Hazards
WARNING
Use appropriate practices when working
near high voltage. The removal of panels
identified with warning symbols can
expose the mains voltages. These
voltages can cause injury or death.
Transmitter Electrical Hazards Warning
The transmitter uses lethal voltages that can cause injury or death. The transmitter assemblies
fully enclose these voltages to prevent accidental contact.
Thales recommends these safe-working practices:
x Operate and maintain the transmitter according to the instruction manuals.
x Do not allow personnel to work alone on the transmitter.
x Permit only skilled personnel to operate the transmitter. See IEC 60215.
x Ensure personnel know the location of circuit breakers and mains disconnect
switches.
x Ensure the transmitter is OFF, disconnected from the AC mains voltage, and
secured via a lock-out/tag-out process before working in any areas identified with
warning symbols.
x Ensure all personnel have training in First Aid and CPR procedures.

Overview
The Thales Broadcast & Multimedia Affinity® is an advanced low power solid-state Coded
Orthogonal Frequency Division Multiplexing (COFDM) Digital Video Broadcast-Terrestrial (DVBT/DVB-H) transmitter. The Affinity® is fully compliant with European Telecommunications
Standards Institute (ETSI) EN 300744 DVB-T, EN 302304 DVB-H specification requirements,
and complies with all FCC requirements. The design goal of the Affinity® family of transmitters
was to allow broadcasters to cost effectively begin broadcasting in DVB-T/DVB-H formats while
accomplishing the following objectives:
x Optimum signal performance in all operating modes
x Maximum redundancy for 100% power output
x Ease of initial setup and operation
x Ease of monitoring and diagnostics
x Flexible solutions for all site layouts and installations
The Affinity® L-Band solid-state low power transmitter is available in several models providing
output powers ranging from 50 to 400 Watts average (rms). The transmitter brand can house up
to sixteen high-gain full-band GaAs FET amplifier modules operating in parallel. The quantity of
amplifiers installed for a system is determined by the desired output power.
Each Affinity® transmitter is provided with a DVB-H RF Sirius Exciter containing linearization
circuits to compensate for both linear and non-linear distortions. The correction can be operated
in an adaptive mode allowing automatic compensation and signal optimization.
The Affinity® family of solid-state low power transmitters includes an advanced control system
providing enhanced monitoring and diagnostic capability. The single or dual drive configuration
determines the operating interface for the system.
For single drive (SD) configurations, the front panel of the DVB-H RF Sirius Exciter includes a
Local Control & Monitoring Panel (LCMP) with a man-machine interface (MMI). The MMI
consists of a front panel Liquid Crystal Display (LCD) and a soft-key activated menu that
provides transmitter controls, power readings and alarm indicators.
For dual drive (DD) operation, each of the DVB-H RF Sirius Exciter units are controlled by an
external Central Processing Unit (CPU) that includes switchover management for a Web server
or SNMP agent. The LCMP for dual drive operation consists of a color touch screen with menus
and bar graph.
Remote operation for both configurations can be made by either an embedded Web server
through a standard browser, or through a SNMP agent by means of an SNMP manager.

Affinity® Low Power Transmitter Configurations
There are three basic transmitter configurations available:
Single Drive – One exciter/driver chain drives the power amplifiers in parallel. This configuration
includes options for N+1 power supply.
Dual Drive – Two exciter/driver(s) operating in a main/standby automatic switching mode drives
the power amplifiers in parallel. This configuration includes options for N+1 power supply.
Diversity Transmitter – This configuration can feed four antennas in 90o sectors. There are two
independent single drive transmit chains fed by a common exciter with embedded time delays
on each output. The exciter time delay function is defined in the DVB-H standard, EN 300744.
The delay must be within the guard interval defined in the network, and should add a few
microseconds of delay in relation to the other transmitter in the site. The timing information can
be sent to the transmitter via the Megaframe Information Protocol (MIP) or can be adjusted
locally in the modulator.
4.3
Affinity® Family Construction
The Affinity® family of low power solid-state DTV transmitters is designed to provide maximum
flexibility for site layout and installation. All of the transmitter chassis are designed to fit in EIA
standard 19” wide equipment cabinets. Outdoor installations are equipped with high quality front
and rear access enclosures. These enclosures maintain security and protection against external
elements. Transmitter systems are available in several configurations based on output power,
redundancy options, and site system requirements.
Single channel, non-redundant transmitter configurations (SD) are sized as follows:
x For 50 to 125 watt average output power levels, the upconverter and amplifier are selfcontained in a single 6 rack unit (RU) chassis. The N+1 capable power supply is housed
in a 3RU chassis, and the Thales DVB- T/H RF exciter is contained in a 2RU chassis.
This 11RU transmitter is the most compact Thales Affinity system.
x For 200 watts average output power levels, three chassis are used (14RU total). The
upconverter assembly is self-contained in a single 3RU chassis. The power amplifiers
are housed in a 6RU chassis. The N+ 1 capable power supply is housed in a 3RU
chassis and the Thales DVB- T/H RF exciter is housed in a 2RU chassis.
x For 400 watts average output power levels, four chassis are used (20RU total). The
upconverter assembly is self-contained in a single 3RU chassis. The power amplifiers
are housed in two 6RU chassis. The N+1 capable power supply is housed in a 3RU
chassis and the Thales DVB- T/H RF exciter is housed in a 2RU chassis.
A dual drive transmitter operating in main/standby configuration (DD) is sized as follows:
The Thales DVB-H RF exciter is contained in a19” 9RU chassis that includes: 2RU chassis for
the DVB-H RF exciters, 3RU chassis that house the CPU board with PSU, the DVB-H RF
Exciter/Up Converter, and the amplifiers interface board. 1RU is used for the fan unit and air
inlet, and 1RU for the dedicated front panel that supports the touch screen and bar graph.

Affinity® LBD-200C-N1 Transmitter
Product Manual
The transmitter uses self-contained ambient forced air-cooling (front to back airflow). All fans
are internal to the chassis. Refer to the Cabinet Air Conditioning section of this manual for
additional details of the LBD-200C-N1 transmitter cooling and environmental control systems.
The transmitter system including all ancillary equipment is housed in a Nema 3R rated
enclosure with approximate dimensions: 74” H x 44” W x 44” D. This self-contained unit features
eyelets for lifting the entire assembly during installation. The base has mounting provisions for
mechanical and electrical attachments to building structures. Equipment access is achieved
through front and rear opening doors fitted with locks and intrusion alarms with remote
signaling. Internal enclosure lights illuminate when any door is opened during maintenance. A
smoke/fire detector with remote signaling is utilized to provide the earliest warning of
catastrophic failure caused by a natural occurrence or other means.
Located inside the enclosure is an EIA standard 19” rail structure system used for rack
mounting each sub system contained in the Affinity® configuration.
The AC distribution system is comprised of: 120/230VAC surge suppression with alarms, two
230VAC outlets, and two 120VAC outlets with separate circuit protection. Four 230VAC utility
outlets are provided along with four UPS protected outlets located along the rear corner of the
enclosure. These outlets are intended to connect transmitter ancillary equipment. An external
disconnect box allows connection of a portable generator. An AC hour-meter will record the
operational hours of the equipment.
A UPS is employed to keep critical subsystems running in instances of temporary AC power
loss. The 230VAC UPS output is capable of 700VA/490W. Storage for the UPS is via two
24VDC extended battery modules capable of providing an output of approximately 210 Watts for
400 Minutes (6.9 Hrs). This power is intentionally distributed to the site management system,
satellite receiver, and DVB-T/H RF exciter to enable status communications from the site, back
to the operations center, to continue while normal operating site power is absent. Having the
exciter and satellite receiver powered up also minimizes transmitter restart times once normal
site power has been restored.

Thermal Protection:
Certain plug-in modules are thermally protected with over-temperature sensors. If temperatures
exceed 122º Fahrenheit (45º Celsius), the plug-in module is shut down by the microprocessor
until the temperature is below the trip-point level.
Interlocks:
Interlocks are performed through the software applications.
VSWR Protection:
The Voltage Standing Wave Ratio (VSWR) protection system will lower the transmitter output
power by 6dB if the reflected power exceeds 16%, of the transmitter output power (calibrated on
a 100% scale). If the reflected power reaches 25% of the transmitter output power, the VSWR
protection system shuts the transmitter down. To bring the transmitter back into operation after
a VSWR protection shutdown requires an operator to perform a transmitter reset through the
Omnitronix SL-81 Site Management system, local reset via MMI on front panel, or by cycling the
Upconverter Module power.

Equipment Packaging
The transmitter is packaged at the factory on a single skid. Assemblies to be
mounted in the transmitter are packed in crates. The skid and crates may contain
one or more precaution labels or markings. These markings provide information
regarding the various precautions that should be observed during the handling,
unpacking, and storage of the equipment crate. Examples of these precautions may
include positioning, fragility, and weather constraint labels.
NOTE: Acceptable storage climate for the equipment crate is between -30ºC to +60ºC.
5.5.1
Unpacking and Inspection
Before taking delivery, and prior to removing the contents of the crates, examine the exterior of
the crates for evidence of shipping damage. If any damage is visible to the crate or the contents,
do not continue to unpack the equipment. Protect the goods from further damage and contact
the freight carrier and Thales immediately for further instructions.
If the crate is free from damage, the equipment may be carefully removed. The following tools
are recommended for the unpacking process:
x Cutter
x Screwdriver
Remove the packing slip from the cover of the crate. Using the screwdriver, remove the top
cover and one of the sides of the shipping crate. With the cutter, carefully cut through the cover
material. Be careful not to damage any equipment during this process.
Once the equipment has been removed from the crate and verified against the packing slip,
inspect the equipment for any signs of damage. If any damage is visible, contact Thales
immediately for further instructions. While unpacking, carefully compare packing list with the
equipment, checking for in-transit damage at the same time. Should any damage be noted,
notify the freight carrier at once to file a freight claim. Do not discard any packing material until
told to do so by the carrier. Also, notify Thales Broadcast & Multimedia of any damages or
missing materials from the shipment. Retain original boxes and internal packing materials to
adequately protect equipment to be returned to the factory for repairs, upgrades, or
modifications.
5.6
Environment Considerations
The equipment housed in outdoor enclosures can be safely operated in ambient temperatures
of -15º to +45º Celsius (5º to +113º Fahrenheit) The RF power regulation and frequency
determining devices are qualified to operate across -30 to +50º Celsius (-22º to +122º
Fahrenheit) However, the channel filter will tolerate much less temperature variation. Therefore,
if not installed in a qualified outdoor enclosure with HVAC system, Thales recommends that the
transmitter be operated within r10q Celsius from room ambient. Moderate temperatures
generally extend equipment life. Although the equipment may be operated with relative humidity
Specifications

Affinity® LBD-200C-N1 Transmitter
Product Manual
of up to 95%, the equipment must be protected from conditions that cause condensation within
the equipment. The transmitter chassis requires a rack with a minimum of 24” vertical front-torear rail separation. If a rear door must be used to secure the rack cabinet, the rack must be at
least 40” deep to accommodate transmitter cabling, and the door must open fully or be removed
to allow transmitter maintenance. If a rear door is placed on the rack, forced ventilation through
the cabinet is required (600 cfm minimum per transmitter is recommended) and an air or
temperature interlock should be incorporated for protection against interruption of ventilation
(contact Thales Broadcast & Multimedia Customer Service department for assistance). In case
of indoor installations, the area should be kept dry and clean. There should be sufficient space
in front of the transmitter cabinet for service personnel and test equipment. A minimum of 44”
behind the cabinet should be free for rear cabinet access and air movement. Also, ample room
must be available at the cabinet rear for cable placement.
5.7
System Grounding
For proper system operation, it is imperative that the system be adequately grounded. Each
individual equipment-rack requires grounding to the main building ground. The basic grounding
scheme is provided below:
A: User Ground: Tie to building ground
B: Internal Ground Bar: Phone line Interface

Affinity® LBD-200C-N1 Transmitter
Product Manual
6 General System Description
The Thales Affinity® LBD-200C-N1 low power solid-state DVB-H transmitter is intended to
provide maximum flexibility for site layout and installation. The Affinity® transmitter contains
integrated modular assemblies that were designed to fit into EIA standard 19” rack units. The
transmitter consists of several of these rack units that house, with the exception of the
Downconverter Module, RF filter and HVAC unit, the major components that make up the
transmitter system. This module design allows operators of the transmitter to easily install,
operate and maintain the equipment.
The basic topology of the Affinity® LBD-200C-N1 transmitter configuration is as follows:
x Site Management System
x Satellite Receiver and
Remultiplexer
x Sirius DVB-H Exciter
x Front-End Power Supply
x Driver Section
Power Supply Module
Upconverter Module
Downconverter Module
x Power Amplifier (PA)
Segments
x UPS system
x RF Filter
x Phone System Interface
x HVAC Unit
The low power microwave
transmission system transmits a
digitally modulated average power
signal on a single 1670-1675MHz
channel. The LBD-200C-N1
generates 200 watts average power using a COFDM modulation scheme.
Digital transmission techniques provide superior performance over analog methods with
reduced susceptibility to noise and co-channel interference. COFDM modulation provides
exceptional throughput and spectral efficiency, while meeting the needs of mobility. The system
architecture is based on: advanced transistor technology, low-loss power combining, and
distributed control and power conversion. Some unique advantages of this new design are:
flexibility/scalability, lower downtime, and lower operating costs. The modular structure of this
System Description
- 31 -
Affinity® LBD-200C-N1 Transmitter
Product Manual
system allows for quick and easy replacement of malfunctioning plug-in modules resulting in
less downtime and convenient scalability. The high efficiency design and small size decreases
operating expenses. Each of the plug-in modules is self-managing. When a fault occurs within a
module, the application software detects and automatically signals and/or records the fault. If a
catastrophic failure occurs within any of the plug-in modules, the Master Support Interface (MSI)
system will detect the failure and perform an automatic controlled shutdown.
One key benefit of this series of transmitters is the “Hot Swap” replacement capability. The hot
swap feature allows the transmitter to continue functioning while a faulty power amplifier
segment is replaced. During replacement the transmitter will continue operating with only slight
power loss and with little to no change in the noise floor. Full transmitter power will be restored
when the replacement amplifier is plugged into the amplifier chassis.
Should any of the other plug-in modules contained in the transmitter require replacement, a brief
transmission interruption will occur when the faulty plug-in is removed. Transmission is restored
when the replacement module is plugged in.

WARNING
This equipment utilizes a grounding plug on all power cords. For personal safety, do not
defeat this feature. As with all similar types of equipment, high voltage can be accessed when
the chassis cover is removed. Special care should be given in areas of fuses, line switches,
and power supplies. Modern high power solid-state equipment contains low output voltage
power supplies with very high current capability. To prevent severe burns, avoid contacting
these circuits with conductive jewelry such as rings, watches etc. When servicing the
transmission line and antenna, care must be taken to avoid exposure to high-energy
microwave.
7.1
Installation of Transmitter Sub-Chassis
The transmitter modules require twelve rack units of vertical rack space (not including the
exciter).
Install the LBD-200C-N1 support rails within the equipment rack as shown in the site-specific
cabinet layout diagram. Failure to use the support rails will result in damage to the transmitter
chassis. Install rack clips to secure the transmitter front panel. Slide the chassis onto the
support rails and secure to the rack clips. The rear door of the transmitter opens for
maintenance access. Nothing should be mounted to the rear of the rack that will interfere with
this access.
Ensure AC power outlets and other brackets are appropriately located so as not to block the
rear of the transmitter. To ensure that no electrical arcing occurs, perform the installation of the
individual module segments of the transmitter in the order discussed below:

10.1.1 Remote Operation
(Optional)
For SD configuration the remote operation is enabled by either the SNMP agent or the Web
server, both of which are embedded in the Sirius DVB-H RF Exciter.
10.1.2 SNMP Agent and Web Server
The objective of the SNMP agent is to ensure remote operation of the equipment by using the
SNMP protocol by means of the IP protocol supported by an Ethernet interface.
The SNMP agent is responsible for:
x Communication with the equipment by means of SNMP protocol
x Communication with the equipment by sending e-mail
x Implementation of FTP and TELNET protocols
The control of the equipment in this manner is only enabled when remote operation is selected.
The SNMP agent in both local and remote modes of operation always accepts monitoring
requests.
Access to the SNMP agent for either writing and/or reading is organized by means of user
profiles defining individual rights and conditions for access. The SNMP agent integrates SMTP
protocol allowing events to be sent via e-mail. Important events will automatically generate
“traps”. The links between events and traps are configurable by the operator.
A web server allows the equipment to be controlled from any standard browser by means of the
HTTP protocol. The control of the equipment in this manner is only enabled when remote
operation is selected. The web server, in both local and remote modes, always accepts
monitoring requests.
The web server provides:
x Static information such as leaflet and user manual of the equipment
x Dynamic information including displays of all status alarms and faults, and operating
parameters
x Operating or configuration control protected by means of user profiles and
passwords
x Access to equipment logbook
The following screen shots represent the main page and the page dedicated to the Sirius DVBH RF Exciter. These should provide an accurate representation of the capability of the
embedded web server.
