15 Front-End Power Supply Description
The Front-End Power Supply Module provides the 48VDC level required to power the Driver
and PA Modules of the Affinity LBD-200C-N1 transmitter .The Front-End Power Supply Module
outputs the 48VDC to the connector boards located within the Sub-Chassis Assembly. The
Driver and Amplifiers derive the power from these connector board assemblies.
The Front-End Power Supply Module is a 4000-Watt device containing current limiting, thermal
shut down, and fuse protection circuitry. The required input voltage is 208VAC 3-phase @
50Hz.-60Hz. The nominal output voltage is +48VDC. A potentiometer on the Front-End Power
Supply Module is used to adjust the output supply level (factory adjust).
LED indicators located on the supply front panel assembly provide visual feedback of Front-End
Power Supply operation.
Two internal 600 CFM forced air fans provide convection cooling for the Front-End Power
Supply Module.
The Front-End Power Supply is plugged into the Power Supply Adapter located in the Chassis
assembly.
The 5.25” high, Front-End Power Supply Chassis can contain up to three 48VDC power
supplies. The rack is designed to allow the power supply modules to operate in a current
sharing mode when more than one module is installed (N+1 applications). The Power Supply
Chassis operates off the mains AC power and is fuse protected on TB1.
A circuit breaker assembly is attached to the rear of the chassis to provide DC over-current
protection for the PA Modules.
The Front-End Power Supply Modules are “Hot Swap” compatible. When operated in N+1
configurations, defective supplies may be removed and replaced without shutting the entire
transmitter system down.

16 Backplane/Interface Board Description
16.1 Front-End Power Supply Backplane
The Front-End Power Supply Backplane is the electrical and physical receptacle for the
Front-End Power Supply assemblies. The backplane board is mounted to the Affinity® Chassis
and provides AC voltage to the Front-End Power Supplies. The DC output voltages from the
Front-End Power Supplies are applied to the backplane to be used as a source of power for the
Driver section and PA plug-in modules. The Front-End Power Supply Backplane also contains a
diagnostic interface that can be used, via the Omnitronix SL81 Status Monitoring and Control
System (SMCS), to monitor Front-End Power Supply status.
Front-End Power Supply Backplane board
AC power from the rear panel enters the Front-End
Power Supply Backplane board through connectors J3,
J4, and J5. The AC source enters the Front-End Power
Supplies through backplane connector J11. DC output
power from the Front-End Power Supplies is present on
J12 of the backplane board where it is distributed to the
other modules via backplane connector studs J6 and
J7. The 24-position dual row connectors, J1 and J2, are
used to communicate and monitor the other modules in
the sub-chassis. Three-position single row connector J9
and nine-position single row connector J10 connect to
the amplifier motherboard to establish communications
between the Driver Backplane board and PA segments.
16.2 Driver Backplane
The Driver Section (Power Supply and Upconverter modules) is electrically, and physically
connected to the Driver Backplane when plugged into the Chassis assembly. The connectivity
is established when the push-button switch located on the backplane is depressed. This occurs
when the Driver Section Power Supply is plugged into the Chassis. Removing the Driver
Section Power Supply Module will also remove power from the Driver Backplane. This is done
to prevent arching during a Hot Swap operation.
The Driver Backplane provides +8VDC, +12 VDC, -12 VDC, +24VDC and ground for the Driver
Section. The Driver Backplane also contains multidrop communication connectivity used by the
Driver Section assemblies.

Driver Backplane
The Driver Section Power Supply module supplies the Driver
Backplane and Upconverter module with 5VDC, 12 VDC, –12 VDC,
and data through 48-pin DIN connections (1). The main power to
the Driver Section Power Supply plug-in is delivered through a sixposition blind mating connector (2) that is supplied by a push
button switch (3) activated by plugging the Power Supply module
in. Pins attached to the rear panel of the modules provide module
grounding through the grounding sockets (4). A five-position single
row header (5) and a 24-position dual row header (7) allow external
data exchange. Two six-position single row headers (6) supply the
RF modules with power and communications. A redundant driver
assembly may be achieved by connecting two backplane boards
together via the two five-position single row headers (8).
16.3 PA Backplane
The PA Modules are electrically and physically connected to the PA Backplane when plugged
into the Chassis assembly. The PA Backplane contains float-mounted, blind-mating receptacles,
and blind-mating headers for module alignment. The PA Backplane provides +48VDC and
ground for the PA Module segments. The PA Backplane also contains RS485 multidrop
communication connectivity used by the PA Module assemblies. A two-position Dual Inline
Package (DIP) switch located on the PA Backplane is used to enable or disable control and
diagnostic access via the RJ11 connector located on the front panel of the PA Modules.

16.5 RS-485 Communication Board
An RS-485 Communication Board is mounted to the inside rear of the Driver Section. The
board monitors the RS-485 communication traffic on the system bus. A common
computer/master control station can monitor up to 32 RS-485 devices on the network.
The RS-485 Communication Board is equipped with two RJ11 6-pin telephone type receptacles.
The cables used to daisy chain (parallel) the RS-485 devices to the host are shielded double
twisted pair.
A mini double-pole double-throw (DPDT) dipswitch labeled NETWORK END TERMINATION is
accessible on the RS-485 Communication Board from the back panel of the Driver Section. In
an RS-485 network, all RS-485 devices in the daisy chain series, with the exception of the last
RS-485 device in the network, have the dipswitch set to OUT. The last RS-485 device in the
network has the switch set to TERM. Placing the switch in TERM terminates the communication
bus with the required impedance.

16.6 Master Support Interface Board
Overview
The Master Support Interface (MSI) Board assembly performs several functions within the
Affinity transmitter.
x Interface to external management
system.
x Control and monitoring of the plug-in
modules, via communication and
electrical interfaces
x Management (control, fault
notification) of modulator
x On-board Master Reference Oscillator
(optional, for DVB-H applications)
x Fast response PA module (Amplifier
plug-in) protection
Hardware systems
The MSI hardware performs various hardware functions and provides a platform for the
management of the internal transmitter components. The circuitry contains a primary
microcontroller (Main MCU), a primary programmable logic device, or CPLD (Main CPLD), and
an MCU and CPLD dedicated to an auxiliary serial port provided by the transmitter (Port MCU
and Port CPLD). Other key circuitry includes a Master Reference Oscillator system, Power
Amplifier Segments manager, Fast ALC Reduction circuit, and Remote and Local serial busses.
Backplane/Interface Boards

Affinity® LBD-200C-N1 Transmitter
Product Manual
Remote Serial Interface
External high-level management systems connect to the Affinity® transmitter using the
transmitter Remote RS-485 interface. The electrical interface consists of: an RJ-11 jack located
on the Affinity® rear panel, a wire harness located inside the Affinity® chassis, and the RS-485
transceiver circuit located on the MSI circuit board assembly. SNMP management is provided
through the Omnitronix SNMP Device Server.
Local Bus System Controller
The MSI acts as a master on the Local RS-485 network located inside the Affinity® chassis. As
the master on the network, the MSI sends query and command messages to the slave devices
on the Local network, and receives responses from the slave devices. The Upconverter plug-in
is a slave device.
The Local bus support circuitry consists of:
Auxiliary Serial Port
An RS-232 transceiver, and dedicated MCU and CPLD circuits are provided on the MSI to
support an auxiliary RS-232 serial port (aux port). The port system consists of the transceiver
and controller circuits on MSI connector J13, and harnessing to the rear panel DB-9 male
connector. The auxiliary serial port is typically used to interface a modulator to the Affinity®
transmitter.
Master Reference Oscillator
The Master Reference Oscillator (MRO) system on the MSI receives a 10 MHz reference input
on MSI SMA connector J17. The MRO phase-locked loop (PLL), which contains an on-board
VCO, locks to the reference input. The VCO output signal is fed to two SM connectors, J16 and
J19. These are used to feed the Affinity® Local Oscillator and the modulator (optional). A
tracking mechanism is provided that follows the control voltage applied to the VCO. Should the
10 MHz reference input be removed, the tracking holds the VCO at the last stable position of the
VCO. This helps maintain the transmitter on frequency, even after loss of reference input.
PAS Manager
The Power Amplifier Segments (PAS) are contained in the same chassis as the MSI. This group
of amplifiers is called a “quad”.
The PAS Manager of the MSI protects the amplifiers from damage that could occur following
failure or removal. When an amplifier fails, the output power of the transmitter is reduced. The
transmitter ALC will attempt to correct the reduction in power by increasing the drive level
applied to the remaining amplifiers. Since this can result in overdriving the remaining amplifiers
and potentially damaging the device(s), the PAS Manager reduces the ALC level to a factorycalibrated level. The transmitter power is reduced predictably (Fast ALC Reduction). The PAS
status signals are monitored on connector J7 of the MSI. Failed PAS location numbers are
stored in a CPLD register and read by the Main MCU for monitoring and fault notification.

Product Manual
Firmware Systems
The MSI contains four firmware programs: the Main MCU program, the Main CPLD program,
the Port MCU program, and the Port CPLD program. Interaction of the various firmware
programs is described below.
Main MCU Firmware
The Main MCU program (main firmware) is the most complex of the four programs. This
program is responsible for supporting the Local and Remote serial interfaces, MRO, and PAS
Manager, as well as passing commands to the Modulator, and receiving fault notifications from
the Modulator.
Remote Serial Bus Support
The main firmware receives TNET protocol Remote serial commands and requests. Commands
may be issued by using the Omnitronix SNMP Link SL81 management device. The commands
may be used to change the values of calibration variables stored in MSI non-volatile memory.
For a list of these variables, refer to the SNMP document.
Commands may also be issued to change the settings and behavior of the Modulator. Refer to
SNMP document for a list and description of the available Modulator commands. The main
firmware is stored in flash memory. The firmware may be updated using a terminal emulator to
issue updated commands to the transmitter, and to transfer the updated firmware file to the
transmitter.
Status of the Affinity® transmitter is collected by means of status queries sent to the MSI
Remote serial port. The MSI responds to these requests with a response message in a
predefined format, containing values of monitored variables. In transmitters having an internal
SNMP Device Server, the Device Server repeatedly polls the status of the Affinity® transmitter
with status queries sent to the MSI.
Local Serial Bus Support
The MSI Main MCU, through firmware, implements a master device on the Affinity® internal
Local serial bus. The master device issues requests and commands to the Upconverter on the
bus, which is a slave device (i.e. this node cannot issue a request or command, but can only
receive requests/commands and respond). Through frequent Local bus queries/responses, the
MSI collects the status of the Upconverter. In addition, the MSI can send commands to the plugin causing changes in operation such as: changing the operating channel, or setting the system
to STANDBY or ON AIR.
Master Reference Oscillator Support
The MSI main firmware monitors and controls the on-board Master Reference Oscillator (MRO).
The main firmware monitors the MRO PLL VCO control voltage using an A/D converter. The
MSI uses the measured voltage to determine a second control voltage to be applied to the PLL
that follows the MRO PLL VOC control voltage. A D/A converter on the MSI generates the
output. As the VCO control voltage changes slowly with time, the D/A voltage tracks the VCO
voltage. If the 10 MHz reference input to the transmitter is removed, the tracking voltage is
Backplane/Interface Boards
- 129 -
Affinity® LBD-200C-N1 Transmitter
Product Manual
frozen by the main firmware thus minimizing disturbance to the transmitter. When the input is
reapplied, the tracking resumes.
PAS Manager Support
In the Power Amplifier Segment (PAS) quad system, the MSI monitors two signals, PAS_fault
and PAS_presence, for each PAS. The monitoring is performed in the Main CPLD in a system
called the PAS Manager. The failed PAS is detected by the MSI main firmware by reading the
registers in the Main CPLD.
The MSI main firmware uses a calibration variable QUAD_MASK to inform the MSI CPLD of the
number of installed PAS modules. This is necessary to set the proper ALC reduction for the
given number of PAS.
Auxiliary Port Management
The MSI Auxiliary Serial Port (aux port) is used to monitor and control a device connected to the
Affinity® transmitter, such as a modulator. The Port MCU handles port management; however,
the commands and requests for status of the modulator originate in the top-level management
system and pass through the Main MCU as TNET serial messages. The Main MCU copies the
command or status request from the TNET message and passes the request to the Port CPLD,
which sends the appropriate control or monitoring message to the managed port device.
Refer to SNMP document for a list and description of the variables managed in the auxiliary
equipment connected to the Auxiliary Port.
Port MCU Firmware
The Port MCU is dedicated solely to the management of a device connected to the Auxiliary
Serial Port. Equipment such as a modulator may be connected to the aux port. In the factory,
the firmware program appropriate to the end-user’s purchased equipment is loaded in the Port
MCU.
The Port MCU periodically reads fault alarms for various modulator systems from the modulator
and writes the conditions of the systems (pass/fail) to the Port CPLD. The alarm status is
available to the Main MCU for fault notification to the top-level management system.
At any time, the top-level management system can issue a command to the modulator. The
command is received by the Main MCU and passed through the Port CPLD to the Port MCU.
The Port MCU develops the corresponding message with arguments given in the original
command, and sends messages to the modulator connected to the aux port.

System Configuration
During factory set-up and test, the various transmitter systems under the control of the MSI are
configured, and settings stored, in the MSI non-volatile memory. Some configuration settings
are used to enable and set-up optional resources of the MSI. The settings are stored in
“personality” variables. In general, users should not change variables, but the user can read
back the values of the variables to recall the available MSI resources. The variables are briefly
described below. For a more detailed description of the personality variables, refer to the SNMP
document.
x On Board Resources Personality (OBR_PERSON) – enables or disables MSI
systems such as PAS Manager for quads and MRO.
x Local Serial Bus Personality (LOCAL_PERSON) – enables or disables local serial
communications with the plug-in modules.
x Auxiliary Serial Port Personality (PORT_PERSON) – enables or disables the Aux
Port system.
16.7 True RMS Detector Module
The signals coming from the directional coupler feed the
True RMS Detector Module with both the forward power
and reflected power proportional to the transmitter output.
The input attenuator matches the directional coupler port
and level to the detector.
The RMS Detector Module is based on a true RMS
detector-chip that provides linear RF detection with high
sensitivity. The log function of the detector allows for the
measurement of the rms power independent of the peakto-average ratio of the specific waveform of the
transmitting signal. Temperature compensation and fault
detection are provided with the circuit.

and cabinet air conditioning systems. In the ambient system, air enters through the front of each
chassis and exits the rear. Amplifiers use folded-fin heatsink technology for increased cooling
efficiency. The Upconverter chassis uses a similar cooling arrangement with low volume fans for
the lower associated heat dissipation. Accompanying the forced air-cooling systems is the
enclosure air conditioning system sized according to the heat load expected by the transmitter
and ancillary equipment.

Affinity® LBD-200C-N1 Transmitter
Product Manual
20 Affinity Transmitter Control Systems
The upconverter amplifier (UCA) control system (driven by multiple microprocessors) monitors
and controls all of the transmitter sub-assemblies, and provides transmitter status information to
the operator.
A user-friendly man/machine interface is provided by:
x A front-panel control interface for menu driven commands (select, enter, escape, &
exit buttons).
x A front panel LCD screen located on the driver module providing transmitter status
information (status of transmitter, output power, power supply, local oscillator, and
upconverter).
The transmitter safety system is hard wired, which allows for real-time processing, and is
independent of the control system.
20.1 Automatic Control Systems and Monitoring
Automatic control systems protect the transmitter against VSWR problems and excessive air
input temperatures by affecting successive restarts---first at the nominal power---then at –3dB
while maintaining the transmission quality at the level obtained at nominal power output.
Approximately, a 30-second delay will occur between the restarts. The transmitter is
automatically shut down if the fault persists.
The transmitter is also protected by a safety system that causes amplifier module shutdown
(due to excessive transmitter temperature, etc.). Monitoring of operational parameters, alarms,
power output, VSWR, status of amplifiers, drivers and safety loops are available.
20.2 Status Monitoring and Control System (SMCS)
The Omnitronix SL81 Status Monitoring and Control System (SMCS) is provided for use with
the Affinity® LBD-200C-N1 transmitters. The SMCS is a rack-mounted unit located within the
transmitter cabinet. It provides a web interface and an SNMP agent for remote control. Remote
access to the SNMP agent is available through a GSM connection or via dial-up modem and a
PSTN line. All events and faults are stored in a logbook with date and timestamps.
20.2.1 SMCS Functions:
Controls
The SMCS has the ability to access the On (transmit), Off (standby), and Reset commands.
Other operational commands, monitoring and safety controls, and diagnostic help system are
available. The SNMP manager program can be used to browse the MIB of a connected device
and select variable(s) to be modified.
Affinity® Control Systems
- 141 -
Affinity® LBD-200C-N1 Transmitter
Product Manual
Fault Log System
The fault log system within the SMCS records transmitter status changes (using time and date
coding) and enables detection and identification of faulty sub-assemblies. This event data is
stored in the history log in non-volatile memory.
The parameters in the history log can be sorted and viewed several ways including: view by
general chronological event and view by parameter. This information can be printed and
exported from the SMCS for use with a typical database management system for further
analysis.
Remote Control
The SNMP remote control system of the SMCS requires the use of a third-party element
management system. It can be configured with either a dial-up modem interface or a GSM
connection. All functionality of the local SMCS system is available to a user using the remote
version (including control commands). Access to the SNMP agent for either writing and/or
reading is organized by means of different user profiles defining the individual access rights.
The SNMP TRAP operation is used to asynchronously send event information to the remote
manager. The agent generates a TRAP message when one or more of the predefined
conditions occur. The link between events and traps are configurable. The SNMP agent also
integrates the SMTP protocol, allowing it to send email on events.
External Contact Closure Monitoring
In addition to internal transmitter system monitoring, the SMCS system allows the monitoring of
several external contacts and alarm signals. The SMCS system is provided with a peripheral
input/output system (PIOS) that provides the station the capability to monitor up to twelve
contact closures. The system has three dedicated ports for fire, security, and environment. The
user can name the remaining external contact closures through the GUI. This provides the
flexibility to monitor anything at the transmitter station that can be interfaced to the contact
closures provided in the PIOS (tower lights, generator status, UPS alarm, etc.).

Affinity® LBD-200C-N1 Transmitter
Product Manual
21 The Affinity® Quick Start Procedure
Each Thales transmitter is factory calibrated, and requires only a minimum start-up procedure to
ensure proper operation. The appropriate steps for the installation of the Affinity® transmitter
system and its ancillary equipment must have been performed prior to initiating this procedure.
Please consult the installation and cabling sections of this manual before powering up any
equipment. Verifying that all cables and electrical connections are in place is crucial. Read this
section entirely, along with the calibration section, prior to beginning the transmitter power
initiation process.
1. Start by ensuring that all of the amplifier modules are turned off via the front panel key
switches.
2. Apply AC power to the UPS system; follow the manufacture’s turn on guidelines.
3. Apply AC power to the site management system; follow the manufacture’s turn on
guidelines.
4. Apply AC power to the satellite receiver; follow the manufacture’s turn on guidelines.
Ensure a proper ASI feed is available to the Sirius DVB-H Exciter.
5. Switch on AC power to the Affinity® Upconverter amplifier chassis(s). Observe that the
AC fan has begun to operate (fan noise will be heard).
6. Turn on the 48V Front-End Power Supplies; all plug-in modules should indicate proper
DC output via their LED display. Also, observe that the driver sections including the
multi-output Power Supply Plug-In and Upconverter have begun their initialization (a
small time lag is normal -- under 5 seconds typical).
7. Switch on the Sirius DVB-H Exciter. Using the exciter front panel MMI, turn off adaptive
pre-correction if enabled and place in flat response mode (first go to frozen mode then
go to flat mode).
8. If available, use a spectrum analyzer to verify the exciter output level -18dBm r 1dB.
Adjust if required. Observe the exciter output, perform cancellation of LO or image
rejection via local MMI or SIRUIS setup GUI interface (this is a factory calibration and
should not be required).
9. Connect exciter output to the Upconverter amplifier chassis (UCA) UHF input.
10. Ensure 1GHz Local Oscillator connection via exciter and UCA.
11. Connect power meter to output coupler.
12. Ensure that the transmitter output is connected to an appropriate sized 50-ohm station
load. Note: the return loss of the load should be greater than 15 dB at minimum.
13. Switch on all power amplifier (PA) front panel key switches while observing the power
meter.
14. Using a power meter, ensure proper power output. Also, if available, observe channel
spectrum output shoulder performance; shoulder should not exceed -29dBc from flat top,
RES BW 30kHz VBW 3kHz. Span 15MHz. marker at 1672.5MHz delta r2.64MHz.
Quick Start Procedure

Affinity® LBD-200C-N1 Transmitter
Product Manual
15. If required, raise or lower power (see calibration sections below for process). Note that
some sites may require power to be re-adjusted to compensate for antenna feed line
loss. This is normal, and is site specific. The Affinity® system, as calibrated by the
factory, will not allow the transmitter rated power output to be exceeded by more than
1dB. This 1dB margin is intended to compensate for transmitter drift with ageing, and
serves as the power limiter for transmitter safety and protection against overdrive
damage. Thales requires that the transmitter be operated at or below rated output, and
that the total effective radiated power at the antenna terminal(s) not exceed the FCC
limit of 2kW for this wireless service under part 27 of the commission regulations.
16. Recalibrate meter if required, see calibration process below.
17. Enable adaptive non-linear pre-corrector via front panel MMI. First, place the precorrector in frozen mode, then enter adaptive mode. Observe shoulder performance via
spectrum analyzer and /or exciter front panel display; shoulder level greater than 34dBc
is acceptable, 36 dB is typical.
18. Enable adaptive linear pre-corrector via front panel MMI. First, place the pre-corrector in
frozen mode, then enter adaptive mode. Observe frequency response and group delay
through appropriate measurement technique.
19. As a safety precaution, place the transmitter into standby; also remove the UHF input to
the UCA. Now, connect the transmitter output to the antenna system. Note that the
return loss of the antenna should be greater than 15 dB at minimum.
20. Reconnect the UHF input and place transmitter into transmit mode.
21. See that shoulder performance and linear response has not changed with connection to
antenna system.
22. Ensure digital transmission quality by the appropriate demodulation and signal analysis
techniques.
NOTE: If this is the initial turn on, Thales recommends that the full site proof be conducted in
accordance with the provided field proof and handover documentation. All required data should
be recorded within that specific documentation. Typically, a Thales field engineer will conduct
this site turn-on process test during the site installation and proof. This eliminates the need for
any specialized test equipment by the product end-user. Once the system is setup, the
customer may maintain and view operating parameters via the onboard control and diagnostic
tools, which have been designed for ease-of-use, and to minimize the operator’s cost of
maintenance.
Setup & Detailed Alignment Procedures - 145 Affinity® LBD-200C-N1 Transmitter
Product Manual
22 Setup and Detailed Alignment Procedures
The normal start-up procedure for installation and operation of the Thales transmitter is found in
the Affinity® Quick Start Procedure outlined in the previous section. In most cases, detailed
maintenance calibration may be achieved by running the “Affinity Control GUI” software tool,
which is typically loaded on a laptop computer.
NOTE: The user should be familiar with this software prior to attempting any calibrations. Refer
to the Affinity Control User’s Guide document number # 47267151-108 for a detailed description
of software operation.
Manual Alignment Process
22.1 Power Limiter & Manual Gain Calibration
1. Using the front panel key switches, place the PA modules to the OFF/UNLOCKED
position.
2. Using EMSET, Set ALC MODE SELECT = 0.
3. Connect a cable to the RF Sample Output located on the preamplifier front panel.
4. Set POWER LIMITER value to zero. At this point, maximum output power should be
+9dBm from the preamplifier direct output. Measured at front panel, sample would be 21dBm max.).
5. Set ALC MODE SELECT = 1.
6. Set ALC AUTO REF to 4095.
7. Using the front panel key switches, place the PA modules to the ON/LOCKED position.
8. Raise the POWER LIMITER value until power is 1db above the nominal power.
9. Set ALC MODE SELECT back to 0.
10. Raise ALC MANUAL REF from parameter value of zero until nominal power is achieved.
11. Set HEALTH SNAPSHOT 65535 to clear any faults.
22.2 Forward Power Calibration
1. Using EMSET, Refresh the monitored variables under normal debug mode 1.
2. Under monitored variables frame, read values displayed in the second row. The value in
the cell titled LOW is multiplied by 256 and added to the value in the cell titled HIGH.
The resulting value from this operation is now entered into the SYSTEM FORWARD
POWER REFERENCE parameter.
3. Use EMSET to set ALC AUTO REF until the transmitter output power is 6dB +/- 0.1dB
lower than nominal output power. This -6dB setting is critical for the accuracy of the front
panel display.
Setup & Detailed Alignment Procedures - 146 Affinity® LBD-200C-N1 Transmitter
Product Manual
4. Using NORM DEBUG MODE 1, read the values displayed in the second row. Multiply
the value in the cell titled LOW by 256 and add this to the value in the cell titled HIGH.
Record the total value.
5. Locate the correct setting partition, you should see two fields: one labeled address, and
the other labeled Data. Enter 65 into the address field.
6. Enter the recorded value from the step above into data and click send. At this point, the
scale factor will be incorporated into the meter system.
7. Confirm that 25% is displayed on the front panel meter under SYSTEM FORWARD
POWER.
8. Now close EMSET 4.1, and reopen EMSET 5. Connect as before.
9. Raise ALC AUTO REF until system reaches nominal power and 100% on the front panel
meter.
10. This completes the forward power meter calibration.
11. Set HEALTH SNAPSHOT 65535 to clear any faults.
22.3 Automatic Level Control
1. Using EMSET, Place system back to auto ALC mode by setting ALC MODE SELECT =
1.
2. Lower ALC AUTO REF until system reaches nominal power.
3. Perform linear and non-linear pre-correction of transmitter using the front panel menu via
the Exciter (see below). After correction, the exciter output level should still be at 18dBm. If not, readjust output back to this nominal level.
4. With the exciter now at -18dBm, If necessary, go back to refine ALC AUTO
REFERENCE to nominal power after correction.
5. Set HEALTH SNAPSHOT 65535 to clear any faults.
22.4 Upconverter Power Meter Calibration
1. Refresh the monitored variables under normal debug mode 1.
2. Under the monitored variables frame, read values displayed in the eighth row. The value
in the cell titled LOW is first multiplied by 256 then added to the value in the cell titled
HIGH. The resulting value from this operation is now entered into UPCONVERTER
FORWARD POWER REFERENCE parameter. This completes the preamplifier meter
calibration.
3. Set HEALTH SNAPSHOT 65535 to clear any faults
22.5 Reverse Power Calibration
1. Verify the level at the TRU-RMS Detector is +5dBm +/- 2dbm. If not, troubleshoot. (The
level is determined by a fixed coupling factor and fixed attenuation values based on
transmitter output power rating; if the level is out of tolerance, something is wrong in the
RF chain.)
Setup & Detailed Alignment Procedures - 147 Affinity® LBD-200C-N1 Transmitter
Product Manual
2. In order to calibrate the reflected meter, swap the forward sample and reflected sample
cables on detector module.
3. Set NORMAL DEBUG MODE = 1(For a complete explanation of debug modes see
DOC#25-0021). The screen will auto refresh. Note, that the variable names no longer
represent actual parameter. DOC# 25-0021 explains the function of each parameter
under the various debug modes. (Normal debug mode = 1 is used for meter calibration.)
4. Under the monitored variables frame, read values displayed in the third row. The value
in the cell titled LOW is first multiplied by 256 then added to the value in the cell titled
HIGH. The resulting value from this operation is now entered into SYSTEM
REFLECTED POWER REFERENCE parameter. This completes the reflect meter
calibration.
5. Return the cables to normal position.
6. Set HEALTH SNAPSHOT 65535 to clear any faults.
22.6 Calibrate Fast Reflected Shut Down
1. Sample the Transmitter output using an inline variable attenuator. Set the level to -5dBm
and connect this signal to the reflected port of TRU RMS detector module.
2. Raise level slowly until the preamplifier LCD display of reflected power reads 15%.
3. Lower the FAST REFLECTED THRESHOLD until the power is reduced by approx. 6dB
(this power reduction is pre determined) A typical value of fast reflected threshold =
1000. This threshold must be precise. Use smaller calibrations steps when reaching
near the value of 1000.
4. Once tripped, it will stay at reduced power. To verify or to recalibrate, lower the sample
and reset the module; use the reset button on the EMSET window for this purpose.
5. Verify that you can raise the reflected power percentage to at least 10% without the
transmitter tripping into the 6dB protection mode. Also, exceed the 15% mark to activate
the protection system. Again, reset the module back into normal operation when this test
is completed.
6. Set system reflected power percent limit to = 25.
7. Return all cables to normal position.
8. Set HEALTH SNAPSHOT 65535 to clear any faults.
22.7 Non-linear Precorrection
1. Navigate to the menu for non-linear calibration on the exciter front panel; this is located
under the F5 button on the keypad located below the display window [Press F5 once].
The feedback sample should be connected prior to the channel filter (default location).
2. Observe that the feedback level is Normal; see feedback level indicator (typical level is –
15dBm).
3. Apply a one-shot or place the correction in adaptive mode; allow a few seconds for
automatic correction.
4. Observe the shoulder level; ensure it is within tolerable limits (i.e. t34dB).

Product Manual
23.4 Schedules Maintenance
Use this maintenance schedule as a guide for the Affinity® transmitter. Maintenance procedures
may be performed more often if environmental conditions are not typical. Variables such as dirt,
heat and power-line variations, which may degrade the transmitter operation, should be
monitored and accounted for during any maintenance schedule. Keep the transmitter and the
surrounding area clean. The transmitter can fail if operated in an overheated and/or dirty
environment. Parts with accumulated dirt will not be as efficient and may prematurely fail. Dirty
fan assemblies reduce the amount of cooling airflow to the transmitter causing components to
overheat. It is important to note that all scheduled maintenance activity should be flexible
enough to accommodate any operational variance.
23.4.1 Monthly Maintenance
Perform the following checks on a monthly basis:
Operating Temperatures
During transmitter operation, and using a temperature probe, test the transmission line
components, waveguide, and other exposed components for abnormal temperature fluctuations.
Unusual hot spots on these components typically indicate a problem.
Visual Inspection
Visually examine the entire transmitter system. Look for loose connections, damaged
components, (discolored, charred, melted, broken leads) and dirty areas. Tighten all loose
connections; replace all damaged components, and clean dirty areas. Investigate and record
the cause for any of these issues.
Cooling System
Verify that all system cooling air displacement fans and air-conditioning units are in working
order. Ensure all fans are clean and unobstructed.
Cleaning
It is important to keep the Affinity® transmitter and related support equipment clean. For
example, a dirty air filter reduces cooling airflow and can cause a thermal runaway problem
inside the transmitter cabinets. Dirt makes a low-resistance path across insulators and wiring.
WARNING
Perform these procedures and checks only when
the voltage is removed from the transmitter.
Use a vacuum cleaner, small brushes, or clean lint-free cloths with denatured alcohol or milddetergent cleaning solutions. Do not use compressed air. Compressed air blows dirt around
Maintenance and Servicing

Affinity® LBD-200C-N1 Transmitter
Product Manual
rather than removing it. Use a small brush to dislodge dirt while using the vacuum to remove it.
Where practical, use cloth to wipe dirty surfaces. Clean the fans that pull air through the
transmitter. The amount of air that the fan can move is reduced if the impellers are dirty. Clean
the motors; dirt may accumulate on the windings and bearings that can increase the operating
temperature and decrease the life of the motor.
23.4.2 Semi Annual Maintenance
Perform these checks on a semi-annual schedule:
Plug-In Module Cleaning Procedure
This cleaning procedure is applicable to all the Affinity® plug-in modules.
NOTE: When plug-in modules are removed during the cleaning process there will be an
interruption in service. Returning the module to the sub-chassis will restore service.
This note does not apply to the Power Amplifier Segments (PAS). The amplifier segments may
be removed one-at-a-time for cleaning with the power attached. Removing an amplifier during
this cleaning procedure will cause a reduction in transmitter power until the amplifier is again
secured
x Remove the plug-in module by loosening the thumbscrew and sliding the module
out of the sub-chassis.
x Remove the side “snap-on” covers if required.
x Gently vacuum or dust inside the plug-in.
x Clean the outside covers and front panel using a damp (NOT WET) non-abrasive
cloth, and a mixture of mild detergent and water.
x Ensure that the plug-in module is COMPLETELY dry before plugging it back into the
sub-assembly.
x Tighten the thumbscrews
Power and Grounding Audit
The first step to avoiding power quality problems is to check the AC distribution and grounding
system for missing, improper, or poor connections. It is important to check the complete
grounding system from the source to the load. Checking the grounding system ensures that the
voltage drops are within acceptable limits and the ground connections are proper.
Wiring and Grounding Problems
When a neutral-to-ground connection is made at the load side of the equipment, the feeder
neutral current will divide and return on both feeder metal raceway and feeder neutral
conductor. When an AC current travels on the metal enclosure of the equipment, an
electromagnetic field is produced, which is not desirable. Grounding and wiring problems can
arise from inconsistencies in equipment installations, such as:
x Different parts of the industrial set-up were built during various time schedules.
Maintenance and Servicing
- 153 -
Affinity® LBD-200C-N1 Transmitter
Product Manual
x Electronic equipment with control ground and power ground makes the issue of the
system grounding more complex.
x In new installations, connections may be left off or may not be properly tightened.
x Loads cycling on-and-off produce heating and cooling that eventually result in poor
joints with high impedance
x Periodic additions or modifications to the distribution system can result in missing,
improper, and poor quality connections.
x Multiple control or power grounds belonging to different facilities and connected to
the same ground will cause loop currents.
x With the introduction of many converter and solid-state power supplies, the steady
state neutral current becomes significant, which is not desirable and has to be
monitored and corrected.
Acceptance Criteria
A grounding audit must be performed to ensure that acceptance criteria are maintained. Voltage
limits, and neutral and ground bonding must be evaluated. Voltage limits: Line-to-ground
voltage, and line-to-neutral voltages, must be within 5% of the nominal voltage as per ANSI
Standard 84.1. Any voltage deviation above or below the defined limit may affect equipment
performance. Voltage drop-in feeders that serve sensitive electronic equipment shall be no
more than 2% under the actual load conditions as per IEEE Standard 1100. This is not a
requirement, but this practice may help to achieve better equipment performance.
Neutral and ground bonding: A voltage measurement between the neutral and ground will
indicate voltage in the milli-volt range under normal operating conditions. A reading of zero volts
indicates the presence of a nearby neutral-ground bond. This condition is acceptable.
x Excessive current on equipment ground can indicate the presence of a load-side
ground connection. This condition requires careful visual inspection.
x Open or ungrounded equipment has to be identified by visual inspection. This
condition must be remedied.
Corrective Measures
The following are some of the typical items that require corrective measures followed by the
results of field measurements.
x Missing equipment ground connection. This ground connection must be installed.
x Missing interconnection from the industrial ground to the utility ground has to be
connected.
x Reversed connection between the neutral and the ground must be corrected.
x Multiple control grounds from the adjacent facilities connected to the same ground
to provide isolated grounding for the facility.
x Rectify loose ground connections. Loose connection in the ground connections
produces high impedance connection and has contact resistance.
Maintenance and Servicing
- 154 -
Affinity® LBD-200C-N1 Transmitter
Product Manual
x It is recommended that all grounding bonds be inspected and tested annually to
ensure proper and low impedance connections.
23.4.3 Annual Maintenance
Annual maintenance should consist of verifying that the transmitter is operating in accordance
with licensing authority Rules and Regulations. Use the factory tested transmitter data that was
initially provided with the transmitter, or any performance data taken after the transmitter was
installed. Use this information as a guide for completing the necessary tests, and as a
comparison to data recorded during the tests. Thales offers services to conduct these tests. For
more information, contact Thales Customer Service Department.
23.5 Troubleshooting
The Affinity® transmitter is equipped with comprehensive diagnostic circuitry that monitors the
status of each plug-in module and amplifier segment. The Affinity® front panel contains an LED
display that is used in conjunction with the installed Control and Monitoring system to diagnose
failure modes.
A 14-pin diagnostic interface connector, labeled J1 located on the back of the transmitter, is
used to assist in troubleshooting. Critical power supply, plug-in module, and motherboard
voltage test-points can be accessed from this location. Should a failure occur, the combination
of diagnostic status LEDs, the Control and Monitoring system, and the diagnostic interface
voltage levels will help identify the failure.
NOTE: Repair of internal modules is not recommended or advised. Contact Thales Customer
Service department should a failure occur to any of the plug-in modules or amplifier segments.
