1.1 SAFETY SUGGESTIONS
Regardless of how well electrical equipment is designed, personnel can be exposed to dangerous
electrical shock when protective covers are removed for maintenance or other activities. Therefore, it is
incumbent on the user to see that all safety regulations are consistently observed and that each individual
assigned to the equipment has a clear understanding of the first aid related to electrical shocks. (see next
pages)
In addition these safety practices must be followed:
Do not attempt to adjust unprotected circuit controls or to dress leads with power on.
Always avoid placing parts of the body in series between ground and circuit points.
To avoid burns, do not touch heavily loaded or overheated components without precautions.
Remember that some semiconductor cases and solid-state circuits carry high voltages.
Do not assume that all danger of electrical shock is removed when the power is off. Charged
capacitors can retain dangerous voltages for a long time after power is turned off. These capacitors
should be discharged trough a suitable resistor before any circuit points are touched.
Don't take chances. Be fully trained. Screen Service Italia equipment should be operated and
maintained by fully qualified personnel.
Do not service alone and do not perform internal adjustments of this unit unless another person
capable of rendering first aid and resuscitation is present.
Some components used in the construction of this equipment contain Beryllium Oxide (BeO). This
substance is harmless as it is, but becomes highly dangerous if it is ground to powder. Special
procedures of disposal must be observed in case of failure of these devices.
NOTE: This section is not intended to contain a complete statement of all safety precautions which
should be observed by personnel in using this electronic equipment or others.
Screen Service shall not be responsible for injury or damage resulted from improper procedures or from
using it by improperly trained or inexperienced personnel.

1.2 GENERAL SAFETY RECOMMENDATIONS
When connecting the equipment to the power, please follow these important recommendations:
This product is intended to operate from a power source that will not apply more than 10% of the
voltage specified on the rear panel between the supply conductors or between either supply
conductor and ground. A protective-ground connection by way of the grounding conductor in the
power cord is essential for safe operation.
This equipment is grounded through the grounding conductor of the power cord. To avoid electrical
shock, plug the power cord into a properly wired socket before connecting to the product input or
output terminals.
Upon loss of the protective-ground connection, all accessible conductive parts (including parts that
may appear to be insulating) can render an electric shock.
To avoid fire hazard, use only the fuse of correct type, voltage rating, and current rating. Refer fuse
replacement to qualified service personnel.
To avoid explosion, do not operate this equipment in an explosive atmosphere.
To avoid personal injury, do not remove the product covers or panels. Do not operate the product
without the covers and panels properly installed.
1.3 GOOD PRACTICES
In maintaining the equipment covered in this manual, please keep in mind the following, standard good
practices:
At regular intervals, the condition of the equipment and the correct functioning of protective and
safety devices shall be checked by a skilled person approved by the appropriate authority for this
duty. Functional checks shall be carried out on interlocking systems of doors, mechanical interlocks,
isolating switches, earthing switches, parallel resistances and protective devices against over-
voltages and over-currents. The above checks shall not be carried out after the protective and safety
devices have operated under fault conditions. The safety devices shall not be altered or
disconnected except for replacement, nor shall the safety circuit be modified without specific
approval of the appropriate authority in each case.
When connecting any instrument (wattmeter, spectrum analyzer, etc.) to a high frequency output,
use the appropriate attenuator or dummy load to protect the final amplifiers and the instrument input.
When inserting or removing printed circuit boards (PCBs), cable connectors, or fuses, always turn off
power to the affected portion of the equipment. After power is removed, allow sufficient time for the
power supplies to bleed down before reinserting PCBs.
When troubleshooting, remember that FETs and other metal-oxide semiconductor (MOS) devices
may appear defective because of leakage between traces or component leads on the printed circuit
board. Clean the printed circuit board and recheck the MOS device before assuming it is defective.
When replacing MOS devices, follow standard practices to avoid damage caused by static charges
and soldering.
When removing components from PCBs (particularly ICs), use care to avoid damaging PCB traces.

1.4 PROCEDURE FOR ESTABLISH THE ABSENCE OF VOLTAGE
Follow these simple steps for establish the absence of voltage:
Before starting work on the equipment, it shall be isolated from the mains supply. This disconnection
shall always be checked by visual inspection. Further precautions shall be taken to ensure that the
mains supp!y cannot be restored whilst work is being carried out. After the mains supply has been
disconnected, all other lines such as control, interlocking and modulation lines shall be disconnected
if they carry dangerous voltages. Moreover, the antenna or the antenna transmission line shall be
disconnected from the antenna terminal device to prevent the introduction of dangerous voltages
due to antenna pick-up. When disconnection of the antenna or antenna transmission line is not
possible, other suitable precautions shall be taken, for example, earthing, when necessary at several
places, to esablish absence of voltage. These earthing connections shall be very short compared
with the wave-lenght.
Capacitors which are connected to a circuir isolated frcm its supply shall be discharged and have
their terminals permanently short-circuited and the casing earthed during the whole period of the
work.
The electrical charge retained by electrical machinery when stopped may, in certain cases, be
sufficient to cause a severe shock. This shall be taken into account when making connections to an
apparently "dead" machine. Therefore all machinery shall be discharged and earthed using an
adequately insulated lead for this purpose. The discharge operation shall be repeated several times.
Before any maintenance work is carried out on automatic or remote controlled equipment, the
remote swithching circuits shall be made inoperative.
1.4.1 PROCEDURE FOR DETERMINATION OF THE ABSENCE OF VOLTAGE
After the equipment has been isolated according to the standard EN60215, the absence of voltage shall be
determined at the work place. This may be done by the use of voltage indicators, measuring instruments,
glow discharge lamps for indicating radio-frequency voltage or other suitable means.

1.5 FIRST AID IN CASE OF ELECTRICAL SHOCK
If someone seems unable to free himself while receiving an electric shock, turn power off before rendering
aid. A muscular spasm or unconsciousness can make a victim unable to free himself from the electrical
power.
If power cannot be turned off immediately, very carefully loop a length of dry non-conducting material (such
as a rope, insulating material, or clothing) around the victim and pull him free of the power. Carefully avoid
touching him or his clothing until free of power.
1.5.1 EMERGENCY RESUSCITATION TECHNIQUE
Step 1
Check the victim for unresponsiveness. If there is no response, immediately call for
medical assistance, and then return to the person.
Step 2
Position the person flat on their back. Kneel by their side and place one hand on the
forehead and the other under the chin. Tilt the head back and lift the chin until teeth
almost touch. Look and listen for breathing.
Step 3
If not breathing normally, pinch the nose and cover the mouth with yours. Give two
full breaths. The person's chest will rise if you are giving enough air.
Step 4
Put the fingertips of your hand on the Adam's apple, slide them into the groove next
to the windpipe. Feel for a pulse. If you can not feel a pulse or are unsure, move on
to the next step.
DO NOT TOUCH VICTIM OR HIS CLOTHING BEFORE
POWER IS DISCONNECTED OR YOU CAN ALSO
BECOME A SHOCK VICTIM
Screen Service SDT ARK 1 ECHO General information
Jan, 2012 v 1.ATSC_FCC Page 1 - 6
Step 5
Position your hands in the center of the chest between the nipples. Place one hand on
top of the other.
Step 6
Push down firmly two inches. Push on chest 15 times.
CONTINUE WITH TWO BREATHS AND 15 PUMPS UNTIL HELP ARRIVES.
1.5.2 TREATMENT FOR BURNS
Continue treat victim for electrical shock.
Check for points of entry and exit of current.
Cover burned surface with a clean dressing.
Remove all clothing from the injured area, but cut around any clothing that adheres to the skin and leave
it in place. Keep the patient covered, except the injured part, since there is a tendency to chill.
Splint all fractures. (Violent muscle contractions caused by the electricity may result in fractures.)
Never permit burned surfaces to be in contact with each other, such as: areas between the fingers or
toes, the ears and the side of the head, the undersurface of the arm and the chest wall, the folds of the
groin, and similar places..

2.1 GENERALITY
Propagation is a critical issue in ATSC / Mobile TV broadcasting.
In this contest, the use of repeaters for digital TV broadcasting becomes a key issue for commercial
terrestrial distribution of digital TV.
In addition, 8VSB signal characteristics avert well known adjacent channel interference problems of
analogue TV broadcasting. This leads to the SFN network planning: a single frequency is used all over the
coverage territory, increasing spectrum efficiency.
Therefore, in digital TV SFN netwotrks iso-frequency repeaters are needed. An On-channel repeater is,
basically, a radiofrequency repeater that receiver and transmits using the same frequency.
Traditional On-channel repeater use is limited by a hard design constraint: coupling between transmitter and
receiver antenna limits the allowed maximum gain for the on-channel repeater, leading to a reduction of the
coverage area: a traditional on-channel repeater installation is only possible if hard isolation conditions are
complied.
A on-channel repater, with coupling echo cancellation system, allows operations at higher power levels
under normal tower isolation conditions.

2.6 FUNCTIONAL DESCRIPTION
2.6.1 GENERAL
The ARK 1 receives on its inputs An RF signal or four MPEG-2 Transport Stream in serial ASI format.
The RF input signal is converted into a standard 36 MHz IF frequency by a fully agile down converter.
This signal is digitally filtered, elaborated, precorrected and then presented at 997 MHz to the channel
converter.
The channel converter provides to generate the final frequency in a fully agile mode.
The LO with a very low phase noise is locked to the 146 MHz high stability reference.
Reference signal coming from GPS board allow precision offset
The switching power supply module generates the following voltages to feed the different circuits: +32 V,
+ 24V.
2.6.2 RF AMPLIFICATION
The signal coming from the agile up converter goes to the RF amplifier section. The RF amplification is done
by class A and AB stages.
Out of the final stage, the RF signal passes through a directional coupler. The directional coupler detects
samples of direct and reflected power and passes this information to the check function

3.4.7 Network Synchronization parameters setting
Four Network Synchronization modes are available:
Multi Frequency Network mode using local parameters (MFN):
The transmitter is not synchronized with any network. No input MIP is
needed and Clock Reference can be internal.
Multi Frequency Network mode using MIP parameters (MFN MIP):
The transmitter is not synchronized with any network but MIP sets the
modulation parameters. Input MIP is needed and Clock Reference can
be internal.
Single Frequency Network mode (SFN): The transmitter is
synchronized with a Network of transmitters on the same frequency.
MIP is needed and Clock Reference must be external or GPS.
Single Frequency Network mode using local parameters (SFN
Local): The transmitter is synchronized with a Network of transmitters
but for testing purposes the modulation parameters are set locally.
Input MIP is needed for 1PPS synchronization and Clock Reference
must be external or GPS.

3.5 PRE-CORRECTION TOOL
The ARK1 system provides a pre-correction tool for both Module&Phase and AM/PM output
signal pre-correction.
Remember to save curves changing before closing the connection to port 5000. At every
working session open
Note: the operation of uploading and downloading pre-correction curves moves a large
amount of data from and to the device. The use of these tools over low badwidth, not stable
or high distances netwoks could cause frequently time-out disconnections and it is not
reccommended.
3.5.1 Module&Phase
Click on MOD. PHA. button icon, highlighted in the nex figure, to modify the complex filter
curves for linear pre-correction.
Figure 14. Phase and module window
Screen Service SDT ARK 1 ECHO Operations
Jan, 2012 v 1.ATSC_FCC Page 3 - 52
This tool provides two grids for the drawing of:
Module of the filter’s curve.
Group Delay of the filter’s curve.
The two curves are used to calculate the linear pre-correction coefficients. The curves are
drawn by the interpolation of 1024 points referring to the points inserted and using a linear or
polynomial interpolation algorithm.
Knob points can be added with a left-click of the mouse on the grid and deleted with a right-
click, drag and move a point to change the curve.
Each coefficient variation, due to curves change, is saved in the FPGA “runtime” memory
registers and dynamically changes the device’s output.
The tool is prevented to send an “overflowing” amount of data to the device: curve changes
will be applied only when the mouse button is released.
In the module grid, the red curve is used to monitor the current module curve calculating and
saving. The last saved coefficients are locally downloaded from the FPGA runtime memory
registers in order to redraw the curve.
Click two times the right mouse button on the grid to open the zoom menu. The “H” options
are used to horizontally zoom (x01,x02,x04,x08,x16). The “V” options are used to vertically
zoom (x01,x02,x04).
During the saving actions are created two nonlinear pre-correction files:
*.dlin files: files containing digital coefficients values for Digital-IF linear pre-
correction curves.
*.alin files: files containing analog coefficients values for ATSC Re-modulator linear
pre-correction curves.
The following buttons allow the management of linear pre-correction files and the
management of the connection to port 5000:
Save: used to save in the device memory the current curves setting. The previously
saved file will be overwritten except in the evet that no files have been saved before;
in this case a dedicated window appears in order to let the user name the new file.
Save as: used to save in the device memory the current curves setting. The
previously saved file will be overwritten with a new name. in the evet that no files
have been saved before, a new file will be created.
Read file: used to reload the last saved file.
Export: used to download pre-correction files on the user PC. A browser window
allows the selection of the saving path.
Release: release the connection in order to allow others remote machines to
connect to port 5000 (refer to Connection to port 5000 paragraph).
Files are separately managed in analog and in digital AGC mode.
3.5.2 AM/PM

Two main actions are possible in this section:
AM/AM and AM/PM curve drawing: used to change the AM/PM pre-correction
coefficient.
AM/PM pre-correction files management: used to open or save AM/PM pre-
correction setting file.
AM/AM and AM/PM curves are specific for each power range of each output channel.
The two curves are used to calculate the AM/PM pre-correction coefficients. The curves are
drawn by the interpolation of 1024 points referring to the points inserted and using a linear or
polynomial interpolation algorithm.
Knob points can be added with a left-click of the mouse on the grid and deleted with a right-
click, drag and move a point to change the curve.

3.5.3 Connection to port 5000
The connection to port 5000 is performed every time a pre-correction tool is opened through
Mod.Pha. button and AM/PM button, from Java interface,. The pre-correction tool opens and
keeps busy the connection to port 5000 till the connection releasing
The connection to this port precludes the possibility of:
programming the device;
allowing more than one user, the very same one that is keeping busy the connection,
to open the pre-correction tools.
The Release button comes through these limits. It closes the connection to port 5000, close
the Mod.Pha. / AM/PM window and opens the General window. Once clicked the Release
buttons and before quitting the pre-correction tool, three options are provided:
Continue: continue without saving;
Save and Release: save and continue;
Cancel: cancel the request of releasing the connection.

3.6 Channel filter & complex filter
Click on Filter button icon, highlighted in the nex figure, to access the channel and complex filters
window.
Figure 17. Channel filter & complex filter window
Use the Filter window to manage and monitor channel and complex filters.
To understand the behavior of the Echo’s Channel Filter, a brief explanation is needed. The
Fold-back mode is an algorithm that makes use of 3 thresholds, determined by the
characteristics of the system (receiver and transmitter’s antenna front and back gains), to
calculate the optimal range of the transmitter’s output RF power that results in controlled
echo level on the receiver side antenna. The so introduced thresholds are:
Threshold Fold Back Alarm: individuates the level of the transmitter’s output RF
power that determines an uncontrollable echo level on the receiver side antenna.
Threshold Fold Back Down: individuates the upper limit of the optimal range of the
transmitter’s output RF power. When the “Module” value is higher than this
threshold, the controller decreases the output RF power.
Threshold Fold Back Up: individuates the lower limit of the optimal range of the
transmitter’s output RF power. When the “Module” value is lower than this threshold,
the controller increases the output RF power.
Screen Service SDT ARK 1 ECHO Operations
Jan, 2012 v 1.ATSC_FCC Page 3 - 57
It follows that:
Thr. FB Alarm > Thr. FB Down > Thr. FB Up.
The “FPGA Gain” value results from the comparison of the “Module” value with the
thresholds:
0: when “Module” is lower than FB Up.
1: when “Module is higher than FB Down.
2: when “Module” is comprised between FB Up and FB Down.

The Alarm window allows the setting of alarm masks and the monitoring of alarms status.
Use alarm masks to select how and which alarm have to be notified.
Masks are organized in columns. The sixteen columns represent sixteen destinations of each
alarm condition:
GUI: the selected alarms status is notified on the Java alarm page icon.
LCD: the selected alarms status is notified on LCD display lighting the alarm button
and listing the alarms in the Alarms menu (refer to Alarms Menu paragraph).
Event: the selected alarms status generate an alarm event that will be logged in
the event memory (refer to Events paragraph).
R0…R3: the selected alarms switch on the corresponding relay.
T0…T7: the selected alarms generate the corresponding trap messages (refer to
Network paragraph to set destination IP addresses).
RF: the selected alarms switch off the RF output. The RF mask is almost entirely
fixed in order to avoid board damages or malfunctioning.
In the Alarms window, when an alarm condition occurs, the relative alarm is red highlighted.
The Total check box enables all alarms-to-masks associations.
Remember to enable the RF Off alarms mask of ATSC alarms while working in Tx ATSC mode.

3.13 SNMP – Simple Network Management Protocol
The SNMP model assumes the existence of managers and agents. A manager is a
software module in a management system responsible for managing the device. An
agent is a software module in a managed device responsible for maintaining local
management information and delivering that information to a manager via SNMP. A
management information exchange can be initiated by the manager (via polling) or by
the agent (via trap).
Interaction between a user of board management and the board management software
takes place across a user interface. Such an interface is needed to provide users with a
monitoring and controlling tool in order to allow some parameters to be viewed or set
locally.
The operations that are supported in SNMP network management are the alteration and
inspection of variables. Specifically, three general-purpose operations may be performed
on scalar objects:
Get: a management station retrieves a scalar object value from a managed
station.
Set: a management station updates a scalar object value in a managed station.
Trap: a managed station sends an unsolicited scalar object value to a
management station.
Management information accessible via SNMP is maintained in a management
information base (MIB) at each manager and agent node.
On manager side, SDTX ECHO management system has been tested with MG-SOFT as
MIB Browser; besides compatibility with any other MIB browser is assured.
The following MIB libraries are required for the SNMP management of the equipment:
SCREENSERVICE-SCB-BROADCASTING-MIB.my;
echo_0_1.MY.
Compatibility tested and assured with SNMP version 1 and 2.

3.18 Configuring alarms masks
The echo_Alarm leaf allows the monitoring of alarms status, the setting of alarm masks and
thresholds.
Use alarm masks to select how and which alarm have to be notified.
Figure 36. Configuring alarms
There are six families of alarm masks:
echo_AlarmJavaEnable: the selected alarms status is notified on the Java alarm
page icon.
echo_AlarmFrontPanelEnable: the selected alarms status is notified on LCD
display lighting the alarm button and listing the alarms in the Alarms menu (refer to
Alarms Menu paragraph).
echo_AlarmEventsEnable: the selected alarms status generate an alarm event
that will be logged in the event memory (refer to Events paragraph).
echo_AlarmRelay: the selected alarms switch-on the corresponding relay.
echo_AlarmTrap: the selected alarms generate the corresponding trap message.
echo_AlarmRfEnable: the selected alarms switch off the RF output. The RF mask
is almost entirely fixed in order to avoid board damages or malfunctioning.
Each alarm mask is a 32 bits word and each alarm represents one bit (0: Off, 1: On). Set the
decimal value corresponding to the mask you want to activate in the relatve leaf. The following
table shows the bit-to-alarm association.

3.19 Traps
While a management station can poll, at fixed time interval, all the agents it knows for some key
information, each agent is responsible for notifying the management station of any alarm
condition. These events are communicated in SNMP messages known as traps.
The following parameters should be set in order to correctly configure traps:
SNMP Agent Port: 162.
SNMP Agent Transport protocol: IP/UDP.
Variable
o OID: 1.3.6.1.4.1.21678.200.13.
o Value(gauge): 32 Bit
3.19.1 Configuring traps
Use Java (refer to Network and Alarms paragraphs for further information) or SNMP user
interfaces to configure traps.
The configuration of traps is performed through the setting of a trap alarm mask, by means of
leaves housed in the echo_AlarmTrap node (refer to Configuring alarms paragraph), and
through the setting of the destination IP Address of the receiving management stations, by
means of leaves housed in the echo_Network node as shown in next figure.

3.20 AUTOMATIC FREQUENCY CONTROL
The Television Broadcasting through countrywide transposers networks requires special care to
avoid too high frequency drift errors.
The Automatic Frequency Control is highly recommended for transposers chains. The following
figure illustrates an example of when the AFC might be used to stop the overwhelming increase
of such errors.
Figure 39. TROVA NOME
The Automatic Frequency Control in ARK1 devices is software defined.
Most of the frequency drift errors could be avoided by means of a stable frequency reference,
such as GPS, but since it is not always available, the ARK1 AFC makes it possible to
compensate frequency jitters owing to each previous transposer.
Frequency compensation of analog input signals is performed through a proprietary algorithm
that, filtering the input video carrier, allows the control loop to extract frequency jitter information
from the input RF phase deviation.
The frequency error adjustment slows down within 3 Hz; it takes about 2 minutes to fulfil the
correction.
Frequency resolution: 1Hz.
Maximum frequency compensation: 4,000,000 Hz.
Frequency compensation of digital input signals is carried out through frequency jitter
information coming from STV0362 receiving the HP Transport Stream.
Frequency resolution: 1kHz.
Maximum frequency compensation: 83kHz.
Due to the Symbol Rate error compensation of the frequency measure algorithm of STV, digital
AFC can work properly only with 0ppm Symbol Rate errors in the input signal.

Appendix A. Standalone/Driver working modes
Two different working modes are provided:
Stand-alone: the device works in stand-alone mode. The system configuration can be
totally set through user interfaces. Pre-correction curves are automatically selected
according to channel and power range.
Driver: the device works in a driven system. The system configuration cannot be totally
set through user interfaces. Some settings are disabled on the user interfaces in order
to be driven by serial interface commands. Pre-correction curves are not automatically
selected according to channel and power range, but the selection is manually performed
through serial interface commands.
The following table lists the commands, specific to each system interface, which must be
enabled or disabled while working in Driver mode.
N.B. Diver mode is a specific working mode available and used only in N+1 configuration
systems.
