Screen Service SDT ARK 1 ECHO General information Jan, 2012 v 1.ATSC_FCC Page 1 - 2 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.
Screen Service SDT ARK 1 ECHO General information Jan, 2012 v 1.ATSC_FCC Page 1 - 3 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.
Screen Service SDT ARK 1 ECHO General information Jan, 2012 v 1.ATSC_FCC Page 1 - 4 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.
Screen Service SDT ARK 1 ECHO General information Jan, 2012 v 1.ATSC_FCC Page 1 - 5 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 Purpose and planning Jan, 2012 v 1.ATSC_FCC Page 2 - 3 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. 2.2 INTRODUCTION SDT ARK-1 ECHO is a Multi-standard Television Transposer. Based on Software Defined technology, SDTX ECHO allows the definition of different operative modes on the same hardware platform. At the state of the art SDT ARK-1 ECHO has the following possible working modes:  Analog Television Heterodyne Transposer;  Digital Television Heterodyne Transposer;  Digital Television Heterodyne Transposer with echo canceller;  Re-broadcasting ATSC Modulator. Analog and Digital Television Heterodyne Transposers receive and re-transmit Analog or Digital TV signals allowing the software setting of input and output channels. Re-broadcasting ATSC Modulator receives and de-modulates ATSC signals and re-modulates them. Auxiliary inputs and outputs allow to import and export TS contents on ASI and GBE interfaces. The single software controller allows the switching between working modes and different settings for each operative mode using the same platform. A brief description of the main features and potentialities of each operative mode follows. 2.2.1 ANALOG/DIGITAL TELEVISION HETERODYNE TRANSPOSER Heterodyne Transposer with Digital Filtering at Intermediate Frequency for Analog and Digital Television standards.

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

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.

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 Click on AM/PM button icon, highlighted in the nex figure, to access the pre-correction 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.

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.

The OID of the SDTX ECHO system is:  screenservice_SDTx Echoc: 1.3.6.1.4.1.21678.200 iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).screenservice(21678).screenservice_echo(200) 3.17.1 SNMP tree structure The SNMP tree structure is shown in the previous figure, after the node screenserviceBroadcasting there is the node that specifies the device typology. The screenservice_SDTx Echo tree has 12 nodes and 1 leave. The nodes are:  echo_SystemInfo: global description of the system.  echo_Mode: shows and manages board modes.  echo_Input: shows and manages inputs. Note: In Echo_STV0 and Echo_STV1 nodes are housed the statistics of the digital RF signal. STV0 and STV1 are the two IF demodulators for the HP and LP streams respectively.  echo_Mip: shows MIP modulation parameters.  echo_SettingsATSC: shows and sets local modulation parameters.  echo_Output: shows and manages the output.  echo_HW_monitor: shows the amplifier status.  echo_Gps: shows the collection of live data from GPS receiver.  echo_Clock: shows and sets 10MHz and 1PPS source.  echo_Network: shows and sets network parameters.  echo_Alarm: shows and manages system alarms.  echo_Config: allows the management of the machine configuration.  echo_TrapAlarm: is the OID used in the trap message.

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.

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.

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.

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.
