231.4 OPERATIONAL DETAILSAll the sections of the ATSC TRANSMITTER, as showed in the block diagram above, are described in thissection in order to give the user a general understanding of the operations of the equipment.1.4.1 TS INPUT MANAGEMENTThe ATSC TRANSMITTER is equipped with 2 ASI inputs and 2 SMPTE-310M inputs. Each input standardis available with two inputs in order to enable redundant operation for the transport stream input. You candecide to operate with SMPTE input or with ASI input depending on your network interfacing needs. Ineither case a complete redundancy is guaranteed thanks to a duplicated input.The ATSC transmission scheme is built over a very stable and accurate data stream clock. The SMPTE-310M data clock shall have the exact standardized clock frequency. The modulator module takes itssynchronization from this input data stream to be able to recover the same clock frequency. If an externalclock reference is used (10 MHz), the global clock synchronization might be plesiochronous (i.e. not perfectsynchronization between the multiplexer clock and the modulator reference clock). In that case, it isrecommended to enable the "bit rate adaptation" on the ATSC TRANSMITTER.When this mode of operation is enabled, the input processing module discards or inserts Null Packets in orderto adapt the MPEG-TS input bit rate to the precise bit rate defined by the ATSC recommendation. PCR re-stamping is then executed accordingly.The switching is not expected to be seamless. However, in case of feeding the exact data stream on bothinputs (Primary & Secondary), then the ATSC TRANSMITTER performs a seamless switching from one tothe other input. Switching is always performed on a packet basis.The user may enable or disable the automatic mute when an error on the SMPTE-310M or on the ASI inputis detected. The delay for the detection of the lost of SMPTE-310M is 1 second from its occurrence. In casethe user disables the automatic mute, null packets are inserted in order to feed the modulator section with theexact ATSC bit rate.Two test modes are available for testing and alignment procedures. The 23-bit PRBS test mode generates apseudo-random data sequence in order to produce a correct output spectrum even in absence of a valid TSinput. The single-tone test mode produces a sinusoidal output useful for frequency converters alignment. Thetest modes are useful only for testing purposes and shall not be used for real broadcasting operation.- Redundancy managementWhen set in Automatic Switching mode (default), the input management unit automatically detects the presenceof a valid MPEG Transport Stream (MPEG-TS) on the main or auxiliary inputs. If no valid MPEG-TS flow
24is detected, the unit switches automatically to the other input. The periodic occurrence of the Sync byte in theMPEG-TS packets is used to decide if a MPEG-TS flow is valid or not. If the user chooses to operate inManual switching mode then he has to force which input is active.- Reed Solomon FECIf the ASI incoming inputs (note: only for ASI input mode) include the Reed Solomon codes (204 bytespackets), the module performs the error correction thanks to the 16 RS bytes.- Bit rate adaptationWhen operating in ASI input mode, the input management unit can perform an automatic bit-rate adaptation,if required. When this mode of operation is activated, the unit automatically removes and/or inserts null packetsin order to adapt the incoming ASI bit-rate to the exact bit-rate defined by the ATSC recommendation. PCRrestamping is then executed in real time.- SquelchThe RF output signal can be muted if one of the following conditions occurs:- a hardware problem is present (for example, the amplifier temperature is too high, the modulator does not communicate with the controller and so on);- an error in the input signals is present (input TS missing and Mute on input error feature enabled).In the first condition, the output is muted to protect valuable internal parts of the equipment and/or save power. In thesecond condition, the output is muted because the signal is most probably unusable by receivers. This muting actionis known as Squelch.In a dual drive or 1+1 transmitter, the changeover control unit should discriminate if the output power reduction iscaused by a hardware problem (the changeover takes place) or by an input signal problem (the changeover is notperformed). The user can change the meaning of the digital output in the TLM port choosing "Alarm" (useful tointerface a custom remote control system) or "Squelch" (useful to interface a changeover control unit).1.4.2 SYNCHRONIZATION AND CLOCKSThe ATSC TRANSMITTER includes its own clock and synchronization generator. A high stability 10MHzVCTCXO provides the internal clock reference to the clock system of the digital processing section of theequipment. An external 10MHz reference may be used if a higher stability is needed, or if there is a need tolock the modulator processing clock or the output carrier frequency to an external reference (i.e. operation infrequency offset mode).In special cases, the 10MHz internal clock may be locked to the system clock embedded into the ASI/SMPTE input signal. In this case, you can not enable the Bit-Rate Adaptation function and the input bit ratehas to be the exact ATSC bit-rate (19.392658Mbit/s). If the ATSC TRANSMITTER is set up to operatewith either of the two external references (from ASI/SMPTE input or from the external 10MHz reference), itwill automatically switch to the internal reference if the external reference is missing. The switching from the
25external 10MHz reference to the 10MHz internal clock is totally seamless. The processing clock of the numericalsection of the ATSC TRANSMITTER is always locked to the internal or to the external 10MHz reference.1.4.3 OUTPUT SIGNALThe ATSC TRANSMITTER output signal is available at the output labelled RF OUT on a 50Ω N-typefemale connector. The frequency of the output signal can be set in the VHF and UHF bands, depending on themodel type. The frequency can be set by choosing the standard/channel/offset combination (for example,UHF standard, channel 45 and offset 0Hz) or by choosing directly the center frequency of the output signal.An attenuated version of the output signal is available at the RF Monitor terminal located on the front panel ofthe equipment. The maximum nominal output level is 5W RMS, the output power level can be controlled inAGC (Automatic Gain Control) mode or in manual mode and can be adjusted by the rotating knob locatedon the front panel. The output signal may be muted either manually by the user or automatically depending onsome given conditions. The mute can be direct (abrupt muting) or progressive (linearly decreasing function).1.4.4 NON-LINEAR PRECORRECTIONAny solid-state or tube power amplifier will produce intermodulation distortion when fed by the ATSC 8-VSB signal. Non-linear precorrection is used to compensate the effects of these distortions in order to radiatea signal with the maximum possible MER value.The ATSC TRANSMITTER is able to perform non-linear precorrection over a 20MHz bandwidth. For thispurpose, two tables (AM-AM and AM-PM) of maximum 16 taps are used by the modulator.The AM-AM precorrection table defines the AM-AM curve that will be applied to the output spectrum. Foreach tap, the abscissa can be defined from -12dB to +12dB by 0.05dB step and the ordinate can be definedfrom -6dB to +6dB by 0.05dB step.The AM-PM precorrection table defines the AM-PM curve that will be applied to the output spectrum. Foreach tap, the abscissa can be defined from -12dB to +12dB by 0.05 step and the ordinate can be definedfrom -25 degrees to +25 degrees by 0.2 degrees step.Up to 10 non-linear precorrection curves (10 AM-AM and 10 AM-PM tables) can be downloaded andsaved into the equipment memory. For each curve a 10-characters name is associated. By using the local orremote control it is possible to disable the non-linear precorrection at all or activate one of the saved curves.Besides the 10 customizable curves, a non-customizable "Null" curve is always available: the AM-AM andAM-PM tables of this curve are filled by zeros.1.4.5 LINEAR PRE-CORRECTIONAny output cavity filter will produce amplitude and group delay distortion over the ATSC 8-VSB signal
26generated by the transmitter. Linear precorrection is used to exactly compensate these distortions in order togenerate a signal which is maximally flat both in amplitude and group delay. The ATSC TRANSMITTER isable to perform amplitude and group delay correction over the full spectrum of the output signal.The linear precorrection is a factory procedure, so the equipment is delivered with the optimal linear precorrectioncurve already operating.By operating on the front panel user interface, the user may decide to switch off or switch on the linearprecorrection curve stored by the Elettronika production department.1.4.6 CONTROL OF THE EQUIPMENTThe ATSC TRANSMITTER can be controlled by means of a user-friendly LCD graphical interface with asingle rotating knob for the menu navigation and for the selections or remotely through a RS232, RS485 orTELEMEASURES port. The functions of the local and remote control are:- Setting the operating mode of the ATSC TRANSMITTER and the associated parameters. All these parameters are stored in a local memory, so the previous operating mode is automatically restored each time after a power cycle.- Monitoring the status of the equipment.- Recording events and alarms.- Firmware upgrades.- Digital Precorrection through RS232 port and dedicated PC software interface.1.4.7 TEST MODESTwo test modes are available, to be used only for laboratory or field test. The test modes are directly accessiblefrom the user menus and are:1) PRBS Sequence: the ASI/SMPTE input signals are ignored and a 23-bit PRBS sequence replaces the in- put payload of the MPEG-TS packets. This test allows measurements on the modulated signal without the need of a valid ASI/SMPTE input signal.2) Single Tone: the normal 8-VSB output spectrum is switched off and replaced by a sinusoidal output useful for frequency converters alignment.Note: If test mode 2) is active, the ATSC TRANSMITTER does not generate a valid ATSC 8-VSB signal.1.4.8 POWER HANDLINGAfter the ATSC TRANSMITTER is powered on, it starts radiating a valid ATSC 8-VSB signal within a shorttime. The maximum initial power-on delay is about 20s as factory default value. Any modification of this initialpower-on delay is to be done with the support of the Elettronika Customer Service.
27If a valid MPEG-TS signal is received over one of the ASI/SMPTE inputs, then the equipment will immediatelygenerate the signal on the RF output. In absence of a valid MPEG-TS signal the equipment can be set to bemuted or not.Enabling the muting function is possible by the user menus, as explained in the Menu Management section ofthe present manual.All the working parameters of the ATSC TRANSMITTER are stored into a non-volatile memory in themodulator section, so that there is no need to restore the parameters after a power off/on cycle.The power handling is characterized by 3 states: MUTE, POWER UP and POWER ON.z MUTE (POWER LED off, fan off): the internal amplifier is switched off by inhibiting the RF transistors gate.z POWER UP (POWER LED blinking, fan on): the internal amplifier is switched on and the output power, starting from -3dB to the final level, is slowly increased following a linear ramp law.z POWER ON (POWER LED on, fan on): the internal amplifier is switched on (normal working operation).Moving from MUTE to POWER ON state (for example, after switching on or when an active alarm disappears)is performed by moving through a temporary POWER UP state. Instead, moving from POWER ON toMUTE state (for example, when a serious alarm occurs or the ASI/SMPTE inputs are corrupted or absent)is immediate.1.4.9 ALARMS AND AUTOMATIONThe ATSC TRANSMITTER is fully protected against any malfunctioning event that could damage the expensiveinternal components. The user should clearly understand what happens in presence of alarms and warnings,in order to face these situations properly and reduce the inactivity time.In case of any alarm condition, the ALARM LED on the front panel lights up and a bell icon appears in thestatus bar of the display. When the alarm condition ceases, the ALARM LED is turned off and the bell iconstarts blinking, in order to show that an anomaly occurred since the last visit to the log. To know the detailsabout the alarm event (for example the time and date of its occurrence), the log menu can be used. Once theuser enters the log screen, the bell icon disappears. When you note an active alarm (the bell icon is shown andnot blinking and the ALARM LEDis on), go to the ALARM screen to see which alarms are present. For certain dangerous situations, the ATSCTRANSMITTER immediately switches off the output power, by acting on the RF power transistors gate, inorder to save the internal parts from an unrecoverable damage. When the alarm disappears, the power isautomatically switched on again. Once the output power has been inhibited for 5 times, the ATSCTRANSMITTER goes into "Lockout" state: the power remains off until the user resets the Lockout condition,or switches the equipment off for repair. After one hour from the last alarm and without the Lockout condition,the Lockout counter is automatically cleared. The list of the automatic interventions in case of anomalies canbe found below.
28z Amplifier VoltageAn amplifier power supply voltage alarm occurs when the monitored voltage is outside the nominal level±10% range. The nominal voltage level is a factory setting (usually, 28V). This alarm does not trigger apowering off of the output signal. If the monitored voltage is near 0V, most probably the fuse located near thepower amplifier stage is burned.z Amplifier CurrentAn amplifier power supply current alarm occurs when the monitored current drained by the amplifier is 20%above the nominal level. The nominal current level is a factory setting. This alarm does not trigger a poweringoff of the output signal.z Amplifier TemperatureThe temperature is monitored on the hottest point, located near the power amplifier stage on the cooling heat sink.If the fans work well, and the ambient temperature is inside the working conditions limits, all of the internal partsshould reach safe temperature levels. In some circumstances (for example, when a fan is blocked or damaged), thetemperature may increase too much, and some internal components may break. In order to avoid this unpleasantsituation, a temperature alarm occurs when the temperature is over a maximum threshold (75°C). This alarmtriggers an immediate powering off of the output signal and an increase of the lockout counter.The power will be switched on again only when the temperature goes below a second threshold, lower than the first(70°C).z Forward and Reflected PowersA forward or reflected power alarm occurs when the relevant monitored power level is over a threshold(factory setting). Both alarms trigger an immediate powering off of the output signal and an increase of thelockout counter.You can see the levels of the power thresholds in the Amplifier menu (see the Menu Management paragraph).z Power supply voltages (+5V, +12V, -12V)Besides the amplifier power supply voltage (+28V), the ATSC TRANSMITTER uses three additional mainvoltages: +5V, +12V, -12V. These voltages are continuously monitored by the control system and any variationabove 10% of the nominal value generates an alarm condition. This alarm does not trigger a powering off ofthe output signal.z No communication with the modulatorThe 8-VSB Modulator module continuously communicates with the control system. If this communicationfails, the control board triggers a "No communication" alarm.This is a serious malfunction that must be solved as soon as possible.In presence of a no communication alarm, the control system is not able to know the working condition of themodulator (for example, the modulated output signal level), so it inhibits the power amplifier stage and theoutput power is brought to zero level.
29z External reference alarmWhen external or ASI/SMPTE reference is set, the modulator continuously monitors the presence of suchreference. If it is not able to find a correct signal, it automatically switches to the internal reference. In thissituation, an external reference alarm is triggered. This alarm does not trigger a powering off event. See theSynchronization and Clocks paragraph for more information.z ASI/SMPTE inputs alarmThere are several conditions related to input streams that could trigger an alarm, depending on the workingconditions. They are:- MPEG-TS synchronization missing;- uncorrected input packet (only in 204 RS coded mode with ASI input mode);- bit rate underflow/overflow (only if bit rate adaptation is performed).The above conditions trigger an alarm only for the input which is currently used by the ATSC TRANSMITTER.1.4.10 AGC: IMPLEMENTATION AND DETAILSThe use of external AGC helps the ATSC TRANSMITTER to maintain stable the output power of a high-power transmitter. With a menu setting (see the Menu Management paragraph) you can choose amongstabilizing the output power of the exciter (external AGC disabled) or stabilizing the output power of a high-power transmitter (external AGC enabled). In this case a proper cabling between the ATSC TRANSMITTERand the high-power amplifier stage is necessary. The cable (AGC cable) shall be connected to the TLM portof the ATSC TRANSMITTER on one side. In the following table the three signals and pins used in the TLMport are listed. The pinout connection of the cable depends on the specific amplifier used. Refer to youramplifier user's manual to find the port and pins of the corresponding signal.PIN I/O DESCRIPTION4 I Forward Power (0-5V)5-GND8 I Alarm (GND=Alarm / Open=Normal)The AGC goal is to maintain the output power stable. Output power in fact can change due to the increase ofthe amplifier temperature. Note that when you change the operating frequency the output power changes dueto the different gain at different frequency, but this change is not stabilized by the AGC algorithm. The transmitterpower to be stabilized is read from TLM port.To keep the power stable, the AGC changes the power gain of the ATSC TRANSMITTER.The AGC algorithm is based on the acquisition of the optimal output power level, stored when you confirm the
30output power level in the Power menu (see the Menu management paragraph) and the use of 4 thresholdsas below:____action threshold ________goal threshold ___________optimal power value ________goal threshold____action thresholdThe distance of the thresholds from the optimal value is of ±20mV and ±30mV measured as monitor voltage.The AGC changes the output power to bring the power from the amplifier inside the goal thresholds range.When this goal is achieved, the AGC stops until the power goes outside the action thresholds range.The AGC is stopped immediately (output power remains blocked to the value reached at the moment inwhich the AGC stops) when one of the following conditions occurs:z RF output is muted for an alarm condition or user setting;z the AGC is chosen as external but the amplifier stage triggers an alarm;z the ATSC TRANSMITTER output power is too low;z the AGC has corrected the output power too much.In order to simplify the understanding of the AGC behaviour, the status of the external AGC is written in thePower menu (Ext AGC Status parameter). The possible statuses of the AGC are listed below.z Disabled: external AGC is disabled.z Idle: external AGC is stopped (for example, during the slow increase of the power immediately after swit- ching on the equipment).z Low Set: external AGC is stopped because external power reading was too low when the nominal output power has been chosen.z Alarm: external AGC is stopped because an alarm signal from the power amplifier stage is active.z Locked: the transmitter output power has reached the desired level.z Max/Min: external AGC is stopped because the power correction is too high.z Pull Up/Down: external AGC is moving the power level up or down.Warning! When changing from AUTO to MANUAL power control mode, the external AGC will be disabled.

321.14.11 LOGThe ATSC TRANSMITTER is provided with an internal non-volatile memory used to store up to 200 eventsin a log. For each event, the date, time and a description are stored in order to help the user in understandingthe sequence of the events and the cause of each alarm.The log can be viewed locally on the display (see the LOG screen in the Menu Management paragraph)or by remote. It is possible to clear the log contents only locally.The events are organized from the last one: the first event in the log is the last that happened. The second is theprevious event compared to the first, and so on.When the log is full (i.e., 200 events are stored), the new events will replace the older ones, like in a FIFO(first in/first out) queue.The type of events that can be stored in the log are:z Power supply on from mains voltagez Mute settings (automatic/manual) changedz Remote/local control changedz Lockoutz Amplifier voltage alarmz Amplifier current alarmz orward power alarmz Reflected power alarmz Temperature alarmz Power supply voltage (-12V, +12V or +5V) alarmz Modulator no communication alarmz External reference alarmz ASI/SMPTE inputs related alarms

383.1 LOCAL CONTROLA large number of options of the ATSC TRANSMITTER can be easily and intuitively controlled through thehuman-to-machine interface on the right side of the front panel. This is composed by a graphic display, aclickable knob and three LEDs.Right after switching on, a screen showing the initialization process appears on the display. During this time thecontroller checks the good communication among internal parts of the equipment.3.2 LEDsNear the display three status LEDs allow to gather information concerning the general status of the systemwithout having to look at the display.Their meaning is explained in the table below.LED COLOUR DESCRIPTIONON GreenThe ON LED is lit when the power is on. It blinks duringthe power increase stage. It is off if the output is muted(see the Power handling paragraph)REMOTE Yellow The REMOTE LED is lit when the remote control isenabledALARM Red The ALARM LED lights up if some alarm is active
393.3.1 TITLE BAROn the top of the display, the title bar is shown. It is always visible during browsing the various menus andscreens. In the bar two pieces of information are present.•The name of the screen is displayed on the left (DIAGRAM in the case of the first screen). During settingschange, a confirmation question could appear in this part of the titlebar (see later).•The actual time is on the right side of the bar. The colon symbol between hours and minutes blinks everysecond in order to indicate the progress of time.3.3.2 STATUS BAROn the bottom of the display, the status bar is shown. It is always visible while browsing the various menus andscreens. In the bar five pieces of information are present, as described in the following list (the order is fromthe left to the right of the bar).•The bell icon ( ) on the left gives the user some information about alarm conditions that are present orthat occurred in the past. The icon can be absent, present or blinking. The meanings of these conditionsare detailed in the following table.ICON DESCRIPTIONAbsent No alarms are present and no alarms occurred since the last visit to the logPresent At least an alarm is present at the momentBlinking An alarm occurred since the last visit to the log, but no alarm is present at this moment3.3 MENU MANAGEMENTAfter the initialization screen, the DIAGRAM screen is shown on the display. It represents a simple diagramof the machine: ASI/SMPTE inputs, the ATSC modulator, the up-converter and the amplifier. The mostimportant parameters are also shown in this screen. Pressing the knob while in this menu you will be directedto the RF Power menu for a quick intervention during emergency situations.
40•The lock icon ( ) at the right of the bell icon is displayed when the control is password-locked (see laterin this manual for more information about password locking). When the user unlocks it by typing thecorrect password, the lock icon disappears.•The Forward Power is shown about at the centre of the status bar. It is indicated in Watt. This is thepower as it is measured by the directional coupler at the very last stage of the power amplifier, just beforethe output connector. When the RF is muted, the word MUTE is shown instead of the output power.•The Reflected Power is shown next to the Forward Power. It is indicated in Watt. This is the power as itis measured by the directional coupler at the very last stage of the power amplifier, just before the outputconnector. When the RF is muted, the word MUTE is shown instead of the Reflected Power.•The Temperature is shown at the rightmost side of the status bar. It is indicated in Centigrade degrees.This temperature is measured by a sensor located near the hottest spot of the cooling heat sink of thepower amplifier stage. When a temperature alarm is present (the temperature is over the threshold), thetemperature indication in the status bar blinks.3.3.3 DIAGRAM SCREENThe DIAGRAM screen represents a general schematic view of the ATSC TRANSMITTER. The most importantworking settings are written using a small-size font. By looking at this diagram, the user can have a generaloverview of the equipment status.On the left there is the input section, showing ASI1/ASI2 or SMPTE1/SMPTE2 depending on the selectionmade in INPUT J CONFIGURATION menu. In ASI mode, the upper ASI1 text appears when a valid ASI1input stream is present. The lower ASI2 text appear when a valid ASI2 input stream is present. These wordsblink if a bad input stream is detected. The behaviour is identical in SMPTE mode with a difference only in thestrings: SMPTE1 and SMPTE2 instead of ASI1 and ASI2.The presence of the string indicates only the presence of a corresponding input stream. The actual inputstream used by the modulator is shown by a horizontal line starting from the input name and entering themodulator.Next to the input section, the modulator block is drawn. On top of the rectangle, the ATSC mode is written:8-VSB. The word MODUL blinks if any error associated to the modulator is present.At the bottom of the modulator rectangle, there is the external reference block. If a valid reference is detected,the REF rectangle is drawn. If the external reference is actually used by the modulator, a vertical line connectthe REF to the MODUL rectangles. If the user choose to use the external reference, but a good referencecan't be detected, the REF rectangle blinks.Immediately on the right, the up-converter block is drawn. On top of the rectangle, the RF channel number iswritten if the frequency is chosen by standard/channel couple. Nothing appears if the frequency is set manually.The triangle on the right represents the power amplifier and an hypotetical antenna connected to it. From theoutput of the power amplifier, two lines start: they indicates the output power and the reflected power measuresshown in the status bar at the bottom of the display.
41.3.3.4 BROWSING THE MENUS AND PARAMETERSThe user can browse the menus, see the parameters values, change the settings of the machine and make allthe operations simply by using the knob located on the right of the display. The knob can be rotated left orright and be pushed.From the first screen (DIAGRAM screen), it is possible to rotate the knob to the left to enter the MAINMENU screen.In this screen six icons (INPUT, MOD, RF, SETUP, LOG, ALM) are shown, arranged in 2 lines of 3 icons.The selected icon is drawn in reverse colours. By moving from the DIAGRAM screen, the selected icon willbe ALM, as in figure above. It is possible to select the other icons by rotating the knob again to the left. Byrotating the knob to the right, it is possible to select the icons in the opposite order. When the ALM icon isselected, rotate the knob to the right to go back to the DIAGRAM screen again.
42When an icon is selected, click the knob to enter the associated menu. For example, by clicking the knobwhen the RF icon is selected, the menu related to the RF signal is shown.The ATSC TRANSMITTER is a complex piece of equipment and its setting could be a difficult task. Themultitude of parameters are arranged in six tree-like menus, starting from the six top-level menu icons. In thisway, it is simpler and more comfortable to find the desired parameter.3.3.5 COMPOSITION OF A MENUAn example menu (the RF menu) is depicted in the figure below.The title of the menu (RF in this example) is written at the leftmost side of the titlebar. Every menu is composedby several items, but only four of them are shown at the same time on the display. The first item is always“Exit...”. One of the item is selected and is shown in reverse colours. By rotating the knob to the right(bottom), the selected item is changed and the menu is scrolled down to its last item. By rotating the knob tothe left (up), the menu is scrolled up to its first item. The scrollbar drawn on the left of the items gives an ideaabout the selected item position in the menu: the position of the small tab inside the scrollbar changes dependingon the selected item, from the top to the bottom of the outer rectangle representing the bar. There are 3 typesof item in a menu, characterized by a different suffix appended to the item name:• submenus, with leading dots ( );• read/write parameters, with a right arrow ( ) suffix;• read-only parameters, without any suffix.In case of failure, the value of the failed parameter (read/write or read-only) blinks to show the malfunction,until the alarm condition disappears. If the “Modulator no communication” alarm is present, the value ofparameters related to the modulator is indicated as “???”.- SubmenusA submenu item is indicated by the name of the submenu and the leading dots. By clicking on a submenu (e.g.,by clicking the knob when a submenu item is selected), a new child menu is shown, browsing the tree-like
43There are some “special” read/write parameters that represent only an action to make (e.g., Clear Log). Theirvalue is shown with the symbol. By clicking on this kind of parameter, the symbol is drawn in reversecolours. Click again and choose “Yes” to the confirmation question in order to perform the associated action(e.g., clearing the log content). It should be noticed that, if the control is password-locked or the remotecontrol is enabled, a read/write parameter could become a read-only parameter until the control is unlockedby typing the correct password or the remote control is disabled.- Read-only parametersThe row of a read-only parameter is composed by two parts: the leftmost contains the name of the parameter,the rightmost one contains its value. The user can read this value, but not modify it. In fact, if clicking on aread-only parameter, nothing happens.menu from the top to the bottom. As before, this new (sub) menu is composed by several items that can beother submenus or parameters.Even if it has leading dots, the “Exit...” item, the first item of all menus, isn’t a real submenu. By clicking on“Exit...”, it goes back to the parent menu, if any, browsing the tree-menu from the bottom to the top. If themenu is at the top-level, by choosing “Exit...” the menu icons screen is shown.- Read/write parametersThe row of a read/write parameter is composed by two parts: the leftmost one contains the name of the parameterwith arrow suffix, the rightmost one contains its value or an “action symbol”.By clicking on a read/write parameter, the associated value is written in reverse colours, meaning that it is possibleto change it by rotating the knob. Some parameters can be changed continuously in a range (e.g., the output powerlevel); move the knob to the right (left) to increase (decrease) the value. For other parameters, the value can bechosen from a short list (e.g., the input selection); move the knob to the right (left) to scroll down (up) the list. Forsome other complex parameters, like the frequency or the date, the user can change a token at a time (a digit of thefrequency, a field of the date) by rotating the knob, moving to the next token by clicking on the knob.After choosing the desired new value, click the knob to finish the change. Usually, until now, no real change of theparameter took place (there are some exceptions, well described later). It is necessary to accept the new value byrotating the knob to the right in order to choose the answer “Yes” to the confirmation question (“Sure?”) thatappears at the left of the titlebar. By answering “No” to the confirmation question, the new value is discarded and theparameter keep the old value.
443.4 PARAMETERS AND MENUS DESCRIPTIONThis paragraph contains a detailed description of all the menus and parameters. Please be sure to read thissection very carefully before changing any setting of the exciter. Check the menu map for a general overviewof the parameters.The menus and parameters arrangement is subject to change, mostly with the control firmware version.Your arrangement could be slightly different than the one described in this manual.

47MODULATOR (OK, Err, No Comm)If the ATSC Modulator module is correctly working, this read-only parameter showsOK. If the modulator has an internal error or it doesn't communicate with the controlboard, it shows "Err" or "No Comm".Warning! If this parameter isn't OK, a serious malfunction of a core part of theATSC TRANSMITTER is present. Be sure to solve this problem before installing theequipment at the final destination.Bitrate adapt. (OFF, ON)If this parameter is set to ON, the bitrate is adapted. If it is set to OFF, the bitrate is notadapted.See the TS Input Management paragraph for more information.PRBS (OFF, PRBS, Sinus)With this parameter it is possible to activate the PRBS or Single Tone test mode (see theTest Modes paragraph for more information about the available test modes).3.4.2 MODULATION MENU

Others may be available with future firmware releases.When a custom frequency is set instead, User appears as the standard and channel andthe channel offset is reset.Channel (depending on the selected standard)The user can set the output signal frequency by choosing Standard/Channel pair or bysetting a custom frequency. At the time of printing this manual, the available standards areUHF and VHF. Others may be available with future firmware releases. The channels thatcan be chosen depend on the selected standard (for example, if UHF standard is selected,channel can be changed in the 14-69 interval). When a different standard is chosen (forexample, from VHF to UHF), the first channel (in the example, 14) is automatically set.When a custom frequency is set instead, User appears as the standard and channel andthe channel offset is reset.Channel Offset (-9999÷+9999Hz by 1Hz step)If the frequency is set by using Standatd/Channel pair, it is possible to finely adjust thecenter frequency, by setting this parameter. The offset can be negative and positive.Freq (57÷860MHz by 1Hz step)The user can set the output signal frequency by choosing Standard/Channel pair or bysetting a custom frequency. The digits of the frequency can be changed one at a time inthe 0-9 range (only the first digit can be changed in the 1-8 range). Click on the knob tomove to the next digit. If a value lower than 57MHz (greater than 860MHz) is set, thefrequency 57MHz (860MHz) will be used instead.UPC PLL (Locked, Unlocked)This read-only parameter shows the status of the up-converter PLL. It can be Locked orUnlocked.
50- Power SubmenuPower Control (Manual, Auto)This parameter sets the power control mode as either automatic (AGC) or manual. Seethe AGC: Implementation and details paragraph for more information.Warning! For safety operation it is better to set to 0% the power level that is notselected. For example, if the automatic power control mode is selected, it is betterto set the manual power level to 0%. This way, after changing from automatic tomanual, the output power will safely starts from zero level.Pwr Level Man (0÷100%)This parameter sets the operating level of the output power, if manual power controlmode is selected. Rotate the knob to increase/decrease the level in the 0÷100% range.If the user makes a fast left rotation with a single movement, the power automaticallygoes down to 0%. If the user rotates the knob to the right, the autodecrement will beblocked.See the AGC: Implementation and details paragraph for more information.Note that, differently from the usual read/write parameters, when you rotate theknob the change is immediately active. When you reach the desired value indicatedon the display status bar, click on the knob and choose “Yes” to answer theconfirmation question in order to accept the new power level. Choose “No” toignore the new and restore the old level.Pwr Level Auto (0÷100%)This parameter sets the operating level of the output power, if automatic power controlmode is selected. Rotate the knob to increase/decrease the level in the 0÷100% range. Ifthe user makes a fast left rotation with a single movement, the power automaticallygoes down to 0%. If the user rotates the knob to the right, the autodecrement will beblocked. See the AGC: Implementation and details paragraph for more information.Note that, differently from the usual read/write parameters, when you rotate theknob the change is immediately active. When you reach the desired value, click onthe knob and choose “Yes” to answer the confirmation question in order to acceptthe new power level. Choose “No” to ignore the new and restore the old level.Ext AGC (Disabled, Enabled)You can enable/disable the external AGC by changing the value of this parameter. Please,be sure to deeply understand the AGC implementation details, before changing thisparameter value. See the AGC: Implementation and details paragraph for moreinformation.
51Ext AGC Status (—, Idle, Locked, Lowset, Alarm, Max, Min, Pull-up, Pull-down)This read-only parameter shows the current status of the external AGC that can be oneof the following:• —: the external AGC is disabled;• Idle: the external AGC is stopped (e.g., right after switching on, before the output power reaches the nominal level);• Low Set: the external AGC is stopped because external power reading was too low when the output power was set;• Alarm: the external AGC is stopped because an Alarm signal from external power amplifier is detected;• Locked: the external AGC has reached the desired power level;• Max/Min: the external AGC is stopped because the correction is too high;• Pull up/down: the external AGC is moving up or down the driving power level.See the AGC: Implementation and details paragraph for more information.
52VThis is a read-only parameter that shows the voltage of the RF amplifier stage, measuredin Volt. If this value is outside the normal range, an alarm occurs and the value on thedisplay blinks.IThis is a read-only parameter that shows the current absorbed by the RF amplifier stage,measured in Ampere. If this value is outside the normal range, an alarm occurs and thevalue on the display blinks.Lockout (Present, Absent)This read-only parameter shows whether the lockout condition is present or absent. Incase of presence of lockout, the label blinks (see the Alarms and automation paragraphfor more information).Reset LockoutThis is an “action” parameter that allows to reset the lockout condition. If the lockoutisn’t present, nothing happens (see the Alarms and automation paragraph for moreinformation).Fwd maxThis parameter indicates the threshold of the output power. If the output power is higherthan this threshold, an alarm occurs (see the Alarms and automation paragraph formore information).Ref maxThis parameter indicates the threshold of the reflected power. If the reflected power ishigher than this threshold, an alarm occurs (see the Alarms and automation paragraphfor more information).- Amplifier Submenu
53Spectrum (Normal, Inverted)This parameter enables or disables the spectrum inversion.RF Mute (Auto, ON)If you set this parameter to ON, the output is muted. If Auto is set, the output can bemuted depending on some conditions. In this case, the current mute status is shown inparenthesis.Mute on In. Err (ON, OFF)If this parameter is set to ON, the output will be automatically muted whenever an erroron ASI inputs occurs (for example if the inputs are absent). If it is set to OFF, errors onASI inputs don’t affect the output muting.Mute Type (Fast, Slow)This parameter sets the mute type. If Fast is set, the mute will be direct (abrupt muting).If Slow is set, the mute will be progressive.- Output Submenu
54- Precorrection SubmenuLinear Precorrection (ON, OFF)The linear precorrection feature can be enabled/disable by setting this parameter.See the Linear Precorrection paragraph for more information.Non lin (ON, OFF)With this parameter it is possible to change the non-linear precorrection behaviour of themodulator. If it is set to OFF, the non-linear precorrection is disabled. If it is set to Null,the non-linear precorrection is enabled, but a “null curve” is used. Other non-linearprecorrection curves, up to 10, each characterized by a different name, could be storedinside the controller. In this case, the user can select one of them.See the Non Linear Precorrection paragraph for more information.
55ControlClick on this item to enter the Control submenu to configure the remote control and thepassword locking.Log ClearThis is an “action parameter” and it is used to clear the log content. Be sure to read thelatest events before clearing the log. After clearing, it isn’t possible to undelete the events.Factory SettingsDuring the test phase of the machine, most of all parameters and adjustments are well definedand saved in a non-volatile memory. The user can retrieve and load this configuration byclicking on Factory Settings item menu. Note that after loading the factory settings, manyparameters are changed simultaneously at one time.

56Control (Local, Remote)The ATSC TRANSMITTER is fully-controllable locally (by using the display and theknob) or by remote (by using RS232/RS485 serial ports). With this parameter it is possibleto set local control or remote control. When local control is selected, only readingcommands from remote will be answered, while writing commands will be denied. In thiscase, changing of settings is possible only locally. If remote control is selected, it will bepossible to read the status locally (display) and from remote (RS232, RS485), but changingof settings will be possible only by remote. In this case, many parameters will become asread-only type on the display.Serial (RS232, RS485)The remote control can be performed by using a serial port (RS232 or RS485) or aparallel port (TELEMEASURES). While TELEMEASURES port is always enabled,only one of the two serial ports must be enabled at any time, because they are mutuallyexclusive. If you don’t use remote control, don’t care about this parameter.TLM out (Alarm, Squelch)The meaning of the digital output of TLM port (pins 6 and 7) can be changed by the userin two different modes: Alarm (useful to interface a custom remote control system) andSquelch (useful to interface a switchover control system).PasswordIn order to prevent an unauthorized user from changing the settings of the machine, it ispossible to lock the control by inserting a 5-digits password. When the control is unlocked,the word “Unlocked” is written as parameter value. Click on this parameter and set adigit at a time. After changing the last digit and answering “Yes” to the confirmation question,the control is locked and the word “Locked” appears (the lock symbol is visible on thestatus bar too). Now, the user can’t change any setting by using the knob and display.However, they can continue monitoring the status of the equipment by browsing themenus. Most of the parameters become as read-only type. When the control is locked,click on this parameter to insert the same 5-digits password used to lock. If the passwordis correct, the control will be unlocked, otherwise the control remains locked.Contact the Elettronika Customer Service if you forget the password.- Control Submenu

69CONTROL BOARD AND DISPLAY SCH0135AR1DESCRIPTIONThe Controller module, located on the right side of the DIGITAL TRANSMITTER, is the user interface ofthe whole modulator. It gathers the data from all the sections of the modulator, processes them by means of a16bit flash micro-controller by Fujitsu and makes them available to the user both through the local interface,composed by a display and a knob, and the remote interface made up by the serial port (either the RS232 onthe front or the RS485 on the back, as selected) or the interface of the telemeasuring connector.The acquisition and setting of all the concerned parameters is made in two different ways. Analog measuresreach the board from the individual modules as voltages, are conditioned on the board and then converted byan internal A/D converter in the micro.The remaining parameters are gathered through a 2-wire RS485 interface, with the modulator. The displayboard acts as master on this 485 bus. Besides it is provided with an RTC and a non-volatile memory on aninternal I2C bus.- Dip-SwitchThe display board is provided with 4 dip-switches. The dip-switches 3 and 4 are used to program the flashmemory of the flash micro-controller by Fujitsu, in detail:DIP3: On DIP4: Off Boot ProgrammingDIP3: Off DIP4: On Run or Firmware ProgrammingThe "Boot Programming" configuration is only for BIOS programming purposes.Once the BIOS has been programmed, the firmware has to be programmed at least once in order to use theboard. The firmware programming and the normal operation of the board are obtained with the same positionof the dip switches.For more detail on Firmware upgrade please refer to the "Firmware Upgrade" section.TECHNICAL CHARACTERISTICSFlash ROM 256kByteRAM 6kByteEEPROM 64kBitSerial interfaces 2xRS485 or 1xRS485 + 1xRS232Graphic display 128x64pixel blue with white LED backlightEncoder Mechanical with push buttonClock and Calendar Lithium battery backupTelemeasures Output: FWD, REF, Alarm/MuteInput: Remote ON/OFF
