102MULT. UHF LOCAL OSCILLATOR MODULE MTG0084AR0DESCRIPTIONThe synthesis system of the local oscillator for the channel conversion is based on a controltechnique which allows to obtain the programming of the standard, the channel (split intothe three bands I, III, IV/V) and the line offset (as multiple of the line frequency of thevideo signal) via software, with no change to be made.The module includes an internal VCTCXO reference which can be locked to a moreprecise 5/10MHz reference (trough the bus) needed if the field offset is used.TECHNICAL CHARACTERISTICSNominal level +13dBm ±1dBFM S/N ccir unweight. > 65dBFM S/N ccir wght. > 60dBAnalog measures VCO control voltageCarrier frequency synthesis A PLLOffset Line offset, step ±1/12 line frequencyO.L. carrier characteristics On/Off selection and fine adjustFrequency reference Internal TCXO externally lockableExternal interface Microprocessor with RS485 protocolFirmware Re-configurable via RS485

104The module contains the following blocks:1. Local oscillator  generated the carrier to be synthesised, it is split into three windows (I-II / III / IV-Vband) to ensure the coverage of all of the TV channels to be implemented for all standards.2. Radio-frequency splitter  splits the signal coming from the local oscillator by means of splitters andamplifiers, with 10dB attenuation and gain respectively, to ensure the complete isolation of the LO fromthe other stages and to minimise the frequency pulling phenomenon.3. PLL stage  synthesises the desired channel by locking the LO to a 20MHz frequency reference bymeans of a PLL which can be configured via uWire and provides the locking and line-offset indication(LED on frontal panel); the choice is made via software.4. Active ring filter  stabilises the system in PLL retro-action and e has to be modified if the operatingband of the module changes (see table attached to the electrical diagram).5. Conditioning stage of the correction voltage  conditions the correction voltage of the PLL ringproviding a conditioned analog voltage for the A/D conversion; the voltage is processed by themicrocontroller of the display board (see MTG0079) to be displayed as VU-METER.6. Mixer  in the UPCONVERTER version of the module, converts to channel the intermediate frequencycoming from the pre-corrector (see MTG0073) using a LEVEL13 mixer (in case the module is only usedas LO, see REPEATER configuration, this stage is not present and the synthesised carrier goes directly tothe output of the module).7. 20MHz reference  the frequency reference to the PLL synthesis of the carrier is generated by aninternal TCXO which fine control of the frequency is internally generated via PWM by the microcontrolleror, alternately, can be locked to a more precise 5/10MHz external reference (see MTG0076).8. Controller  all of the described operations are managed by a microcontroller communicating to the userinterface board (see MTG0079) by RS485 protocol; the local controller stores the status of the moduleand a reprogramming of the firmware (possible via RS485 from the display board) does not alter itscontents.CALIBRATION PROCEDURE- List of instrumentMEASURE INSTRUMENTLock of the carriers and reference- Spectrum analyser- Oscilloscope- Tester

112CONTROLLER MODULE MTG0079AR0SCH0135AR1 DESCRIPTIONThe Controller module, located on the right side of the VEGATV modulator, is the user interface of the whole modulator. Itgathers the data from all the sections of the modulator, processesthem by means of a 16bit flash micro-controller by Fujitsu andmakes them available to the user both through the local interface,composed by a display and a knob, and the remote interfacemade up by the serial port (either the RS232 on the front or theRS485 on the back, as selected) or the interface of thetelemeasuring connector.The acquisition and setting of all the concerned parameters ismade in two different ways. Analog measures reach the boardfrom the individual modules as voltages, are conditioned on the board and then converted by an internal A/Dconverter in the micro.The remaining parameters are gathered through a 2-wire RS485 interface, which runs on the bus. 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.DIP2: On Factory settingDIP2 is set to ON only during the factory setup of the exciter. This allow to store in the memory all of thesettings made as 'factory defaults'.Once the test is completed, and while the modulator is used normally, the DIP2 must be kept OFF.
113- LEDsThe board is provided with three LEDs.- On (green): it is lit when the exciter is switched on by local or remote control. The LED is blinking till thepower reach his nominal value.- Remote (yellow): it is lit when the exciter has been set to accept remote commands. To have it accept localcommands again, the local/remote selection menu can be used.- Alarm (red): shows that an alarm is present.In case of alarm the red LED lights up and the icon of a bell appears in the upper bar of the display. If the alarmdisappears, the red LED is turned off and the bell starts blinking, in order to show that an anomaly occurred.To know the details of the anomaly and when it occurred, the history menu can be used. Once this menu isaccessed, the blinking bell icon disappears.While an alarm is present the exciter switch off the output power. When the alarm disappear, the power isswitched on again. After 5 times the exciter switch off the output power, the exciter goes in LockOut state: thepower remains off till the user reset the LockOut. If the fails are far more that 1 hour than the LockOut counteris automatically cleaned.TECHNICAL CHARACTERISTICSFlash ROM 256kByteRAM 6kByteEEPROM 64kBitSerial interfaces 2xRS485 or 1xRS485 + 1xRS232Graphic display 128x64pixel blue with white LED back lightEncoder Mechanical with push buttonClock and Calendar Lithium battery backupTelemeasures Output: FWD, REF, AlarmInput: Remote OFFFIRMWARE UPGRADEInside the VEGA exciter there are 5 micro-controllers. One of these is the one of the display board (16bitFujitsu with 256K Flash) while 4 are in the audio, video, local oscillator and external reference boardsrespectively (8bit Microchip with 8K Flash).It is possible to upgrade all of the micro-controllers of the exciter, but the procedures differ from the displayone and the remaining four.All upgrades are made by means of the RS232 connector on the front panel of the exciter.All of the firmware inside the exciter are made up by two parts: the BIOS and the firmware proper. Theformer only programs the built-in Flash memory, while all of the operations of the micro are determined by the
114latter.l Upgrade of the BIOS of the display board:While the exciter is off, set the dip-switched of the board on these positions DIP3:ON DIP4:OFF. Run theFujitsu Flash MCU programmer application, select the BIOS file to be used, select download and follow theinstructions given by the application.l Upgrade of the FIRMWARE of the display board:A display board provided with the BIOS is needed.While the exciter is off, set the dip-switched of the board on these positions DIP3:OFF DIP4:ON. Run theVega Flash Application, select the upgrade of the display board and the file to be used, select download andswitch the exciter on. The upgrade will start automatically.l Upgrade of the boards on the BUS:A working display board is needed in order to upgrade the boards on the BUS, because the programming ofthe modules is made trough the display board.Warning: while it is possible to program both the BIOS and the firmware of the display board, it is onlypossible to change the firmware, and not the BIOS, of the boards on the bus. Since the BIOS is in the samemicro as the firmware, this means that it is not possible to program the micro of a board on the bus on a virginmicro, which can be done, instead, on the display.To proceed with the upgrade, while the exciter is on and remote, run the Vega Flash Application, select theboard to be upgraded and the file to be sent, then select download. The upgrade will start automatically.
