MULT. UHF LOCAL OSCILLATOR MODULE MTG0084AR0 DESCRIPTION The synthesis system of the local oscillator for the channel conversion is based on a control technique which allows to obtain the programming of the standard, the channel (split into the three bands I, III, IV/V) and the line offset (as multiple of the line frequency of the video signal) via software, with no change to be made. The module includes an internal VCTCXO reference which can be locked to a more precise 5/10MHz reference (trough the bus) needed if the field offset is used. TECHNICAL CHARACTERISTICS Nominal level FM S/N ccir unweight. FM S/N ccir wght. Analog measures Carrier frequency synthesis Offset O.L. carrier characteristics Frequency reference External interface Firmware 102 +13dBm ±1dB > 65dB > 60dB VCO control voltage A PLL Line offset, step ±1/12 line frequency On/Off selection and fine adjust Internal TCXO externally lockable Microprocessor with RS485 protocol Re-configurable via RS485 103 The module contains the following blocks: 1. Local oscillator generated the carrier to be synthesised, it is split into three windows (I-II / III / IV-V band) 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 and amplifiers, with 10dB attenuation and gain respectively, to ensure the complete isolation of the LO from the 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 by means 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 operating band 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 ring providing a conditioned analog voltage for the A/D conversion; the voltage is processed by the microcontroller 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 frequency coming from the pre-corrector (see MTG0073) using a LEVEL13 mixer (in case the module is only used as LO, see REPEATER configuration, this stage is not present and the synthesised carrier goes directly to the output of the module). 7. 20MHz reference the frequency reference to the PLL synthesis of the carrier is generated by an internal TCXO which fine control of the frequency is internally generated via PWM by the microcontroller or, 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 user interface board (see MTG0079) by RS485 protocol; the local controller stores the status of the module and a reprogramming of the firmware (possible via RS485 from the display board) does not alter its contents.

It gathers the data from all the sections of the modulator, processes them by means of a 16bit 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 on the 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 measures reach the board from the individual modules as voltages, are conditioned on the board and then converted by an internal A/D converter in the micro. The remaining parameters are gathered through a 2-wire RS485 interface, which runs on the bus. The display board acts as master on this 485 bus. Besides it is provided with an RTC and a non-volatile memory on an internal I2C bus. - Dip-Switch The display board is provided with 4 dip-switches. The dip-switches 3 and 4 are used to program the flash memory of the flash micro-controller by Fujitsu, in detail: DIP3: On DIP4: Off DIP3: Off DIP4: On Boot Programming Run or Firmware Programming The "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 the board. The firmware programming and the normal operation of the board are obtained with the same position of the dip switches. For more detail on Firmware upgrade please refer to the "Firmware Upgrade" section. DIP2: On Factory setting DIP2 is set to ON only during the factory setup of the exciter. This allow to store in the memory all of the settings made as 'factory defaults'. Once the test is completed, and while the modulator is used normally, the DIP2 must be kept OFF. 112 - LEDs The 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 the power reach his nominal value. - Remote (yellow): it is lit when the exciter has been set to accept remote commands. To have it accept local commands 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 alarm disappears, 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 is accessed, the blinking bell icon disappears. While an alarm is present the exciter switch off the output power. When the alarm disappear, the power is switched on again. After 5 times the exciter switch off the output power, the exciter goes in LockOut state: the power remains off till the user reset the LockOut. If the fails are far more that 1 hour than the LockOut counter is automatically cleaned. TECHNICAL CHARACTERISTICS Flash ROM RAM EEPROM Serial interfaces Graphic display Encoder Clock and Calendar Telemeasures 256kByte 6kByte 64kBit 2xRS485 or 1xRS485 + 1xRS232 128x64pixel blue with white LED back light Mechanical with push button Lithium battery backup Output: FWD, REF, Alarm Input: Remote OFF FIRMWARE UPGRADE Inside the VEGA exciter there are 5 micro-controllers. One of these is the one of the display board (16bit Fujitsu with 256K Flash) while 4 are in the audio, video, local oscillator and external reference boards respectively (8bit Microchip with 8K Flash). It is possible to upgrade all of the micro-controllers of the exciter, but the procedures differ from the display one 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. The former only programs the built-in Flash memory, while all of the operations of the micro are determined by the 113 latter. 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 the Fujitsu Flash MCU programmer application, select the BIOS file to be used, select download and follow the instructions given by the application. 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 the Vega Flash Application, select the upgrade of the display board and the file to be used, select download and switch 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 of the 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 only possible to change the firmware, and not the BIOS, of the boards on the bus. Since the BIOS is in the same micro as the firmware, this means that it is not possible to program the micro of a board on the bus on a virgin micro, 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 the board to be upgraded and the file to be sent, then select download. The upgrade will start automatically. 114 115 Component layout SCH0135AR1 - Bot layer Component layout SCH0135AR1 - Top layer 116 SCH0231AR1 DESCRIPTION The power supply accepts a nominal continuous input voltage of 28V and supplies three continuous current output with voltages of +5V, +15V and -15V. It also provides a voltage of +28V to the system bus. The power supply voltages towards the system bus are switched by means of relays controlled by the microprocessor of the control board. There are switching regulators for the +5V, +15V and -15V voltages. The power supply board provides the operating voltages to the control board trough multi-wire flat cable. In this there are also analog voltages to monitor the power supply status. The monitoring of the +5V, +15V and -15V voltages are conditioned to about 4V nominal. The board provides the power supply to the system fan. Its on/off status and its speed can be set by the micro-processor of the control board. The connections to the system bus and power supply board are made using a fast-lock connector. Component layout SCH0231AR1 117 EXTERNAL REFEREMENT MODULE MTG0076AR0 DESCRIPTION The board contains the 5/10MHz external reference and a series of functions on the back of the apparatus: the rear audio and video inputs, the telemeasuring connectors and the RS485, the external reference input (or output) and the IF connection before the linearity pre-corrector, in order to allow the insertion in the chain of different modulation systems such as NICAM.
