82.1 OPERATING ENVIRONMENTYou can install the apparatus in a standard component rack or on a suitable surface such as a bench or desk.In any case, the area should be as clean and well-ventilated as possible. Always allow for at least 2 cm ofclearance under the unit for ventilation. If you set the apparatus on a flat surface, install spacers on the bottomcover plate. If you install the apparatus in a rack, provide adequate clearance above and below. Do not locatethe apparatus directly above a hot piece of equipment.2.2 PRELIMINARY OPERATIONSCorrect installation of the equipment is important for maximum performance and reliability. Antenna and earthconnections must be installed with the greatest care. The equipment adjustment isn’t need, because the unit iscompletely adjusted by our technical staff. This is the installation procedure:1. connect the power supply cable of the exciter to the auxiliary socket on the rear panel of the amplifier;2. connect the power supply cable of the amplifier to the electric network (230VAC). If there is the IsolatorTransformer, the amplifier is provided with cable and plug;3. connect the exciter / antenna cables respectively to the RF IN and RF OUT on the rear panel of theamplifier.WARNING!!!FOR ELECTRICAL SAFETY REASONS AND IN ORDER TO KEEPTHE APPARATUS SAFE, THE GROUND TERMINAL OF THEAPPARATUS MUST BE CONNECTED TO THE EXISTING GROUND-ING SYSTEM AND NOT BY USING THE SHIELD OF THE OUTPUTCOAXIAL CABLE.231Three-Phase cablingMonophase cabling
9When the apparatus is put within a combined system it is directly connected to the input splitting and outputcombining systems.Before fully powering the apparatus, check that the output connections of the coaxial cable to the antennasystem are working.In order to this it is possible to check the indication of the reflected power at low power levels. Only if theSWR indication on the display is 0, the output power can be slowly increased. At maximum output power,some watts might be shown as reflected power.2.3 TELEMEASURING SOCKET CONNECTIONSDB9 Socket2.4 RS232, RS485 AND AGC SOCKET CONNECTIONSPIN N° SIGNAL TYPE IN / OUT FUNCTION1Analog OutputFWD Power2 Analog Output REF Power3 Digital Output Temperature4 Digital Input Interlock5 GND - -6 - 7 Digital Output Free contact (closed when alarm)8 Digital Input 0V = ON5V = Normal9 Digital Input 0V = OFF5V = NormalPIN 123456789FUNCTIONS -TxDRxD-GND- - - -RS232 - DB9 SocketPIN 123456789FUNCTIONS -Rx-Rx+5VGND-Tx-Tx+-RS485 - DB9 Socket

13Section 3 - OperationContents:3.1 Operation3.2 Display3.3 Menus
143.1 OPERATIONAt startup, after initial image, the display shows the main screen with the RF powers as in Figure 1:The user may turn on and off the amplifier by means of the switch on the front panel. The control board turnson all the power supplies, the exciter (if any), and internal cooling fans. While the amplifier is working, themicro-controller monitors continuously the most important parameters: power supply voltages, absorbedcurrents, high power zone temperature, forward and reflected powers, unbalances (if any). Each measure isassociated to a maximum threshold beyond which the amplifier is immediately put in protection status byturning off one or more power supply, depending on the failed block. In order to prevent a temporary problemto trigger a definitive protection status, the failed block is turned on again, after some seconds, for up to fivetimes. If it goes beyond the protection threshold for more than five times, it is declared as FAILED and it willno longer be turned on. In this case, the amplifier will have to be turned off manually by means of the switch onthe front panel, then turned on again after performing the needed maintenance.On the front panel there are also three LEDs labelled ON, REMOTE and ALARM. Their meanings areexplained in Table 1.Figure 1: Main screenTable 1: Meanings of the three LEDs on the front panel1 Screenshots in this manual are indicative, so they can be different from those on your equipment.LED COLOUR MEANING MEANING WHEN BLINKINGON Green The amplifier is onThe amplifier has been turned onlocally but it has been turned off byremoteREMOTE Yellow Remote control isenabled It never blinksALARM Red An alarm is present It never blinks
153.2 DISPLAYThe control board is provided with a modern pixels graphic display with blue background. Normally it alwaysshows a title bar (on the top line) and a status bar (on the bottom line).The title bar, see Figure 2, shows the name of the amplifier (TV Amplifier) and the current time. If the amplifieris a single unit coupled externally with other units in a high power transmitter, the title bar shows the amplifiernumber (slave address) too.Figure 2: Title barFigure 3: Status BarThe status bar (Figure 3) indicates the forward and reflected powers and the temperature. It also contains twosymbols for the interlock (lock) and the alarm (bell).The bell symbol is continuously displayed in case of alarm. It blinks if there has been an alarm which has endedbut has not yet been seen by the user. It stops blinking once the Log has been checked.The interlock symbol is displayed only when this function is enabled. It may be either a close lock, as in Figure3, when there is no alarm (interlock chain closed) or an open lock in case of alarm (interlock chain open).Since the status bar is always showed on the display, regardless of the screen, the user may monitor at anytime the most important parameters and the presence of alarms while moving between different screens.3.3 MENUSThe user may see or modify locally some configuration parameters using the four buttons on the front panel.All screens areorganized in a hierarchical menus and the user may move between them in a simple and intuitiveway.To see the menu it’s sufficient to press the ESC key (see Figure 4).
16Figure 4: Main menuThe display only shows three items at a time: all the items can be scrolled by the UP and DOWN arrow keys.Any item can be chosen by selecting it and pressing the RET key. Menu entries with an arrow on the right open sub-menus when chosen. Thus there is a hierarchical structure as in Figure 5. To go back from a sub-menu to the previous menu, press the ESC key. If the ESC key is pressed in the main menu, the RF powersscreen is accessed.Figure 5: Hierarchical menu structureAll menu items are described in detail below.
17- RF PowersThis is the main screen showing the RF powers of the amplifier: forward power, reflected power, unbalances,if any. For forward power a level bar is displayed. See an example in Figure 1.- Power SupplyThis screen shows all the signals coming from two power supply. To check the next (previous) power supplypress the UP (DOWN) key. For each power supply, the voltage, the absorbed current and the status (ON orOFF) are shown.Figure 6: Power supply screen- Log/AlarmsThe control board is provided with an external EEPROM and a clock. Any alarm or switching event with thetime at which it occurred is saved in the EEPROM. The Log/Alarms sub-menu allows to manage this log.It is possible to see the events stored in the log by selecting Log/Alarms View Log/Alarms. All eventscan be scrolled by pressing the UP and DOWN keys. For example, the event shown in Figure 7 is the turningon of the amplifier by means of the local switch. For every event/alarm a short description and the date andtime at which it occurred is displayed.Figure 7: Event stored in the log
18In case of alarm, the value of the measure which caused the alarm is saved into the log. In case of alarm stillexisting after five turning-on attempts, the parameter is marked as FAILED. Table 2 is the list of all the eventswhich can be logged.Table 2: Events managed and logged by the control boardThe log may be completely deleted by selecting Log/Alarms Clear Log/Alarms.Amplifier can store in the log details about alarms and generic events. You can change this behaviour selectingLog/Alarms Log/Mode menu item.- Working TimerThe control board has a working timer which is always enabled while the amplifier is working (i. e. there is atleast one power supply working). The menu entry Working Timer View Timer allows to check the hoursfor which the timer has been enabled. Working Timer Timer Reset resets the timer.- ThresholdsThis is a screen showing the alarm threshold of each signals monitored by the control board. The list can bescrolled by means of the UP and DOWN keys.EVENT DESCRIPTIONLocal ON Amplifier turned on by means of the local switchLocal OFF Amplifier turned off by means of the local switchRemote ON Amplifier turned on remotelyRemote OFF Amplifier turned off remotelyInterlock open Interlock chain openInterlock closed Interlock chain closedPower Supply ON Power supply onFwd Pwr xxxxW Alarm for forward powerRef Pwr xxxxW Alarm for reflected powerUnbY xxxxW Unbalancing alarmV1 xx.xV Power supply voltage alarmI1 xx.xA Power supply current alarm
19- RMS/PeakThe control board can monitor both the RMS and peak powers, the first used in digital systems. The menuentry Settings RMS/Peak allows to choose the power to be displayed and monitored. This menu ispresent only in certain amplifiers.- Date/TimeThis screen allows to set the current date and time. The setting is changed by pressing the arrow keys, thenpressing the RET key to move to the following value and eventually save the changes. To go back to theprevious menu and discard any change made, press the ESC key. Figure 8 shows an example of this screen.Figure 8: Date and time setting screen- DisplayThe menu entry Settings Display allows to change some settings of the display, such has back light,contrast and screensaver. The back light and the contrast are set by means of the UP and DOWN arrowkeys. The changes made are saved by pressing the RET key or discarded pressing the ESC key. Figure 9shows an example of this screen.With Settings Display Screensaver you can set an interval time after which display backlight isturned off. When display backlight is off, press any key to switch it on.Figure 9: Display contrast setting screen
20- Frequency (only for some Amplifiers)The forward and reflected RF powers is measured by means of a directional coupler. In order to compensatefor the effect due to the sampling made by the coupler, it is possible to set the frequency by menu entrySettings Frequency. The setting can be changed by pressing the arrow keys. The changes made aresaved by pressing the RET key or discarded pressing the ESC key. Set the video carrier frequency.- Slave AddressThe amplifier may be used either in stand-alone mode or as a slave of a master in a high power multiple unitstransmitter. In the latter case an unique address for each amplifier has to be specified, in order for all of themto communicate with the master on the same RS485 bus. The menu entry Settings Slave Addressallows to choose the stand-alone mode or set a slave address by means of the UP and DOWN arrow keys.The changes made are saved by pressing the RET key or discarded pressing the ESC key. An example of thisscreen is shown in Figure 10.Figure 10:Slave address setting screen- RemoteThe amplifier may be controlled either locally, by means of the keys and display, or remotely. There are threepossibilities for remote control:- using a direct serial connection between amplifier RS232 connector and a PC RS232;- using the remote control device manufactured by Elettronika S.r.l. (RCU), on the RS485;- using a general-purpose control system connected to telemeasures.You can enable / disable remote control choosing menu item Settings Remote. When remote controlis enabled, the yellow REMOTE LED on the front panel is lit.- InterlockOne of the pins of the telemeasure connector, located on the rear panel, is used for the interlock alarm. It is aninput line which turns off the amplifier in case of alarm. The interlock check can be enabled or disabled using
21menu item Settings Interlock. When it is enabled, the status bar shows the lock symbol (see Figure 3),which is close if the interlock chain is closed (no alarm) or open if it is open (alarm).- Firmware ReleaseThe menu entry Settings Firmware Release allows to display the firmware version number and thehardware release of the amplifier.- Serial NumberThe menu entry Settings Serial Number allows to display the serial number of the apparatus.

29200W UHF LDMOS AMPLIFIER MODULE SCH0192AR0DESCRIPTIONThe RF module is an integrated TV linear amplifier designed for UHF band, this module employs push-pullLDMOS technology in order to achieve very good efficiency, high linearity and reliability.LDMOS transistors operate in AB class. It is a wideband amplifier over the full frequency, no adjustment isrequired for the channel change. The board includes RF section amplifier, bias circuit, protection circuit andmatching networks. A silver plated copper plate is brazed with PCB in order to obtain low thermal resistance.Providing a minimum of 200W Pk sync linear power, this module is the perfect amplifier for any broadbandUHF power transmitter.TECHNICAL CHARACTERISTICSOutput power 300W maxInput power 15W maxFrequency 470 - 860MHzGain > 13dBLDMOS Power supply 32V ±2%LDMOS Bias current @+32V Vdc 2ARF Input impedance 50ΩRF Output impedance 50ΩInput / Output return loss > = 15dBDrain efficiency 47% @ 250WStorage temperature range -50° to +150°CDimensions (LxWxH) 165x95x29mm

31- Calibration stepsSTEP 1. Close the input and the output of the module by connecting them to a 50ΩΩΩΩΩ dummy loadand connect the spectrum analyser through a directive sample, in order to look for self-oscillation of themodule, if any (anyway the module has been designed so that it would not self-oscillate even if totally de-coupled, without any input or output load).STEP 2. Check the voltages of the polarisation circuits without assembling the transistors first:connect the 32V power supply to the proper turret by means of a fastening screw, then give power and checkdata:- the stabilised voltage on the zener diodes DZ1 and DZ2 is about 15V compared to the ground;- the stabilised voltage on the zener diodes DZ3 and DZ4 is about 6.8V compared to the ground;- the voltage on the pads to which the gates of the LDMOS transistors will be soldered (R23 and R24resistors side) changes from 0V to a maximum value of about 6V when moving the relevant trimmer (R7-R8).STEP 3. Check the work of the protections.- Set both trimmers so that there is a value of about 4.5V on the pads of the gates;- solder some wire to the pad between the two LEDs, next to the serigraphy of the input hybrid H1;- in order to check the work of the protections aboard, a power of about 4V has to be supplied to the wire,for example by touching with it the reophore of C23 or C24 which is not connected to ground; the two redLEDs will immediately light up and the two RF transistors will be switched off at the same time: the polarisationcurrent (2A) will decrease to 0 and of course the gain curve displayed by the spectrum analyser will decrease;- after this it is important to restore the position of the two trimmers for the minimum voltage! Thendisconnect the 32V power supply.STEP 4. Fastening of the LDMOS transistors: after properly cleaning the plate surface, smear a thinlayer of silicone fat on the lower side of the flange of the MOSFETs, fasten them to the heat sink and solderthe gate first, then the drain. Solder the two 13pF (ATC) chip capacitors and above them the two 1-5pFSolder a wire
32capacitive trimmers, between the two pair of gates, as shown by the mounting plan.STEP 5. Connect serially a c.c. amperometer to the power supply, with scale starting from more than 5A(i.e. 10A).STEP 6. Power the module and check the MOSFET is not absorbing current; this means that the deviceis integral and working correctly.STEP 7. Slowly turn the R7 trimmer until the MOSFET absorbs 1A, always checking that there are noself-oscillation; under this conditions it is possible to check by means of a digital tester that the voltage on thegate is about 5.2-5.4V.STEP 8. Repeat the previous step for the other section of the module, this time turnign R8 and checkingthat the indication of the current on the amperometer increases to 2A total (which includes the current of theother device left on).STEP 9. Check the response curve of the module by means of the network analyser.STEP 10. Check the response curve for low signal with centre 660MHz and span 500MHz, 2dB/div.STEP 11. The curve should be similar to the one enclosed, with a tolerance of ± 0.5dB. To obtain this, acton the four trimmers C41-C41a and C42-C42a with the proper “calibrator”, inorder to flatten the curve asmuch as possible, especially at the edged of the band which represents the minimum values.STEP 12. Finally, check that the current in stand-by does not increase by more than 15÷20%, reaching atworst 2.3÷2.4A when the heat sink is hot and not ventilated.Note: when mounting-removing the PALLET on the heat sink, tightly fasten the screw of each all “N” input and outputconnectors. These are mounted with a single 3mm screw and if it is not properly fastened it may be detached from the PCBby a movement of the connector once it has already been soldered to the path.

38Figure 1: Simplified block diagram of the control and display boardCONTROL BOARD AND DISPLAY SCH0223AR1DESCRIPTIONThe Control Board SCH0223AR1 manages the operational logic of the amplifier: switching on and off,power supply and fans, alarms and protections, remote control, human-machine interface. All of that isperformed by a modern and powerful 16 bit micro-controller, which is the main part of the board.Figure 1 shows the block diagram.
39It can be seen that the micro-controller is the heart of the control system, to which the various peripherals(power supply, serial ports, telemeasure socket, AGC port, RF amplifier module, ROM, clock, display andkeys) are interfaced.- Power SupplyThe board is powered with a continuous +24V voltage applied on the J14 connector. From that the +5Vvoltage, powering the most of the chips (micro-controller, operational amplifiers, display, etc.) is derived bymeans of a switching converter (see IC19). A +12Vdc voltage is obtained from it as well, by means of a linearconversion provided by the integrated circuit IC8. From this, a -12Vdc voltage is obtained by means of theintegrated circuit IC5. The -12V voltage is used to adjust the contrast of the display.- ConnectorsOn the board SCH0223AR1 there are several connectors used as interfaces for the peripherals of the apparatusand the ports for external communication.POWER SUPPLYThe connectors J1, J6, J8 e J12 are used to connect the power supply powering the RF modules. The numberof power supply used changes depending on the amplifier, up to eight power supply. They are connected inthe order shown in Table 1 below. Remaining connectors, if any, are left unconnected.Table 1: Interface connectors for the power supplyThrough this connection, each power supply provides the level of voltage and current acquired by the micro-controller by means of an internal ADC. Besides the connectors allow the control board to turn on or off theindividual power supply (for instance when an alarm occurs).CONNECTOR POWER SUPPLY N°J1 1 - 2J6 3 - 4J8 5 - 6J12 7 - 8
40RF AMPLIFICATIONThe J3 connector interfaces the control board with the RF amplification section. Through this connector themicro-controller acquires the forward and reflected powers, unbalancing (if any), and temperature of thecritic amplification area. It also allows to inhibit the transistors in case of reflected power alarm, by means ofa totally hardware, thus extremely fast protection.Depending on the apparatus, this connector may also allow to enable or disable the cooling fans of the criticarea.RS485The J11 connector (10 pin socket) is directly wired to a DB9 female connector placed on the rear panel of theapparatus. This communication bus allows to connect the amplifier to the control (Amplifier Control) moduleof a high-power transmitter composed by several individual amplifiers. In this case, each amplifier and theAmplifier Control are connected to the same 4-wires RS485 bus and each of them has a unique address(which can be set by means of the keys and the display) for correct communication.In case of single (stand-alone) amplifier, the RS485 connector can be used to interface to the Remote ControlUnit (RCU) made by Elettronika S.r.l. This unit allows to monitor and control the remote transmitter from anysite provided with PSTN or GSM1 phone connection.Table 2 shows the wiring between the J11 connector on the board and the DB9 female connector on the rearpanel, along with the description of the lines.1 For more details about the control system contact the distributor or the manufacturer.PIN N°ON DB9PIN N°ON J11 DESCRIPTION11 Not used23 Rx-35 Rx+47 +5V59 GND62 Not used74 Tx-86 Tx+98 Not usedTable 2: Description of the RS485 connector
41TELEMEASURESThe J9 telemeasure connector (10 pins socket) is directly wired on a DB9 female connector placed on therear panel. There are input and output digital lines (TTL level) and analog output lines on this connector, whichare used to monitor and control the amplifier by means of a general-purpose remote control system.The correspondence between the pins of the J9 connector on the board and the DB9 female connector on therear panel, as well as the meaning of the various lines, is shown in table 3 below (the directions are in respectto the micro-controller on the board).Table 3: Description of the telemeasures connectorThe input stage of the digital pins has an internal pull-up towards the 5V power supply voltage. To use theselines it only takes setting a switch to close to earth. When closed, the relevant control (turning on or off) isenabled and the switch may be open again (impulse controls).The interlock pin may be used as protection so that the amplifier is switched off when the digital input level islow. It is possible to use several serially connected switches to make an interlock chain. Usually all switchesare closed and the interlock level is low, thus the amplifier is on. If even only one of the switches is open, the(*)(*)(*) You can select by means of two jumpers on the board (JP1 and JP2) RMS or peak power. If there are two jumpers on pins 1 and 2 ofJP1 and JP2 connectors, RMS power is selected. Otherwise, if there are two jumpers on pins 2 and 3 of the same connectors, peak poweris selected.PIN N°ON DB9PIN N°ON J9 TYPE DIRECTION DESCRIPTION1 1 Analog Output Forward power2 3 Analog Output Reflected power3 5 Analog Output Temperature4 7 Digital InputInterlock:0V = Interlock Alarm5V = Normal5 9 - - Ground6-7 2-4 Digital Output Free Contact(closed when amplifier is in alarm)8 6 Digital Input Turning-on control(normally high, active when low)9 8 Digital Input Turning-off control(normally high, active when low)
42Figure 2: Usage of the digital input signals of the telemeasures connectorAGC / EXCITERThe connector called J10, as the telemeasures connector and the RS485 bus, is wired to a DB9 femaleconnector placed on the rear panel of the amplifier. This connector allow the implementation of an automaticgain control between an exciter and the amplifier. A voltage signal related to the forward output powersupplied by the amplifier is provided through two pins of the AGC connector. Connecting one of these to therelevant input pin of the exciter, this can pursuit a given voltage level, so that the output power is alwaysconstant. In order to avoid that, in case of an alarm decreasing the forward power, the exciter increases itsoutput level due to the AGC, thus damaging the amplification stages, the connector is provided with twodigital output lines called AGC Alarm. Under alarm conditions, this lines are brought by the micro-controllerat a low level, so that the exciter can stop the AGC.Table 4 shows the connection between the J10 connector on the board and the DB9 connector on the rearpanel, along with the description of each pin (the direction of the pin is referred to the position of the micro-controller on the board).level of the interlock signal becomes high (this line has a pull-up towards the +5V power supply voltage aswell) and the interlock protection activates switching off the amplifier. Note that in case the interlock protectionis not used, the pin 4 of the DB9 telemeasure connector and the earth pin (pin 5) must be short circuited.Otherwise it is possible to disable the monitoring of the interlock chain from menu (see user manual).Figure 2 shows a typical usage for the digital input signals to turn on and off the amplifier and for the interlockalarm.
43Table 4: Description of the AGC connectorRS232The DB9 female connector on the front panel is an external communication RS232 serial port, through whicha PC can be connected directly to the amplifier in order to perform operations such as the remote control (bymeans of an adequate software2) and the update of the microcontroller firmware.The used communication protocol is asynchronous, at a 19200bps speed, 1 start bit, 8 data bits, 1 stop bit,no parity. No hardware flow control is used. The connector is DCE type and the pin used are shown in Table5.PIN N° ON DB9 123456789DESCRIPTION -TxDRxD-GND- - - -MISCELLANEOUSThe J2 (called AUX), J4, J5 and J17 connectors are not used and are there only for future updates. The SW1dip-switches are partially used for the configuration of the correct mode for the micro-controller. The otherswitches are not used. It is important that the position of the dip-switches is left unchanged, because changingit may set a wrong mode for the micro-controller, affecting the work of the whole amplifier.2 For more information about this application contact the distributor of the manufacturer.PIN N°ON DB9PIN N°ON J10 TYPE DIRECTION DESCRIPTION1 1 - - Ground23DigitalOutputAGC Alarm0V = Alarm5V = Normal35DigitalOutputAGC Alarm0V = Alarm5V = Normal47- -Not used59 - -Not used62 - -Not used7 4 - - Nout used8 6 Analog Output Forward power9 8 Analog Output Forward powerTable 5: Description of the RS232 connector
44FIRMWARE UPDATEThe microcontroller is provided with a built-in Flash memory containing the firmware. The firmware can beupdated with a later version without removing the apparatus from the rack and/or replacing the chip.To upgrade it, connect a PC to the RS232 socket on the front panel of the apparatus by means of a cableDB9 male - DB9 female (pin-to-pin).Launch on the PC the EKAFlash application, select the serial port in use on the PC, choose the update file bypressing the “...” key and click on Download button.Eventually, turn off the amplifier from the main switch and then turn it on again. The upgrade of the firmwarebegins on the EKAFlash window. Fifure 3 shows this window while a firmware is being updated.Figure 3: The EKAFlash window while updating a firmware
