602.1 OPERATING ENVIRONMENTYou can install the apparatus in a standard component rack or on a suitable surface such as a bench ordesk. In any case, the area should be as clean and well-ventilated as possible. Always allow for at least2 cm of clearance under the unit for ventilation. If you set the apparatus on a flat surface, install spacerson the bottom cover plate. If you install the apparatus in a rack, provide adequate clearance above andbelow. Do not locate the apparatus directly above a hot piece of equipment.2.2 PRELIMINARY OPERATIONSCorrect installation of the equipment is important for maximum performance and reliability. Antennaand earth connections must be installed with the greatest care. The equipment adjustment isn’t need,because the unit is completely adjusted by our technical staff. This is the installation procedure:1. connect the power supply cable of the transmitter to the auxiliary socket on the rear panel of theamplifier;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 cable to the RF IN and RF OUT on the rear panel of the amplifier.WARNING!!!FOR ELECTRICAL SAFETY REASONS AND IN ORDER TO KEEP THE APPARATUS SAFE,THE GROUND TERMINAL OF THE APPARATUS MUST BE CONNECTED TO THE EX-ISTING GROUNDING SYSTEM AND NOT BY USING THE SHIELD OF THE OUTPUTCOAXIAL CABLE.1233
61When 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 theantenna system are working.In order to this it is possible to check the indication of the reflected power at low power levels. Only ifthe SWR indication on the display is 0, the output power can be slowly increased. At maximum outputpower, some watts might be shown as reflected power.2.3 TELEMEASURING SOCKET CONNECTIONSThe following table summarizes the Telemeasuring pin connections.2.4 RS232 AND RS485 SOCKET CONNECTIONSThe connector DB25 may be configured as RS232 or RS485 socket, depending on the position of thejumpers on the board. In case it is used as RS232 socket, the jumpers JP3, JP4, JP5 and JP6 have to bepositioned towards the serigraphy “RS232”. If the jumpers JP1 and JP2 are placed in “N” position, thefollwing configuration is obtained:DB9 SocketPIN 23567820FUNCTIONS RxD TxD RTS 12V GND 12V 12VN° Pin SYGNAL TYPE IN/OUT FUNCTION1 Ground2 Logical Input 5V= On - 0V= Off3 Analog Output Dir Power4 Analog Output Ref Power5 Analog Output Unbalancing6 Analog Output Temperature7 Analog Output Alarm 5V= On - 0V= Off8N.C.9N.C.
62If the jumpers JP1 and JP2 are put in “M” position, the following configuration will be obtained:In order to use the connector as RS485 socket, the jumper JP3, JP4, JP5 and JP6 have to be positionedtowards the serigraphy “RS485”. In this way, the following configuration will be obtained:2.5 SCH0005AR1 CALIBRATION PROCEDUREWARNING: this procedure is very delicate, so be VERY CAREFUL in order to avoid damagingthe equipment !!!First of all turn on the equipment with the correct antenna connection, and then perform the following steps:- Power supply voltages and currents calibrationMeasure with a tester the voltage Vdr1 on the power supply of the first driver transistor without loading thepower supply (this can be done by disconnecting the six supply wires from the RF power modules). Verifythat it is 29V. Then take the calibration load (consisting of five 47Ω/20W resistors connected in parallel) andconnect it between the positive power supply terminal (corresponding to Vdr1) and ground. Turn the trimmerR1 until you read on the display Vdr1 equal to the value measured before with the tester. Then turn thetrimmer R22 until you read on the display Idr1 = 3.1A.Repeat the procedure above for the power supply of the second driver stage: measure with the tester thevoltage Vdr2 and turn the trimmer R3 and R27 until you read on the display the correct values.Measure with a tester the voltage V1 on the power supply of the first final power transistor. Verify that it isPIN 23456720FUNCTIONS TxD RxD RTS CTS 12V GND 12VPIN 23456720FUNCTIONS Rx+ RX- TX- TX+ 12V GND 12V
63around 32V. Then take the calibration load and connect it between the positive power supply terminal(corresponding to V1) and ground. Turn the trimmer R5 until you read on the display V1 equal to the valuemeasured before with the tester. Then turn the trimmer R33 until you read on the display Idr1 = 3.4A.Repeat the procedure above for the power supplies of the remaining three power transistors: measure withthe tester the voltages V2-V3-V4 and turn the trimmers R7-R9-R11 until you read on the display the correctvalues measured.To calibrate the remaining currents readings, you have to connect the calibration load to the other three powersupplies (not all together, but one at a time!) and then turn the trimmers R39-R45-R51 until you read on thedisplay I2=I3=I4= 3.4A.- Temperature calibrationMeasure with a tester the voltage of the OUT pin of the integrated temperature sensor mounted on the heatdissipating element. Than perform the operation explained in this example:- voltage measured (for example) = 2.93V- fixed number = 2.73- perform subtraction: 2.93-2.73 = 0.20If you get a result of 0.20, it means that the temperature is 20°C, so you have to turn the trimmer R102 untilyou read TEMP = 20°C.- Forward power calibrationDisconnect the antenna and connect a wattmeter (with a suitable dummy load!) to the antenna connector. Putthe cover on the amplifier module and then give power to the equipment until you read 1000W on thewattmeter. Then turn the trimmer R96 until you read FWD = 1000W (approximately).- Reflected power calibrationTo perform the reflected power calibration just disconnect the REF SMB (J6) and the FWD SMB (J7)connectors from the control board and connect the forward power reading cable to J6 (REF). Give 50W offorward power to the equipment and turn the R97 trimmer until you read on the display REF = 50W.Note: When you have completed this calibration be sure to restore the original connections on thecontrol board!
64To ensure the best reliability for the board operations it is advisable that you turn the unused trimmers (thosecorresponding to the unused readings connectors) counterclockwise until they reach the zero position (youwill hear a click).2.6 PREVENTIVE MAINTENANCETo ensure maximum performance and minimum repair trouble, we strongly recommend you to follow thebelow stated headlines for preventive maintenance:1. check antenna installation and ground connection at regular intervals;2. keep your apparatus clean and dry externally: this will ensure continuous functioning of the front panelcontrols;3. if the apparatus has not been used for a long period of time combined with exposure to extreme environ-mental conditions, open the unit and make a visual inspection.Remove salt, water or ice with a moist cloth before turning the apparatus on. Check that the cooling fans arerunning freely.4. for general maintenance and top performance, call an authorized service technician to give the apparatusand the complete antenna/earth connection installation a general check every 12-18 months;5. check at regular intervals that the air intake located on the front panel is free of dust. If there is visible dust,remove it by means of a soft brush.

901kW LDMOS POWER MODULE MTF0050AR0DESCRIPTIONThe 1000W output power PEP ampli-fier module has been realized by cou-pling four 250W Video power modules.A 4-way Wilkinson coupler, completelybalanced by means of power resistors,has been used in output. This way anexcellent de-coupling between the am-plifier is obtained, as well as the possi-bility to work even with only one ac-tive module. The high extension of theIV/V UHF band and the presence ofparasitic capabilities towards ground,along with the resistors, required an ac-curate design of the couple which hasbeen possible thanks to the use of so-phisticated simulation software. Themodule also has two 40W class A driv-ers realized with LDMOS technology,one for each couple of final modules.All the amplification chain is then real-ized LDMOS technology. The high gain of the output stages allows to drive them with class A drivers,thus giving the module high linearity characteristics, which can be especially appreciated in DVB-Tapplications. The module is completed by two directional couplers for the reading of Forward andReflected power. Besides the by-pass capacitors by TUSONIX used on power supply allow an excel-lent de-coupling with RF stages.TECHNICAL CHARACTERISTICSOutput power 1000W Sync.

103TESTING AND CALIBRATION INSTRUCTIONSThe output filter Mod. CL4NL22 is made up by a 4-resonator band-pass section and two “notch”resonators. It can be adjusted on all the channels of the TV UHF band (470 ÷ 860MHz) and on all theworld standards (intercarrier 4.5 - 6.5MHz). The pass-band section is made up by the group of the fourresonators, while the two separate resonator are the notches. The filter is symmetrical, thus there is nodifference between the upper and lower notch.The band width is adjusted by changing the insertion of the lower Post Screws which are placedbetween the band-pass resonators; inserting the post screws it is increased. In order to perform thisadjustment, loose the bolt of each post screws by means of a wrench n° 19. The first and third postscrews have to be adjusted for the same protrusion from the body of the filter, while the middle oneshould usually be adjusted in a slightly different manner in order to obtain an equiripple response.The input and output coupling, which can be reached by removing the protection cups, can be adjustedby means of the two lower Coupling Stubs next to the connectors. The adjustment is made by means of aflat wrench n° 18, taking into consideration that when the maximum coupling is obtained when thecommand cuts are parallel to the longer side of the filter, the minimum when they are orthogonal to it.The response symmetry is determined by the protrusion of the above mantioned stubs; these are set byloosening the relevant lower clamps by means of a tube wrench n° 16. The clamps, once tightened, alsodetermine the friction of the rotatio of the couplings.The suggested calibration sequence os the following:set the measuring instrument on- C.G. = (P.V. + P.A.) / 2- SPAN = INTERCARRIER * 5 (Es. 27,5MHz std. B/G)- RESPONSE = 5dB/div.- ADAPTATION = 10dB/div.Center Frequency[MHz=] Coupling Stub[mm=] Post Screw[mm=]474 2 6570 16 15666 29 17762 38 17858 40 17
104• Set the coupling stubs and the post screws according to the indicative protrusion from their edge to the bodyof the filter listed in the table.• Tune the band-pass section on the wanted channel and load input and output correctly to obtain anoptimal response. At this stage the tuning of the two notches have to be kept distant from one another.Adjust the band width to -35dB at the limits of the screen (Es. std. B/G: BW (-35dB) = 27,5MHz). Theinput and output couplings may affect the tuning of the resonators, as such they have to be adjusted insmall steps, one after another. The equiripple response is obtained by adjusting the middle Post Screws.• Tune the two notches bringing them to the frequencies P.V.-INTERCARRIER andP.A.+INTERCARRIER. This will cause a change in the response and the adaptation of the band-pass.Correct the response by acting on the band-pass tuning.• Complete the calibration on both sides in this sequence: adjust the coupling, re-tune the notch in caseit has moved and then the band-pass tuning. If needed, adjust the middle Post Screws to obtain the bestequiripple adaptation. Perform this sequence in little steps trying to obtain the best adaptation.• Check the symmetry of the obtained response, and correct it if needed according to the followingcriterion: if the lower notch is more accentuated than the other one, insert the coupling stubs, otherwise,if the upper one is more accentuated, extract them.• Once the symmetry of the response has been corrected, complete the calibration as explained above.Once the calibration has been completed, put again the protection cups on the coupling regulators.Insertion loss @ P.V.
