2.1 OPERATING ENVIRONMENT
You 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 of clearance under the unit for ventilation. If you set the apparatus on a flat surface, install spacers
on the bottom cover plate. If you install the apparatus in a rack, provide adequate clearance above and
below. Do not locate the apparatus directly above a hot piece of equipment.
2.2 PRELIMINARY OPERATIONS
Correct installation of the equipment is important for maximum performance and reliability. Antenna
and 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 the
amplifier;
2. connect the power supply cable of the amplifier to the electric network (230VAC). If there is the Isolator
Transformer, 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 OUTPUT
COAXIAL CABLE.

When the apparatus is put within a combined system it is directly connected to the input splitting and output
combining systems.
Before fully powering the apparatus, check that the output connections of the coaxial cable to the
antenna system are working.
In order to this it is possible to check the indication of the reflected power at low power levels. Only if
the SWR 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 CONNECTIONS
The following table summarizes the Telemeasuring pin connections.
2.4 RS232 AND RS485 SOCKET CONNECTIONS
The connector DB25 may be configured as RS232 or RS485 socket, depending on the position of the
jumpers on the board. In case it is used as RS232 socket, the jumpers JP3, JP4, JP5 and JP6 have to be
positioned towards the serigraphy “RS232”. If the jumpers JP1 and JP2 are placed in “N” position, the
follwing configuration is obtained:

2.5 SCH0005AR1 CALIBRATION PROCEDURE
WARNING: this procedure is very delicate, so be VERY CAREFUL in order to avoid damaging
the equipment !!!
First of all turn on the equipment with the correct antenna connection, and then perform the following steps:
- Power supply voltages and currents calibration
Measure with a tester the voltage Vdr1 on the power supply of the first driver transistor without loading the
power supply (this can be done by disconnecting the six supply wires from the RF power modules). Verify
that it is 29V. Then take the calibration load (consisting of five 47Ω/20W resistors connected in parallel) and
connect it between the positive power supply terminal (corresponding to Vdr1) and ground. Turn the trimmer
R1 until you read on the display Vdr1 equal to the value measured before with the tester. Then turn the
trimmer 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 the
voltage 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 is

FUNCTIONS TxD RxD RTS CTS 12V GND 12V
PIN 23456720
FUNCTIONS Rx+ RX- TX- TX+ 12V GND 12V

around 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 value
measured 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 with
the tester the voltages V2-V3-V4 and turn the trimmers R7-R9-R11 until you read on the display the correct
values measured.
To calibrate the remaining currents readings, you have to connect the calibration load to the other three power
supplies (not all together, but one at a time!) and then turn the trimmers R39-R45-R51 until you read on the
display I2=I3=I4= 3.4A.
- Temperature calibration
Measure with a tester the voltage of the OUT pin of the integrated temperature sensor mounted on the heat
dissipating 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 = 0.20
If you get a result of 0.20, it means that the temperature is 20°C, so you have to turn the trimmer R102 until
you read TEMP = 20°C.
- Forward power calibration
Disconnect the antenna and connect a wattmeter (with a suitable dummy load!) to the antenna connector. Put
the cover on the amplifier module and then give power to the equipment until you read 1000W on the
wattmeter. Then turn the trimmer R96 until you read FWD = 1000W (approximately).
- Reflected power calibration
To 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 of
forward 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 the
control board!
64
To ensure the best reliability for the board operations it is advisable that you turn the unused trimmers (those
corresponding to the unused readings connectors) counterclockwise until they reach the zero position (you
will hear a click).
2.6 PREVENTIVE MAINTENANCE
To ensure maximum performance and minimum repair trouble, we strongly recommend you to follow the
below 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 panel
controls;
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 are
running freely.
4. for general maintenance and top performance, call an authorized service technician to give the apparatus
and 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.

PROTECTION BOARD SCH0005AR1
DESCRIPTION
(Stand-alone configuration)
The SCH0005AR1 board is a mi-
croprocessor-based board de-
signed to perform all the control
functions inside the amplifier mod-
ule.
Both RF and power supply param-
eters are continuously monitored in
order to guarantee optimal perform-
ance in every working environ-
ment.
The board checks the power sup-
ply voltages and currents, the work-
ing temperature of the power mod-
ules, the forward and the reflected
RF power of the amplifier.
Various alarm conditions can be
detected by the board due to pos-
sible electrical failures during nor-
mal operation of the amplifier mod-
ule.
The board automatically turns off
the amplifier or part of it when ab-
normal parameters are detected and
restores the initial working condi-
tions if all the parameters return to
allowed values. The board is also
equipped with a serial port connector which, in a near future, will allow the remote control operation
through a local PC or a modem connection.

DESCRIPTION
The display board, PN502, is used to display the main operating parameters of the amplifier module.
The two keys on the right of the LCD display are used to scroll the list of parameters which can be
displayed. These parameters are:
1. Temperature (TEMP)
2. Direct Power (FWD PWR)
3. Reflected Power (REF PWR)
4. Max 6 Power supply voltages (V1...V6)
5. Max 6 Power supply currents (I1...I6)
6. Max 4 Unbalancing powers (UNB1...UNB4)
Depending on the apparatus in which the board is, the parameters 4, 5 and 6 may be less than the ones
listed. The first line of the display shows the type of amplifier or the number of the amplifier module,
referring to the whole apparatus, if this is composed by more than one amplifier. It also shows alarm
conditions, if any, inside the amplifier module. If the amplifier module is turned off by a protection
device, the first line displays “AMPLIFIER OFF”.

1kW LDMOS POWER MODULE MTF0050AR0
DESCRIPTION
The 1000W output power PEP ampli-
fier module has been realized by cou-
pling four 250W Video power modules.
A 4-way Wilkinson coupler, completely
balanced by means of power resistors,
has been used in output. This way an
excellent 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 the
IV/V UHF band and the presence of
parasitic capabilities towards ground,
along with the resistors, required an ac-
curate design of the couple which has
been possible thanks to the use of so-
phisticated simulation software. The
module 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-T
applications. The module is completed by two directional couplers for the reading of Forward and
Reflected power. Besides the by-pass capacitors by TUSONIX used on power supply allow an excel-
lent de-coupling with RF stages.

TESTING AND CALIBRATION INSTRUCTIONS
The 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 the
world standards (intercarrier 4.5 - 6.5MHz). The pass-band section is made up by the group of the four
resonators, while the two separate resonator are the notches. The filter is symmetrical, thus there is no
difference between the upper and lower notch.
The band width is adjusted by changing the insertion of the lower Post Screws which are placed
between the band-pass resonators; inserting the post screws it is increased. In order to perform this
adjustment, loose the bolt of each post screws by means of a wrench n° 19. The first and third post
screws have to be adjusted for the same protrusion from the body of the filter, while the middle one
should 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 adjusted
by means of the two lower Coupling Stubs next to the connectors. The adjustment is made by means of a
flat wrench n° 18, taking into consideration that when the maximum coupling is obtained when the
command 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 by
loosening the relevant lower clamps by means of a tube wrench n° 16. The clamps, once tightened, also
determine 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.

• Set the coupling stubs and the post screws according to the indicative protrusion from their edge to the body
of the filter listed in the table.
• Tune the band-pass section on the wanted channel and load input and output correctly to obtain an
optimal 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). The
input and output couplings may affect the tuning of the resonators, as such they have to be adjusted in
small 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 and
P.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 case
it has moved and then the band-pass tuning. If needed, adjust the middle Post Screws to obtain the best
equiripple 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 following
criterion: 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.
