INTRODUCTION
The AUTV/3500LD belongs to the High Power UHF products family of Television Transmitters fully in solid
state technology.
The AUTV/3500LD series represents the 3,5kW TV Transmitters operating in the IV/V Band for Common
amplification process (separate amplification available) of the Vision and Sound carriers. This Transmitters
family has been designed to offer to the customer high performances, high reliability and greater simplicity in
their operation and maintenance procedures.
The Vision and Sound signal processing is provided for all TV Standards and all types of Audio applications
(Mono & Dual sound - NICAM) together with colour systems such as PAL - NTSC - SECAM. Thanks to
the amplitude and phase pre-correction circuit, it is possible to cancel the distortions in the output stage, thus
cutting down the operating costs. The RF transposition in the driver is carried out by a synthesizer with various
possibilities of accuracy and stability as well as precision offset locked by internal or external frequency
reference.
The RF amplifier is made up by three RF modules installed in a power rack, the modules are dedicated for the
Vision and Sound carriers common amplification. The amplifiers employ solid state LDMOS technology in
order to obtain wide band, reliability, and high efficiency. Each RF module has a built-in switching-mode
power supply unit, self-protected against overcurrents and overvoltages, as well as overtemperature and
VSWR for RF parameters. The cooling system is fully contained into the transmitter. The control unit provides
full management of the transmitter without the presence of the operator, the system includes a central controller
and several peripheral units installed in each RF module and rack. The control device includes a fault finding
system to detect equipment malfunctions and locate the faulty subassembly which needs to be replaced. The
interlock circuit is independent on the software and remains always operational whether computer control is
present or not. The operator interface is made by a high resolution LCD graphic display and a simple keyboard,
the menu is very friendly and easy to use.
The Control Unit can be fully controlled in REMOTE mode via link or via modem in RS232 or other interface.
The equipment design allows the soft degradation (RF power loss) for several transistors faults.

1.1 CONTROL SYSTEM OVERVIEW
The control system is made up by some Slave boards, which check locally the amplifier modules, and a
Master board to monitor the status of the Slave boards in each module and show on a graphic display all
the checked parameters.
The number of the Slaves changes depending on the output power of the amplifier. The communication
between Master and Slaves is made via RS485 standard. The Master board reads the overall parameters of
the equipment (Forward and Reflected power and Unbalancing), polls (interrogaes in sequence) the local
boards, shows on the display the values requested by the user, indicates alarm conditions, if any, and allows
to change some of the operating parameters of the apparatus. Besides it realizes a serial data interface to an
external system able to analyse the working parameters of the equipment, using the RS232 and RS485
communication protocols.
1.2 FUNCTIONS
At start-up, the display of Amplifier Control module shows an informational message concerning the equipment
and its firmware version.
- Main menu
The main menu has: a list of the amplifier modules, the measure of some parameters of the power in antenna,
a window with icons to show the alarm status (Alarm Status Window) and some general information, that is
date, time, temperature inside the module and, for FM equipment, transmission frequency.
The following picture is an exact representation of the main menu screen.

if the amplifier module is ON
In the Amplifier List, next to each module, the following symbols can be found:
The UP and DOWN arrow keys allow to select one of the slave, the alarm list, or a menu allowing to change
some settings of the control module and the apparatus; the RET key is used to confirm the selection.
In the main and slave menu the Alarm Status Window (which position is indicated by an arrow in the picture
below) is shown: the gate symbol displays the status of the INTERLOCK, in case of alarm this icon blinks
and the buzzer ringgs.
The INTERLOCK signal is a control available to the user to manage an ON/OFF sensor.
When the relevant PIN is grounded, the Master board does not signal any alarm, as soon as the PIN is left
floating, an alarm is detected; the rotating screw symbol shows that the FANS work normally; in case of alarm
this icon blinks and the buzzer rings; the bell symbol appears in case of alarm detected by the control module
or the amplifier. It blinks if the alarm condition is terminated and the alarm itself can be displayed in the Alarm
List.
If one of the parameters of a Slave or any of the ones directly checked by the Master is alarmed, the general
18
Note that no numerical value is shown for amplifiers which are not communicating with the control module.
alarm LED and the alarm icon blink until the Alarm List is checked to see the type of alarm occurred.
Besides, if an alarm for any of the powers of the signals in antenna occurs, the relevant measure in the
Antenna window of the display and the relevant LED on the front panel of the Master module blink until the
measure decreases below the threshold level, determined by the nominal power of the amplifier.
If the slave modules are working and an INTERLOCK or FANS alarm occurs, aside from the indication
explained above, the amplifiers are switched off. This happens immediately after an INTERLOCK alarm, or
about 7 seconds after a FANS alarm is detected.
In case the amplifiers are communicating but switched off, or they are not communicating and the INTERLOCK
alarm contact is open, a WARNING condition occurs: buzzer on and blinking ALARM LED on the front
panel; while if it is the FANS alarm contact to be open, the icon of the alarm appears in the box.
Further to any of these two alarms it is possible to choose whether to turn off the amplifiers or not. In fact,
there is a submenu of the Settings menu which allows to choose whether to turn off the amplifiers connected
to the control module as a consequence of an INTERLOCK and FAN alarm.
- Slave menu
By selecting one of the slaves, it is possible to see all the parameters of that amplifier module in two pages. The
first one shows voltages and currents Power Supply, the second one shows RF Powers: forward and reflected
power, temperature and, for some amplifiers, unbalancing and input power. The UP and DOWN keys allow
to scroll the local measures of all the slaves, page by page. The ESC key is used to go back to the main menu.
The following pictures show the menu screen of one amplifier.
19
- Alarm List
By selecting the Alarm List, 26 pages listing the latest 130 alarms saved are shown. Each page shows 5
alarms, each contained in a box providing the following information: progressive number of the alarm, starting
with the most recent; number of the module in which the alarm occurred, following the Blk. Message (the
indication AC means that the alarm occurred in the Amplifier Control module); parameter in alarm, date and
time of the alarm. Next to the parameter showing the alarm type there may be a bell symbol. In case it is not
here, the alarm event has been communicated by an amplifier connected to the control module. These events
are different and on option of the Settings menu allows to choose whether they are displayed or not in the
alarm list.
The saved alarm can be deleted by keeping simultaneously pressed the UP and DOWN keys. The ESC key
is used to go back to the main menu. The picture shows a page of the list, containing both alarms and general
events.
1.3 PROGRAMMING MODE
The Settings menu gives access to programming mode. As shown below, the menu offers a list of settings next
to a window showing the default parameter set, or the one selected previously, when the pointer is moved on
the relevant options.
The menu under the cursor is accessed by pressing the RET key. This is shown by the Enabled Menu. Once

SUBMENU OPERATION
Update the time and date shown in the main menu box.
Selection of the analogue voltage signal (PEAK or RMS) to convert and
display the Forward power in antenna. A message in the main menu screen
confirms current choice.
It is possible to remotely control the apparatus, thus to monitor the parameters
shown on the display of Amplifier Control module and check the status of the
transmitter.
This is done through RS232 or RS485 standard serial communication, digital
and analog inputs through the DB25 telemetering connector on the rear panel
of the Amplifier Control module.
If the Local mode is set in this menu, the control module and the apparatus
can only be controlled locally, and a remote command is ignored. If Remote
is set instead, the REMOTE LED on the front panel of the module lights up
after going back to the main screen. From then on, incoming remote commands
from either the serial port or the telemeasuring connector on the rear panel
are handled (Note 1).

1.3 POWER CALIBRATION
- FWD Power calibration
Disconnect the antenna and connect a wattmeter to the antenna connector. Give power to the amplifier until
you will read on the wattmeter a value corresponding to the equipment nominal power. Then turn the trimmer
A (see mounting plan BOTTOM - PN1071AR2, it is a variable resistor used to adjust the A analog input
measure) until you read approximately the same FWD power value on the display.
- REF Power calibration
Disconnect the antenna and connect a wattmeter to the antenna connector. Connect the Forward power
monitoring cable to the Reflected power input connector. Give power to the amplifier until you will read on the
wattmeter a value corresponding to 10% of the equipment nominal power. Then turn the trimmer B (see
mounting plan BOTTOM - PN1071AR2, it is a variable resistor used to adjust the B analog input measure)
until you read approximately the same REF power value on the display.
- UNB Calibration
Connect a wattmeter before the dummy load. Give power to the amplifier then turn off one slave module: you
will read an amount of unbalancing power on the wattmeter. Turn the trimmer C (see mounting plan BOTTOM
- PN1071AR2, it is a variable resistor used to adjust the C analog input measure) until you read approximately
the same UNB power value on the display.

1.1 DESCRIPTION
The AUTV/1500LD is an amplifier operating into Band IV-V for common amplification process of the Vision
and Sound carriers.
The amplifier has been designed to offer to the customer high performances, high reliability and greater
simplicity in his operation and maintenance procedures.
The amplifiers modules employ all solid state LDMOS technology in order to obtain high gain, wide-
band performances, very good linearity, reliability and high efficiency.
The equipment design allows the soft degradation (RF power loss) for several transistor faulty: in fact the
output combiner uses RF power resistors for unbalancing power dissipation. The unit is enclosed in a cabinet
for 19- 6U rackmounting.

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 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 Isolator
Transformer, 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 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 EXISTING GROUND-
ING 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.

2.5 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.

3.1 OPERATION
At 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 turns
on all the power supplies, the exciter (if any), and internal cooling fans. While the amplifier is working, the
micro-controller monitors continuously the most important parameters: power supply voltages, absorbed
currents, high power zone temperature, forward and reflected powers, unbalances (if any). Each measure is
associated to a maximum threshold beyond which the amplifier is immediately put in protection status by
turning off one or more power supply, depending on the failed block. In order to prevent a temporary problem
to trigger a definitive protection status, the failed block is turned on again, after some seconds, for up to five
times. If it goes beyond the protection threshold for more than five times, it is declared as FAILED and it will
no longer be turned on. In this case, the amplifier will have to be turned off manually by means of the switch on
the 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 are
explained in Table 1.
Figure 1: Main screen
Table 1: Meanings of the three LEDs on the front panel
1 Screenshots in this manual are indicative, so they can be different from those on your equipment.
LED COLOUR MEANING MEANING WHEN BLINKING
ON Green The amplifier is on
The amplifier has been turned on
locally but it has been turned off by
remote
REMOTE Yellow Remote control is
enabled It never bli nks
ALARM Red An alarm is present It never blinks
65
3.2 DISPLAY
The control board is provided with a modern pixels graphic display with blue background. Normally it always
shows 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 amplifier
is a single unit coupled externally with other units in a high power transmitter, the title bar shows the amplifier
number (slave address) too.
Figure 2: Title bar
Figure 3: Status Bar
The status bar (Figure 3) indicates the forward and reflected powers and the temperature. It also contains two
symbols 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 ended
but 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 Figure
3, 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 any
time the most important parameters and the presence of alarms while moving between different screens.
3.3 MENUS
The 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 intuitive
way.
To see the menu its sufficient to press the ESC key (see Figure 4).
66
Figure 4: Main menu
The 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 powers
screen is accessed.
Figure 5: Hierarchical menu structure
All menu items are described in detail below.
67
- RF Powers
This 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 Supply
This screen shows all the signals coming from two power supply. To check the next (previous) power supply
press the UP (DOWN) key. For each power supply, the voltage, the absorbed current and the status (ON or
OFF) are shown.
Figure 6: Power supply screen
- Log/Alarms
The control board is provided with an external EEPROM and a clock. Any alarm or switching event with the
time 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 events
can be scrolled by pressing the UP and DOWN keys. For example, the event shown in Figure 7 is the turning
on of the amplifier by means of the local switch. For every event/alarm a short description and the date and
time at which it occurred is displayed.
Figure 7: Event stored in the log
68
In case of alarm, the value of the measure which caused the alarm is saved into the log. In case of alarm still
existing after five turning-on attempts, the parameter is marked as FAILED. Table 2 is the list of all the events
which can be logged.
Table 2: Events managed and logged by the control board
The 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 selecting
Log/Alarms Log/Mode menu item.
- Working Timer
The control board has a working timer which is always enabled while the amplifier is working (i. e. there is at
least one power supply working). The menu entry Working Timer View Timer allows to check the hours
for which the timer has been enabled. Working Timer Timer Reset resets the timer.
- Thresholds
This is a screen showing the alarm threshold of each signals monitored by the control board. The list can be
scrolled by means of the UP and DOWN keys.

69
- RMS/Peak
The control board can monitor both the RMS and peak powers, the first used in digital systems. The menu
entry Settings RMS/Peak allows to choose the power to be displayed and monitored. This menu is
present only in certain amplifiers.
- Date/Time
This screen allows to set the current date and time. The setting is changed by pressing the arrow keys, then
pressing the RET key to move to the following value and eventually save the changes. To go back to the
previous 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
- Display
The 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 arrow
keys. The changes made are saved by pressing the RET key or discarded pressing the ESC key. Figure 9
shows an example of this screen.
With Settings Display Screensaver you can set an interval time after which display backlight is
turned off. When display backlight is off, press any key to switch it on.
Figure 9: Display contrast setting screen
70
- Frequency (only for some Amplifiers)
The forward and reflected RF powers is measured by means of a directional coupler. In order to compensate
for the effect due to the sampling made by the coupler, it is possible to set the frequency by menu entry
Settings Frequency. The setting can be changed by pressing the arrow keys. The changes made are
saved by pressing the RET key or discarded pressing the ESC key. Set the video carrier frequency.
- Slave Address
The amplifier may be used either in stand-alone mode or as a slave of a master in a high power multiple units
transmitter. In the latter case an unique address for each amplifier has to be specified, in order for all of them
to communicate with the master on the same RS485 bus. The menu entry Settings Slave Address
allows 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 this
screen is shown in Figure 10.
Figure 10:Slave address setting screen
- Remote
The amplifier may be controlled either locally, by means of the keys and display, or remotely. There are three
possibilities 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 control
is enabled, the yellow REMOTE LED on the front panel is lit.
- Interlock
One of the pins of the telemeasure connector, located on the rear panel, is used for the interlock alarm. It is an
input line which turns off the amplifier in case of alarm. The interlock check can be enabled or disabled using
71
menu 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 Release
The menu entry Settings Firmware Release allows to display the firmware version number and the
hardware release of the amplifier.
- Serial Number
The menu entry Settings Serial Number allows to display the serial number of the apparatus.
