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, wide­band 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 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.

2.5 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 environ­mental 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.

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).

65

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 sub­menu 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.

66

- 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 the power supply. To check the next (previous) power supply
press the UP (DOWN) key. For each power supply, the two voltages, the two absorbed currents 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

67

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.

- 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

69

- 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

70

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.

- Calibration steps

STEP 1. Close the input and the output of the module by connecting them to a 50

WW

WW

W dummy load

and connect the spectrum analyser through a directive sample, in order to look for self-oscillation of the
module, if any (anyway the module has been designed so that it would not self-oscillate even if totally de­coupled, 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 check
data:

- 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 R24
resistors 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 red
LEDs will immediately light up and the two RF transistors will be switched off at the same time: the polarisation
current (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! Then
disconnect the 32V power supply.

STEP 4. Fastening of the LDMOS transistors: after properly cleaning the plate surface, smear a thin
layer of silicone fat on the lower side of the flange of the MOSFETs, fasten them to the heat sink and solder
the gate first, then the drain. Solder the two 13pF (ATC) chip capacitors and above them the two 1-5pF

Solder a wire

81

capacitive 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 device
is integral and working correctly.

STEP 7. Slowly turn the R7 trimmer until the MOSFET absorbs 1A, always checking that there are no
self-oscillation; under this conditions it is possible to check by means of a digital tester that the voltage on the
gate is about 5.2-5.4V.

STEP 8. Repeat the previous step for the other section of the module, this time turnign R8 and checking
that the indication of the current on the amperometer increases to 2A total (which includes the current of the
other 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, act
on the four trimmers C41-C41a and C42-C42a with the proper calibrator, inorder to flatten the curve as
much 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 at
worst 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 output
connectors. These are mounted with a single 3mm screw and if it is not properly fastened it may be detached from the PCB
by a movement of the connector once it has already been soldered to the path.
