AUTV/2000LD
LDMOS - UHF TV AMPLIFIER
DESCRIPTION
The AUTV/2000LD is a TV amplifier that can be used in the IV/V Bd UHF. Tutti gli stadi di amplificazione
utilizzano componenti con tecnologia LDMOS, ottenendo eccellenti prestazioni in termini di guadagno e
soprattutto di linearità.
Thanks to the high-quality components used and the strong structure it can be used even in the most hostile
environments with the minimum maintenance.
It is composed by two amplifiers AUTV/1000LD coupled by means of 3dB/90° hybrid couplers ensuring an
high insulation between the apparatuses and a very good input return loss.
The amplifier AUTV/2000LD has been designed using advanced technologies made for broadcasting appli-
cations. All of its components have been tested with thermic shocks in order to obtain a very high reliability
and an high MTBF.
A microprocessor control unit controls the apparatus, checking the thermic, electric and RF parameters,
intervening in case of problems and showing the whole functioning status on a large LCD display.
The purity of the spectrum is ensured by a band-pass filter which removes all the out-of-band spurious
emissions far beyond the level required by the regulations.
The transmitter is provided with linearity pre-corrector to compensate the distortions of the final stage.

1.1 FUNCTIONS
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 I2Cbus standard. The Master
board reads the overall parameters of the equipment (forward and reflected power and unbalancing),
polls (interrogates in sequence) the local boards, shows on the display the values requested by the user
and indicates alarm conditions, if any. 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.
At start-up, the display of the Amplifier Control shows an informational message concerning the equip-
ment and the firmware version.
The main menu has: a list of the amplifier modules, the measure of some parameters of the powers in antenna,
a window with icons to show the alarm status and some general information, that is date, time, temperature
inside the module and, for FM equipment, transmission frequency.
In the Amplifier List, next to each module, you can find the following symbols:

The UP and DOWN arrow keys allow to select one of the slave or the alarm list; the RET key is used to
confirm the selection.
By selecting one of the slaves, it is possible to see all the parameters of that amplifier module, that is voltages
and currents of the power supply, forward and reflected power, temperature and, for some amplifiers,
unbalancing powers. The UP and DOWN keys allow to scroll the local measures of all the slaves. The ESC
key is used to go back to the main menu.
By selecting the Alarm List, two pages listing the latest 20 alarms saved are shown. Each line in these pages
includes the progressive number of the alarm, starting with the most recent, the number of the module in which
the alarm occurred (the indication “AC” means that the alarm occurred in the Amplifier Control module), the
parameter in alarm and the date and time of the alarm. The saved alarm can be deleted by keeping simultane-
ously pressed the UP and DOWN keys. The ESC key is used to go back to the main menu.
In the main menu there is the Alarm Status Window:
displays the status of the INTERLOCK, in case of alarm this icon blinks and the buzzer rings.
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;
shows the status of the FANS: works normally;
in case of alarm this icon blinks and the buzzer rings;
this icon blinks in case of ALARM.
If one of the parameters of a Slave or any of the ones directly checked by the Master is alarmed, the
general 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.
20
In case the amplifiers are communicating but switched off, or they are not communicating and the INTER-
LOCK 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 or not the amplifiers. In fact, if
the DIP-switch n. 2 (see mounting plan BOTTOM - SCH0109BR0) is set to OFF before turning on the
transmitter, the amplifiers will be switched off after a FAN alarm occurs, while it will be kept on if the switch
is set to ON. The DIP-switch n. 3 has the same effect for what concerns the Interlock alarm.
1.2 PROGRAMMING MODE
To access the “Programming Mode”, press simultaneously the ESC and RET keys. The “Setting Time”
menu or the “Setting Frequency” menu can be selected by using the arrow keys, while the RET key confirms
the choice. While this menu is open, no alarm will be signalled until the return to the main menu. If no key is
pressed for about 50 seconds, the main menu is automatically displayed.
The Setting Time menu allows to set the following functions: hour, minute, day, month and year. The selected
parameter blinks and can be modified with the arrow keys; the RET key confirms the changes, while the ESC
key cancels them.
The “Setting Frequency” menu appears only in the FM amplifiers. To visualize the power emitted by the
antenna correctly, set the frequency nearest to the working frequency of the transmitter in the frequency
programming menu. The selected parameter blinks and can be modified with the arrow keys; the RET key
confirms the changes, while the ESC key cancels them.
1.3 SETTING
Set the RS232-RS485 mode on the SCH0109BR0 Control board:
RS232 MODE - DIP-switch n. 1 set to ON before turning on the transmitter: the RS232 mode allows a
direct access to the equipment via PC and a remote access via modem or switched telephone line.
RS485 MODE - DIP-switch n. 1 set to OFF before turning on the transmitter. ThevRS485 mode allows a
remote access to the equipment via modem over switched telephone line or GSM network. It allows the
connection to the Remote Control System, designed to monitor several apparatuses located at the same site.
- 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
21
A (see mounting plan BOTTOM - SCH0109BR0, 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 - SCH0109BR0, 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 - SCH0109BR0, 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.

It is possible to remotely control the apparatus, thus to monitor the parameters shown on the display of the
Amplifier Control and check the status of the transmitter. This is done through RS232 and RS485 standard
serial communication, digital and analog inputs through the DB25 telemetering connector on the rear panel of
the Amplifier Control.
The pins n. 1 and n. 14 of this connector are used to receive the ON (pin n. 1) and OFF (pin n. 14)
commands, both impulsive and stationary. The digital level on these contacts is usually high, becoming low
when the remote control is active. When a remote command to turn off the amplifiers is received while the
transmitters is ON, the LED ON of the frontal panel blinks and the REMOTE LED lights up.

1.1 DESCRIPTION
The AUTV/1000LD 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 amplifier is put in a 20U rack just ready for a double driver use. Inside the rack there is also the output
band-pass filter.
