INTRODUCTIONINTRODUCTION
INTRODUCTION
•The series ETLUW4G03 TV Transmitter provides linear, class “AB” amplification of R.F. TV signal in
the standard UHF bands IV-V (470 to 860MHz).
•ETLUW4G03 is designed to work both in DTV mode and ATV mode.
•Rated R.F. output power is set to 2kW (rms) for DTV mode and 5kW peak sync for ATV mode.
•The use of high efficiency, high power gain LDMO power transistors allows to obtain highly
efficient amplifier modules as ETL0W474G.
•The Amplifier modules of ETLUW4G03 are liquid-cooled. In each ETL0W474G amplifier module a
serpentine cooling duct routed through the heat-sink optimally cools the power transistors and R.F.
units greatly reducing the temperature of active elements. This involves an efficiently use and longer
lifetime of the system.

FUNCTIONAL DESCRIPTION
•The main transmitter components are:
⇒transmitter racks with built in isolation mains transformer and power distribution,
⇒dual drive exciter with changeover or single drive exciter,
⇒power splitters,
⇒R.F. amplifier modules,
⇒power combiners,
⇒output filter.
•The exciter modulates the analog video and audio signals or digital MPEG-2 A I data inputs onto
the set channel frequency, providing pre-correction circuit that ensures linear transmission with the
minimum intermodulation products.
•The power splitter distributes the output power of the exciter to the R.F. amplifier modules.
The R.F. broad band amplifier modules provide linear, class “AB” amplification of composite
Vision+ ound TV signals, and are compatible with digital TV standards DVB-T/H, DVB-T2, I DB-T,
AT C.
•A power combiner combines the output power of the R.F. amplifier modules to the total transmitter
output power.
•An output filter is installed for the suppression of the out of band interferences of the transmitter.

•At the bottom of the cabinet a three phase isolation transformer provides:
⇒lightning protection and isolation from mains
⇒single phase 230V current to supply exciters, supervisor units with change-over logic
⇒three phase 57V current to supply R.F. amplifier modules
•The primary side of the mains transformer is protected by an automatic breaker used to switch on
and off the transmitter.
•The electric current from the secondary side of the transformer is distributed to each R.F. amplifier
module by an individual secondary winding and an individual automatic breaker. o each amplifier
module can be individually switched on and off.
•A secondary winding and an automatic breaker are dedicated to supply electric current to Exciters
and supervisor module of the Transmitter unit.

•With reference to the general blocks diagram shown in Figure 4, the output signal from the Exciter
reaches the input low power divider which splits the drive signal into three components. This system
incorporates a step attenuator and a step phase shifter to balance the slight gain and phase
differences of R.F. Amplifiers. The resultant signals drive the three ETL0W474G R.F. Amplifiers. The
Output power combiner at the output of the three R.F. Amplifier modules combines the output
signals to a nominal level of 2kWrms.

•At the end of the R.F. output line, a directional coupler collects samples of forward & reflected output
power, which are sent to the ETL0700TA Transmitter upervisor & Controller.
•The ETL0700TA controller is used in the transmitter system to monitor and control all amplifier
parameters and to allow the data exchange between the transmitter and an external control via the
serial ports R 232 and R 485.
•The ETL0700TA module executes the following functions:
⇒Monitors the Forward output power
⇒Monitors the Reflected power and generates the “antenna V WR alarm” command
⇒Monitors the output power and all parameters of all the amplifier modules
⇒Controls the enable of amplifier modules, exciters and Hydraulic Unit
⇒Monitors the parameters of the Hydraulic Unit
⇒Establishes data communication of the transmitter with an external control via the R 232
and R 485 serial port
•Through a “CAN BU ” line named serial E-LINK the controller module establishes a bidirectional
communication with the amplifier modules.
hould one of the R.F. amplifier modules enters in alarm status, the controller will send a command
to the other amplifier that will consequently enter into the warning state lowering the supply voltage
by 10%.
•TX Mode: ETL3100 TV Exciter Device configuration (DVB-T/H, DVB-T2, I DB-T, AT C, Analog TV,
Transposer and DVB-T Remodulator) determines analog or digital transmission mode. The exciter
also sends this information to the supervisor by an E-Link bus remote control message. The
supervisor sends the same information to the R.F. amplifier modules.

•Turn on “Amplifier” switches of the Transmitter unit. These switches provide power supply to amplifier
modules of the Transmitter unit. Each amplifier has its own switch so each amplifier module can be
turned off individually.
•Turn on the “On/Off” switch on the front panel of each Exciter.
Now the Transmitter unit is completely switched on. The display of each module should be operating.
•Make sure there are no alarm status for the Transmitter unit.
•Check that exciter modules are set in “Local” mode and in “Off” status.
Now is possible to enable R.F. output power from the Transmitter unit.
•Enable R.F. output power of the Transmitter unit by means of “TX On” command on Transmitter
upervisor & Controller unit.
