ABE Elettronica is proud to present the MTX"" Compact Series of Transmitters - Transposers - Gapfillers for Analog and Digital Terrestrial Television

Broadcasting (DVB-T/H, DVB-T2, ISDB-T/Tb, ATSC and other standards).

With the company's 30 years of experience in this field, the ""MTX"" Series is the ultimate in technology, quality and performance it is designed to take advantage of the excellence of the digital modulation systems to generate both Analog and Digital emissions.
This new ""MTX"" Compact Series of Transmitters -Transposers - Gap-fillers brings together the highly efficient and reliable ABE MOS and LD-MOS broadband
Power Amplifiers with state-of-the-art technological solutions.

he Compact MTX Transmitter/Transposer Series is a professional
product line, suitable for the integration in both analog and digital
TV transmission networks (DVB-T/H, DVB-T2, ISDB-T/Tb and
others operating both MFN and SFN).
The equipment is fully contained in a single 19"" rack drawer and is
capable, with its internal RF power amplifier, to provide up to
500Wavg digital output or 1,000Wp.s. in analog mode.
Featuring a modular construction - with easily replaceable boards
and parts - the MTX exploits the advantages of latest components
and mounting technologies to achieve high-reliability and comprehensive
system flexibility - all in a reduced footprint.
Maintenance, control as well as parameter changes and settings,
are simple and easy-to-perform operations.
The equipment can be equipped with one or more digital processor
boards according to the calculation and processing capacity requested
by the TV standard/s implemented in the transmitter /
transposer.
For example, if the unit is used for analog multistandard TV emission
(B,G,D,H,I,K,K1,M,N standard) or for one of the first generation
digital TV standards (e.g.: DVB-T/H, ISDB-T.) just one digital
processor board is enough.
The digital processor board can store one or more different TV
standards without any firmware upgrade.
If optional functions are needed (like re-multiplexing, seamless
switching and others) it is necessary to equip the unit with two
digital processor boards. For the DVB-T2 TV standard are necessary
three digital processor boards.

Additional features of the ""MTX"" Series transmitters also include:
 Comprehensive monitoring and protection circuits, including a
Power Amplifier fold-back function to reduce output power before
tripping off, due to high VSWR, heat-sink over-temperature or overdrive
 Soft Start function to avoid output power surges
 ALC (Automatic Level Control) to stabilize the Power Amplifier's RF
output level over a limited range.
The innovative management and control board of the equipment is
built around a 32 bit micro-controller with the following key characteristics:
 Local Control from the front panel, easy and friendly, with LCD
graphic display LCD and keypad
 LAN Interface (Ethernet Base T 10/100 - RJ45 connector) in addition
to RS485

 Web Server with access protected by username/password (3
different levels of control) able to read/set all the equipment parameters
 Event Logger (recording with date & time of all events of
alarms, power-on, fault conditions etc.) with storage of more than
5,000 events and is downloadable through the transmitter's WEB
Server
 Remote Upgrade Function for the control board firmware
 Email Client for the automated notification, via email to preprogrammed
addresses, of changes in alarm conditions
 SNMP Agent able to send alarms (""traps""), to read equipment
parameters (through the ""get"" command), to set the equipment
(i.e. reset through the ""set"" command)
The connection between the transmitter's LAN interface and the
control centre can be established by means of a GPRS or UMTS
modem / router, a radio data -link or an ADSL or PSTN modem.
