The new “MTX” Driving Unit brings together the advantages ofsoftware defined radio with state-of-the-art technology solutions.

ABE Elettronica is proud to present the Multistandard Multimode“MTX” Driving Unit for Analog and Digital Terrestrial TelevisionBroadcasting (DVB-T/H, DVB-T2, ISDB-T/Tb and other standards). With the company’s 30 years of experience in this field, the “MTX”Driving Unit is the ultimate in technology, quality and performance. The unit has been designed to take advantage of the excellence ofthe digital modulation systems to generate both Analog and Digitalemissions.

FEATURES: TV Transmitter driving unit with digital processor for ana-

log and/or digital emission standards (software defined) High performance (MER, Shoulders, Intermodulation…) Several configurations: Transmitter, Gap- filler, Regenera-

tive Repeater, Transposer, Trans-modulator… High reliability State-of-the-art technology

www.abe.it

The MTX Driving Unit is a compact professional exciter, suitablefor the integration in both analog and digital TV Transmitters,Transposers, Regenerative Repeaters, Transposers, Trans-modulators, Gap-fillers (DVB-T/H, DVB-T2, ISDB-T/Tb and othersoperating both MFN and SFN).

The equipment is fully contained in a single 19” 1U rack and iscapable, according to the RF power amplifier installed, to provideup to 5Wavg digital output, and 10Wp.s. in analog mode. Featuring a modular construction – with easily replaceable boardsand parts - the MTX exploits the advantages of latest componentsand mounting technologies to achieve high-reliability and compre-hensive system flexibility – all in a reduced footprint. Maintenance, control as well as parameter changes and settings,are simple and easy-to-perform operations.

The unit can be equipped with one or more digital processor boardsaccording to the calculation and processing capacity requested bythe TV standard/s implemented for the emission. For example, if the driving unit is used for analog multistandardTV emission (B, G, D, H, I, K, K1, M, N standard) or for one of thefirst generation digital TV standards (e.g.: DVB-T/H, ISDB-T…) justone digital processor board is enough. The digital processor board can store one or more different TVstandard without any firmware upgrade (software defined). If you need optional functions (like re-multiplexing, seamlessswitching and others) it is necessary to equip the unit with twodigital processor boards. For the DVB-T2 TV standard are neces-sary three digital processor boards.

A key function of the equipment is the digital linear and non-linearpre-correction with the possibility to store and recall up to 8 differ-

ent pre-settings. The linear pre-correction changes the amplitudeand group delay versus frequency to prevent the distortions mainlyintroduced by the output filter of the transmitter. The non-linearpre-correction introduces a pre-distortion in the amplitude andphase based on the level required to correct the non-linearity main-ly introduced by the power amplifiers, therefore giving the oppor-tunity to increase the output power, MER & shoulder performance. Optionally, for digital modulations, it’s possible to equip the “MTX”driving unit with the adaptive non-linear pre-correction modulewhich automatically provides the linearization.

The unit can manage up to 4 different inputs with “near-seamless”or, optionally, ”seamless” automatic switching.

Several interface types are available for different configurations: ADC (Analog to Digital Converter) for Video and Audio analog

inputs (for analog modulation standards) ASI (Asynchronous Serial Interface) Ethernet (T.S. over IP) able to receive MPEG transport streams

(encapsulation ProMpeg COP#3 rel.2) DVB-S/S2 receiver for reception from satellite or from a radio-

link transmitter and for configuration as trans-modulator or gap-filler. (The receiver can optionally support multistream and PLde-scrambling)

DVB-T/H terrestrial reception for configuration as a regenerativerepeater

The DTX can optionally be equipped with a CAM (ConditionalAccess Module) to decrypt encoded Transport Streams (i.e. fromthe DVB-S/S2 satellite receiver).

Event Logger (recording with date & time of all events ofalarms, power-on, fault conditions etc.) with storage of more than5,000 events and is downloadable through the transmitter’s WEBServer

Remote Upgrade Function for the control board firmware Email Client for the automated notification, via email to pre-

programmed 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 thecontrol centre can be established by means of a GPRS or UMTSmodem / router, a radio data-link or an ADSL or PSTN modem.

The optional digital processor can also provide re-multiplexing func-tions (with PID filtering, insertion / change of tables, etc.) and “seam-less” switching between two transport stream inputs; in this way,when operating in SFN mode, the driving unit doesn’t interrupt theemission when switches between input transport streams (from prima-ry to secondary or vice versa). The unit is equipped with a direct digital synthesis modulator withthe possibility to select any output frequency in the UHF band with1Hz resolution. The GNSS receiver option, specifically developed for the timing func-tion, provides time and frequency signals (1PPS and 10MHz) neces-sary for the synchronization of the transmitter when operating in SFNMode. This is a new concept Timing Reference GPS Locked genera-tor with unique special features, with proprietary algorithms, to preventnetwork de-synchronization (Holdover error recovery, Single satelliteoperation, Fast cold start-up, Zero cumulated error, etc.) and is avail-able in redundant configuration (double radio). Moreover, the reference high-stability “oven type” oscillator employedis capable of maintaining the synchronization over long periods whenthere is an intermittent signal from the GPS satellites (holdover func-tion). In analog transmission mode, with the GPS receiver option, theequipment can also operate in “precision offset” mode, to reduce co-channel interference. The “MTX” driving unit can operate in redundant configuration (1+1 –dual drive) by means of an external change-over unit. Additional features of the “MTX” driving unit also include: Comprehensive monitoring and protection circuits 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 isbuilt around a 32 bit micro-controller with the following key character-istics: 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 addi-

tion to RS485 Web Server with access protected by username/password (3 dif-

ferent levels of control) able to read/set all the equipment parame-ters
