The new DVB-T DFX TITANIUM series is a broadcast digital transmitter
supporting MFN and SFN architectures. This series is designed as high
performance-compact system suitable for low and medium powers,
available from 2.5W to 700W. It includes: DVB-T exciter DX UM series,
an eventual power amplifier DF series, an output filter compliant with
the emission mask specification required and 19” standard rack
cabinet. The exciter, built in 3HE cabinet, integrates the COFDM
modulator which could be easily set by front panel or by USB port. High
efficiency amplifier, based on latest LD-MOS technology, offers great
linearity and excellent performances, also thanks to switching power
supplies. Every device is equipped with a LCD meter display to control
all operating parameters and remote control interface. The modular
construction of the equipment makes this transmitter family very reliable
and facilitates support and control procedures. It can be friendly
configured as Dual Driver or Dual Cast transmitter.

La nuova serie DFX TITANIUM è un sistema di trasmissione
professionale che supporta le architetture DVB-T MFN e SFN,
sviluppata per soluzioni compatte ad alte prestazioni, per apparati di
piccola e media potenza. Sono disponibili con potenze di uscita da
2.5W a 700W. La configurazione include: exciter DVB-T serie DX UM,
eventuale amplificatore di potenza serie DF, filtro di uscita e rack
standard 19”. L’exciter, allocato in un cabinet 3HE, integra il modulatore
COFDM che può essere facilmente settato tramite pannello frontale o
porta USB. Gli amplificatori ad alta efficienza, basati su transistor LDMOS di ultima generazione, offrono un’elevata affidabilità e prestazioni
superiori, grazie anche agli alimentatori “switching” ad alto rendimento.
Ciascun dispositivo è provvisto di interfaccia per il controllo remoto e di
un’unità display multifunzione per il monitoraggio di tutti i parametri di
funzionamento. La costruzione modulare facilita le operazioni di
controllo e manutenzione. La versatilità della struttura permette di
configurare agevolmente il trasmettitore in dual cast o dual driver.
La nueva serie de transmisores digitales DFX TITANIUM està proyectada
como un sistema compacto de alta calidad disponible para baja y mediana
potencia de salida de 2.5W a 700W. Los transmisores TITANIUM están
preparados para trabajar en redes digitales MFN y SFN e incorporan las
últimas y más novedosas tecnologías, ofreciendo una inmejorable relación
prestaciones - coste (CAPEX / OPEX). El transmisor incluye: el excitador
DVB-T serie DX UM, eventual amplificador de potencia serie DF, filtro de
salida y 19" estàndar cabinet. El excitador digital, alojado en un bastidor de
3HE, integra el modulador COFDM que puede ser seleccionado tramite el
panel frontal o a travès de la puerta USB. Los amplificadores estàn basados
en transistores LD-MOS de ùltima tecnologìa de alta densidad de potencia
que proporcionan un elevado rendimiento energético garantizando la
màxima calidad y fiabilidad. Todos los amplificadores estàn provistos de
fuente de alimentaciòn tipo « switching » de alta eficiencia. Una pantalla LCD
permite monitorear los paràmetros de funcionamiento. El aparado està
equipado tambièn con interfaz para control remoto. El diseño compacto y
modular y su elevada eficiencia energética facilitan las operaciones de
control y mantenimiento. Su versatilidad permite configurar con facilidad el
sistema en transmisor dual cast y/o doble excitador.
