Overview

The DTX1000U is a compact solid-state Transmitter/Repeater system, designed to provide Digital Terrestrial Television Broadcasting service over the UHF frequency band from 470 MHz up to 860 MHz at the output RF power level of 120 Watts.

The DTX1000U performs conversion of the input MPEG transport stream to COFDM modulated IF signal, converts this IF signal into RF signal at required transmit channel frequency within the UHF band and provides RF signal amplification up to required output power level. The power level stability at the transmitter RF output is maintained by internal automatic level control loop.

The DTX1000U can be configured to support any one of the existing modulation standards, currently accepted for Digital TV Broadcasting: DVB-T/H and DMB-T.

The operation parameters of the Transmitter are monitored and controlled by embedded system controller. The Transmitter parameters monitoring and setting could be performed from the front panel display or using remote control interfaces (Ethernet, SNMP or RS232).

With addition of optional DVB-S/S2 Receiver/Demodulator module, the DTX1000U could be configured as a Terrestrial Repeater, which receives the input data stream from the satellite downlink and re-broadcast this signal in COFDM format.

All the Transmitter/Repeater system components are enclosed in a standard 19” rack mount chassis, occupying only 3 “RU” of the cabinet space. The transmitter is forced air cooled using four compact high performance fans installed on a front panel of the transmitter enclosure.
