PureDefinition DVB-T/H Re-modulator

The PureDefinition™ DVB-T/H re-modulator presents a standalone rack mount solution for DVB-T/H signal retransmission adapted to the most demanding terrestrial signal propagation environments. Its state of the art design enables operation in variety of broadcasting network configurations as well as remote areas with extremely weak signal reception. It is able to fully exploit build-in signal redundancy to deliver completely restored signal with leading market RF performance.
PureDefinition DVB-T/H Re-modulator
Apart from signal regeneration the PureDefinition™ DVB-T/H re-modulator features received signal monitoring, decoded transport stream transmission, signal quality evaluation and channel characteristics measurements in order to give an operator real time insight into equipment performance during on-site installation and operation phase.
The re-modulator signal pre-correction functionality is based on years of signal processing experience, and developed with contributions from transmitter manufacturers, to provide the best possible performance in high power amplifier linearisation and antenna filter compensation. Optional adaptive pre-correction functionality allows for optimum performance and effortless manufacturing process.
Among different hardware and firmware configurations global synchronization offers synchronized signal regeneration from a large number of transmission sites and allows the use of over the air signal distribution.
