QUICK CONFIGURATION GUIDE
1. INTRODUCTION
The DT-101B/102B modules (single/dual) are COFDM modulators
compatible with DVB-T standards. The DT-101B module has an ASI-TS
input and the DT-102B module has two ASI-TS inputs. Both them have an
RF output in the UHF band (from 170 to 650 MHz in the V-option).
The DT-101B module generates a DVB-T output from an ASI –
Transport Stream input. The output signal has excellent power and quality
levels so that it can withstand significant degradation through wiring,
splitters, amplifiers, etc.
The DT-102B has the functionality of two DT-101B units and
includes two ASI-Transport Stream inputs and one single output with two
DVB-T combined channels. Its internal combiner delivers high C/N ratio.
Note that when there is a double module (DT-102B), each single
element will be independent and will have its own configuration.
Among the practical applications of this module are the possibility to
choose the channel frequency and the output level, to remove video, audio
or data services from the original signal, the restoration of the quality of a
weak signal or the possibility to move DVB-T channels from one frequency
to another, to avoid degradation of the signal or overlapping on other
channels.
After going through this process, the signal of the DVB-T module can
be inserted into a television distribution network, with the advantages of
robustness and high quality offered by the digital technology.
