Descriere

The MO-170 is a general purpose DVB-T and DVB-H modulator contained in a 19" 1U chassis, fully compliant with the DVB-T/H specification ETSI EN 300 744 v1.5.1. The unit has three selectable MPEG-2 TS inputs (two serial ASI inputs and one parallel SPI input). The input to the modulator is an MPEG-2 Transport Stream (TS) in DVB-SPI or DVB-ASI formats. The outputs from the unit are the COFDM modulated DVB-T/H signal upconverted to IF and RF.

The modulator has been designed to achieve the maximum performance yet at an affordable price. The MO-170 supports 2k, 4k and 8k modes, hierarchical transmission and it can operate in Multi Frequency Networks (MFN). The digital coding and modulation process is implemented with programmable logic devices using PROMAX proprietary IP. This makes the design highly flexible, allowing to tailor it to any particular application.
