NetMod-DVB-T2 broadcast modulator has been designed to provide a cost effective and high quality solution for broadcast network operators, as well as for system integrators facing this standard. NetMod-DVB-T2 conception ease also the integration in any kind of system thanks to an intuitive Graphical User Interface and value-added features.

NetMod-DVB-T2 is fully DVB-T2 standard compliant in mono-PLP, and can handle as option the DVB-T/H standard for more network deployment flexibility.

NetMod-DVB-T2 offers various high grade features such as MFN+SFN, T2-Modulator Interface over ASI and IP, MISO, PAPR reduction, Digital Pre-Correction (optimizing overall broadcast transmission), built-in GPS receiver option, etc...

On top of that, NetMod-DVB-T2 is also featured with a set of modes that will ease installation and maintenance for network operators and broadcasters, as well as a set of configurable failover behaviour to secure regular broadcast operations.
