Netmod for HDc

DVB-T/T2 modulator

NetMod  is ENENSYS’ standalone multistandard modulator to broadcast digital TV services over DVB-T or DVB-T2 networks.

NetMod broadcast modulator  provide a cost effective and high quality solution for broadcast network operators, system integrators and transmitter manufacturers aiming to deploy digital TV services over DVB-T or DVB-T2.

The NetMod offers high grade broadcast IF and RF output level. It includes automatic Digital Pre-Correction (DPC) to optimize the transmision efficiency.  It operates in MFN and SFN environments. A built-in GPS receiver can be included to ease broadcast operation.
