DMB-2028 DVB-T modulator is designed to meet the most demanding of today’s digital terrestrial TV broadcast market, which is applied especially to the medium and small terrestrial digital TV systems and enterprises. It supports DVB-T whole working modes，hierarchical mode as well as VHF and UHF band frequency agile signal output. With high quality RF signal, it directly drives the low power digital TV transmitter, and contains such three test modes as NULL insertion, PRBS sequence, test stream, which supply comprehensive and reliable DVB-T signal source system for R&D company or manufacturer. DMB-2028 DVB-T modulator is the cost-effective modulator.
