DVB-H Modulator (RF out in L band)

NN6-1161RFL

DVB-H modulator with RF output within L-band

NN6-1161RFL DVB-T / DVB-H Terrestrial modulator performs broadcast quality COFDM modulation according to DVB-T standard and features a built-in RF Up Converter. RF outputs are filtered and agile within the L-band, covering the [1.4 GHz to 1.7 GHz], i.e. [1400 MHz to 1700 MHz]. It is a powerful means to perform field test, mobile receiver application development and validation, smart demonstrations.

It is optionaly possible to have a USB2.0 input on rear panel of the device to directly play an MPEG-2 Transport Stream from a PC, without needing professional stream player.

Applications:
     - DVB-T or DVB-H Broadcast in the 1.4 GHz to 1.7 GHz band
     - R&D development of DVB-T or DVB-H equipment
     - Test & validation of fixed or mobile receivers
      - Easy demonstrations and roadshows around TV on mobile
