OTV-MT26 DVB-T2 Modulator


Overview: 

OTV-MT26 DVB-T2 modulator is our new product developed complying with the DVB-T2 standard. With its advanced modulating technology, this modulator can effectively make use of the ground spectrum resources and make it possible to provide reliable signals for fixed, mobile and portable devices. Compared with DVB-T, the channel capacity is increased by 30% under the similar carrier to noise ratio (CNR) threshold.


OTV-MT26 DVB-T2 modulator also supports single-PLP and multi-PLP (option) to receive T2-MI from DVB-T2 gateway through its ASI and IP port. (This function is also option.)

Moreover, OTV-MT26 DVB-T2 Modulator can be upgraded and controlled through network system, which allows it to be widely used in setting up digital broadcasting network and provide good signals for scientific laboratory and DVB-T2 STB.


Key Features:

  • 4 ASI input ports (for 1 channel TS input with 3 ports for backup)

  • DVB-T2 RF output

  • TS over IP input (UDP); T2-MI over IP input (Option)

  • Fully complying with EN302 755 standard

  • 10MHz input/loop out, 1PPS input/loop out

  • Supports single PLP, multi-PLP (Option) , Support MISO and SISO

  • Support QPSK/16QAM/64QAM/256QAM (normal or rotated)

  • Support TS format: T2-MI (Option) or TS (Mode A)

  • High performance output: MER>43dB, shoulder level>56dB

  • Output signal bandwidth: 5M, 6M, 7M, 8MHz

  • Support MFN and SFN (Option) net mode

  • Supports non-linear and linear digital pre-distortion (DPD)(To Video) for optional.

  • RF output level: -25~+3 dBm, 0.1db stepping

  • Constant temperature crystal oscillator, as high as 0.1ppm stability

  • Keyboard operation and LCD display

  • Web Network management system(GUI)
