Dexin NDS2406B DVB-S2 to DVB-T/T2 Modulator

General Description

NDS2406B DVB-T/T2 modulator is DEXIN’s all-in-one device which integrates demodulation, trans-mux and modulation in one case to convert signals into DVB-T/T2 RF output and IP output over UDP. The device equipped with 2 DVB-S/S2 tuner inputs, one GPS 10MHz input port and one 1PPS input port. The output modulated signals are to be received by TVs, STB and etc. This DVB-T/T2 modulator also simultaneously supports adaptive linear and nonlinear digital pre-distortion.

BISS function is also embedded to descramble programs from tuner input..

Key Features

l Support 2*S/S2 Tuner input

l IP (1*MPTS over UDP) mirror RF output

l Support MISO and SISO

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

l Supports non-linear and linear digital pre-distortion (DPD)

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

l Support LCD display and keyboard

l Support BISS descrambling

l Web-based Network management
