ZJ2406B DVB-(T) Modulator
Outline
ZJ2406B DVB-(T) modulator is our all-in-one device which integrates demodulation, trans-mux and modulation in one case to convert signals into DVB-(T) 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) modulator also simultaneously supports adaptive linear and nonlinear digital pre-distortion.
BISS function is also embedded to descramble programs from tuner input.
Features
● Support 2*S/S2 Tuner input

● IP (1*MPTS over UDP) mirror RF output
● Support MISO and SISO
● High performance output: MER>43dB, shoulder level>56dB
● Supports non-linear and linear digital pre-distortion (DPD)
● Constant temperature crystal oscillator, as high as 0.1ppm stability
● Support LCD display and keyboard
● Support BISS descrambling
● Web-based Network management
