Digital Headend Equipment
WK-2406B DVB-(T) modulator
WK-2406B DVB-(T) modulator is Wolck’s 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.
