4 channel COFDM(DVB-T) Modulator RF outputs; 4 DVB-S2/DVB-T2 Demodulator; 8 MPEG-2 Encoders; 4 multiplex 4 scramblers
COFDM(DVB-T)Modulator
In addition to COFDM modulation, the COFDM Modulator combines with demodulator, DVB multiplexer and scrambler (option). Supports 1 tuner input and 2 ASI inputs, and then Re-Multiplex, scramble and modulates the input signal to COFDM (DVB-T) signal. High-performance MER, CNR, phase jitter and phase PER.
