4-channel DVB-C modulator CRT1041M-C-02

4-channel DVB-C Modulator CRT1041M-C-02

CRT1041M-C-02 is a compact size 4-channel DVB-C modulator. Transport stream of four independent multiplexers come respectively to four DVB-ASI inputs of modulators .Two pairs of QAM modulated signals output as adjacent up-converted carriers. Central frequency of the first channel tunes in the range 48–850 MHz, and the other one is always shifted 8 MHz up. Modulation types of 16, 32, 64, 128 and 256QAM are supported. Set of 6.750, 6.875 and 7.000 Msps symbol rates are intended for 8 MHz channel spacing applications. Basically the device can be used in cable, MMDS or SMATV digital TV networks.
