Product Description

 QAM6248 is a new generation of Multi-functional QAM modulator, which can receive one
channel of TS from IP interface or up to 16 channels of TS from ASI interfaces, and then
multiplex, scramble and multi-modulate it with channel coding, as well as four channels of IP
loop output.
It adopts our newly developed functions such as "Module Management", device scrambling, and channel modulation. The flexible customization and high expansibility can satisfy the user's current and future DTV system requirements.
The product is mainly applied to the DTV network head end room, edge of DTV backbone network, and DTV branch head end room.

Feature:
Support ITU-T J.83A/B/C,output frequency range: 54MHz ~ 870 MHz
Up to 6/8/16 ASI or 8 fta dvb-s2 RF ports or GbE IP port in per chassis with Max.4 agile QAM channelsout
Simultaneous outputs via MPTS over GbE IP and RF Port
Capable of working with 16QAM, 32QAM, 64QAM, 128QAM, 256QAM modulation methods
