CATV Modulator 16 Channel
CATV modulator 16 channel
CATV modulator 16 channel is a 4RU rack mounted chassis that allows for installation of up to 16 pieces microprocessor-controlled fixed mini modulators. Built-in active combiner eliminates unnecessary cabling and potential connection problem and ensures high output level. All modulator cards are perfect factory set to desired channels and proper offset.
FEATURES of CATV modulator 16 channel
1. The vestigial side-band selectivity allows maintenance free adjacent channel configuration
2. Two cooling fans for long life performance
3. 45dBmV combiner output level, no need extra combiner
4. SAW(surface acoustic wave) filtering on IF for superior in band C/N
5. Front panel access controls enables easy setup
6. Available in NTSC or PAL configurations
