YCTD 5900 QAM modulator
The YCTD 5900 QAM modulator is the ideal cost effective solution to DVB-C broadcasting.
With its agile frequencies from 54 up to 860 MHz and adjustable level, the YCTD 5900 QAM modulator is the perfect solution for your digital head-end component, providing QAM TS and RF up conversion functions in a single module.
ASI input is compatible with all existing DVB multiplexers, encoders, or digital receivers. The QAM modulation supports constellations of 16, 32, 64, 128, 256 levels, making it possible to move up to 54Mb of SPTS / MPTS streams across the cable network on the selected channel.
- Operates in DVB.
- ASI signal input and a digital QAM signal output in 16/32/64/128 or 256 QAM mode.
- Front panel LCD for monitoring, data display and setup.
- High MER (Modulation Error Rate) ensures a low bit error rate.
- Switching power supply 90VAC-260VAC, 50Hz/60Hz.
- Standard 19' rack-mount for installation.
- SAW filtered IF out/in loop.
- 47-862MHz output frequency agility.
- 60dBmV output level with hybrid module IC.
- Output level adjustable by a 15dB range.
- Low out-of-band noise and high VSB attenuation.
- Double PLL synthesized channel control.
- Ability to control multiple and daisy chain QAM modulators with our Monitoring & Control Software.
