DVB-S/S2 8PSK/APSK/QPSK Modulator
Model No:GQ-3780
GQ-3780 is a professional DTV Satellite Modulator which can receive the DTV transport streams from ASI interface, RS-530/422 interface (optional), G703 interface (optional), LVDS interface (optional), and then modulate the signals by DVB-S/S2 standard. It finally outputs the signals after up conversion at mid-frequency or L-band via RF or IF outputs. This device has outstanding RF performance which can be used in satellite DTV network head-end systems.
Main Features:
- Input rate range: 8 Kbps~140 Mbps
- Modulation support BPSK, QPSK, OQPSK, 8PSK, 16QAM
- Data input interface: ASI, optional interfaces: RS-530/422, G703, LVDS
- Support 70 MHz/140 MHz IF output and 950~2100 MHz L band output
- Support time-delay balance of 70 MHz/140 MHz IF group
- Available FEC mode: 1/2, 3/4, 5/6, 7/8
- Remote monitoring methods support USB, Ethernet, RS-232, RS-485
- Centralized Web/SNMP management and remote upgrade/maintenance
- Support monitoring of operation temperature and power supply status
