COFDM DVB-T2 Modulator
#1
[Image: DVB_T2-Modulator.jpg]

Overview
CEL-5105 DVB-T2 Modulator complying with DVB-T2 (EN302 755) standard channel coding and modulation parameters. This modulator can effectively make use of the ground spectrum resources and make it possible to provide reliable signals for fixed, mobile and portable devices, supporting FEC and RS correction and encoding, which makes it convenient to connect other analogue and digital signals, compared with DVB-T, the channel capacity is increased by 30% under the similar carrier to noise ratio (CNR) threshold. It is suitable for HFC, MMDS and broadband digital system.

Moreover, this device can be upgraded and controlled through network system, which allows it to be widely used in setting up digital broadcasting network and provide good signals for scientific laboratory and DVB-T2 STB. 

Features 
- Comply with DVB-T2 standard
- ASI input
- PID filtering and re-mapping
- LCD/Keyboard control by front panel and network management by Ethernet
