DVB-S S2 Modulator

FNJ-D1103 satellite DVB-S/S2 modulator is compliant to the available standards for Digital Video Broadcasting over Satellite (DVB-S2 EN 302307, DVB-DSNG EN 301210, and DVB-S EN 300421).

The availability of the modulator in a wide range of symbol rates, code rates and modulation schemes makes the FNJ-D1103 DVB-S/S2 modulator very useful in different applications. Supporting from various input signals and producing IF band signal (50- 90 MHz) and L-band signal (950 - 2150 MHz) makes it suitable for various applications.

All control and monitoring parameters are available locally on the front panel (LCD display & keyboard) and remotely through a web interface (HTTP/ SNMP) or through the RS-232/RS-485 ports.

APPLICATIONS

Fanamoj DVB-S/S2 modulator can be used in various applications such as broadcasting, distribution or contribution of Digital TV (HDTV/ SDTV) signals, Digital Satellite News Gathering and other applications.
