DVB-S2 L-band 8PSK Modulator Full Comply with EN302 307 (DVB-S2) and EN300 421(DVB-S)
Descriptions
DVB-S2 L-band 8PSK Modulator which is a high performance modulator is developed according to the Europe satellite
communications system digital video broadcasting second-generation standard DVB-S2 (EN302307), the modulator
standard adopts more advanced channel coding techniques and higher order modulation combination, in the same
conditions it increases more transmission capacity than DVB-S, and can provide a more robust receive ability under the
same spectrum efficiency. The device's RF output is in the L- band, can directly form a complete set with satellite
communication system's digital TV transmitter. And downward compatible DVB-S's (EN300421) all kinds working modes
support local and remote configuration modulation parameters.
Features
l Fully compliant to EN302 307(DVB-S2 Broadcast mode) and EN300 421(DVB-S)
l Supports symbol rate of 1~30Msps(DVB-S2), 1~45Msps(DVB-S)
l Supports FEC rate of 1/2,3/5,2/3,3/4,4/5,5/6,8/9,9/10(DVB-S2), 1/2,2/3,3/4,5/6,7/8(DVB-S)
l 2 ASI Input, supports hot-backup online; DS3 input optional
l Excellent MER performance over 38db
l RF output range of 950~2150Mhz, 1Khz step
l LCD display, keyboard and network management
