Standard Features:
QAM Modulator with VHF & UHF Up-converter, supports DVB-C Annex A,B,C.
High Speed USB 2.0
Windows 2000, XP Drivers and API.
Accompanied by DVSStation2 Alitronika's Application Software.
Supports DVB According to Standard A1010 Rev1 and EN50083.
Modulation of Transport Stream files from Harddisk.
Modulation of Transport Stream from the ASI or SPI inputs.
All modulation processes are carried out by the hardware so that there is no load on the PC processor,
   So there is no need for an expensive high performance PC.
Bit rates from 14 MB/s to 65 MB/s.
Supports Burst or continuous modes, 188 and 204 packet sizes.
RF & IF Section are in metal enclosure for noise immunity and high performance
