Standard Features:

Combined COFDM, QAM & ATSC Modulator with VHF & UHF Upconverter.

High Speed USB 2.0

Windows XP, Vista, Windows 7 & Windows 10 Drivers + SDK & Linux Drivers.

Accompanied by DVSStation3 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.

Supports Burst or continuous modes, 188 and 204 packet sizes.

Bitrates:
- DVB-T/H : 4.98 MB/s to 31.67 MB/S.
- DVB-C : 14 MB/s to 65 MB/S.
- ATSC : 10.76 MBaud to 19.30 MBaud.
