Product Overview

Use this module on its own or in conjunction with your computer's processor to support a broad range of modulation tasks.

 

Key Features:

  • QPSK Modulator and UHF Up-converter, supports DVB-S2, DVB-S & DVB-DSNG.
  • Re-Mux function to reduce bitrate for trans-modulation.
  • On board Compact Flash Memory to play Transport Streams without a need for an external source.
  • Stand alone operation. No PC needed. Modulation of TS files from On Board CF or External DVB-ASI source.
  • High Speed USB 2.0
  • Windows XP, Vista, Windows 7 & Windows 10 Drivers + SDK & Linux Drivers.
  • Accompanied by DVSStation4 Alitronika's Application Software.
  • Supports DVB According to Standard A1010 Rev1 and EN50083.
  • Modulation of Transport Stream files from Hard disk.
  • Modulation of Transport Stream from an external source via DVB-ASI input.
  • 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.
  • Interfaces:
    • RS232 for control of Settings & Parameter.
    • US2.00 for both Settings & Data transfer.
  • Input:
    • DVB-ASI input. 
  • Output:
    • RF Output.
    • IF (I) & (Q) Output.
    • DVB-ASI output for monitoring the modulated TS file.
  • Modes of operation:
    • USB Mode: In this mode the AT3900USB operates just as a standard USB based device. The Modulation and IF/RF parameter can be set via the application software, DVSStation4. The Transport Streams could be entering the device via the USB interface or via an external DVB-ASI source. A Re-Mux function could be used to Filter out unwanted PIDs to reduce the bitrate of the TS file or the Incoming DVB-ASI Transport Streams.
    • Stand Alone Mode: In this mode the device no longer requires a PC for its operation. Any Transport Streams from the DVB-ASI input is modulated according to the parameters set by the user. The modulation, If & RF parameters are stored on the on board memory of the AT3900USB. These parameters could changed by the user ant any time via the USB or RS232 interfaces. If there are no incoming DVB-ASI streams, the device modulates from the TS files recorded on its ON BOARD COMPACT FLASH memory. In this mode of operation, it is possible to have UNINTERRUPTED modulations of a MPEG Transport Streams, having RF ( 950 to 2150MHz ), IF ( both I & Q ) & DVB-ASI outputs available at the SAME TIME, 24 Hours a day, 7 days a week without a PC.

Applications

Targeted for Digital Video Professionals, Sophisticated End Users and OEMs the AT3900USB is an ideal solution for a number of applications such as:

  • Development Tools for DVB-S2/S Receiver R&D.

  • IP to DVB Gateway.

  • DVB-S2/S Transport Stream Generation.

  • Stand alone QPSK signal generator for Test & Validation.

  • Demonstration and Trade Shows.

  • DVB-S2/S output for OEM product.
