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.

& (Q) Output.
DVB-ASI output for monitoring the modulated TS file.
Modes of operation
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
