Standard Features: |
 |
|
|
QPSK Modulator and UHF Up-converter, supports
DVB-S2X, 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 an External DVB-ASI source.
High Speed USB 2.0
Windows
XP, Vista, Windows 7 ( 64bit ) & 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
from an external source via 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 one board
memory of the AT3900USB. These parameters could changed by the user
ant any time via the USB or RS232 interfaces.
The device modulate TS files from an incoming DVB-ASI streams.
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.
