Overview
Combines Advantech Wireless’ powerful DVB-S/S2
modulator and demodulator in a single 1 RU chassis.
Powerful Forward Error Correction (FEC) choices compliant
with DVB-S, DVB-DSNG, and DVB-S2.
The DVB-S2 implementation includes 16APSK/32APSK and
both 16k (SHORT) and 64k (NORMAL) FEC Block sizes
64QAM support is backed with powerful LDPC BCH
implementation (4th generation turbocode) to provide
155Mbps high efficiency link.
Also supports eTPC Turbo code for lower speed applications
(up to 20Mbps).
Supports standard Viterbi and Reed Solomon.
Symbol Rates from 32ksps to 45Msps Symmetrical or
asymmetrical support.
Modulation and FEC options are all “soft key” controlled
allowing simple field upgrades
Excellent spurious performance
L Band: 950 to 1750 MHZ IF ranges, or 950 to 2000 MHz IF
ranges and/or 70+/-18Mhz or 140+/-36Mhz IF ranges

Applications
Although being designed as a universal Modem, this unit is
particularly suited for the following application fields:

Digital Video distribution Broadcast

Digital Satellite News Gathering

Corporate (bi-directional ) networks

Contribution broadcast networks video exchange

IP traffic to ISP’s

IP backbones and cable restoration

Primary Distribution of terrestrial networks
Advantech Wireless' AMT 75e is a multi-purpose High
Speed Satellite modem which is a particularly versatile and
effective solution for any broadcast environment. The
emergence of HD and 3D content demands more data and
the AMT 75e handles all higher DVB-S2 modulation
schemes.
The AMT 75e achieves a Bandwidth-efficient transmission,
from 30% to 150% gain when compared to the old DVB-S
performance. When compared with the old FEC coding, the
LDPC (Low Density Parity Check) and BCH (BoseChaudhuri-Hocquenghem) coding is known to be far more
robust, giving a performance as close as 0.7 dB from the
famous Shannon limit.
In practice, this means your capital investment is
significantly reduced due to the decreased bandwidth
requirements.
The AMT-75 modem is also designed using Software
Defined Radio techniques to ensure unrivaled flexibility:
Any future technology evolution or new features can be
introduced by simple FW upgrade. A future-safe investment
is hereby guaranteed.
When used for broadcast applications, the AMT75 offers a
flexible choice of data interfaces. These are up 8 (4 are
standard) ASI inputs which can be aggregated into a DVBS2 single MultiStream carrier (CCM/VCM/ACM).
Next to these, an GbE IP interface is also available with
optional MPE and GSE encapsulation. Going beyond the
standardized DVB-S2 specifications, Advantech also offers
extra improvements for even greater BW efficiency, such
as a roll-off factor of 15%, 64QAM modulation, 4k block
size (yielding even lower latency), and eTPC Turbo code
for lower speed applications. (Telco use mainly)
Obviously, the unit is also backward compatible with older
modulation schemes such as DVB-S and DVB-DSNG. The
demodulator part is quasi 100% the mirror of the modulator
part: It is performing ISI filtering for DVB-S2 MultiStream
applications, Decapsulating the IP stream(s), and handling
all standardized modulations.

AMT 75e DVB-S/S2 High Speed Broadcast Modem
Overview (Cont’d)
When used in a redundant configuration, the unit has a built-in detection and triggering system, requiring external switches
only, rather than a complete external redundancy system. This offers the flexibility of being totally independent of the
redundancy configuration, which can be varying from 1+1 to e.g. 10+1.
Last but not least, this design has been proven to be one of the most reliable products on the market, while the unit price is
very comparable with the DVB-S2 gain described above. More details can be found on our Modulator (SBM75e) and
Demodulator data sheets (SBD75e).
