DVB Satellite Broadcast Modulator
70/140 MHz IF Output
L-band Output
Fully compliant with DVB standards, the DVB Satellite
Broadcast Modulator supports a wide range of DTH
broadcast, video contribution, and distribution
applications over satellite.
point or point-to-multipoint
Through an advanced feature set, the broadcast
modulator helps operators get the most out of
expensive satellite bandwidth, optimize data transport,
and dramatically improve satellite signal quality.
Broadcast Predistortion and Extended Predistortion –
operating in the background during regular
transmission – mitigates the negative effects in the
filters and amplifiers of satellites by automatically
compensating for linear and non linear distortions.
Subsequently the satellite link can be operated with
less back off/higher power and a higher signal-tonoise ratio increases beam coverage ensuring higher
throughput and availability for the satellite operator.
Innovative features include Carrier ID, DVB-S2
multistream, TSoIP, and wideband (up to 80 Mbaud).
In addition, the DVB Satellite Broadcast Modulator
providing operators with a future-proof solution.
MPEG transport stream input – L-band or IF
The modulator accepts MPEG transport streams on
ASI, SPI, or TS over IP inputs from a video encoder or
MPEG multiplexer and provides a DVB-S, DVB-S2 or
DVB-S2X modulated carrier output between 50 to
180 MHz or L-band. Additionally a baseband frame
input is available for VCM and ACM modes in
High signal integrity
Low spurious emissions make the modulator perfect
for use in environments with demanding requirements,
like high-power video uplinks. Sophisticated
temperature compensation guarantees output stability
over a very wide temperature range.
An integrated VideoACM controller provides adaptive
or variable FEC and modulation setting for point-to-
Flexibility, backward compatibility
Mode adaptation, FEC encoding, and modulation is
compliant with the DVB-S2/S2X standard ETSI EN
302307. QPSK, 8PSK, 16APSK, and 32APSK
modulation is available. For backward compatibility,
the modulator also supports BPSK, QPSK, 8PSK,
16QAM modulation according to the DVB-S standards
ETSI EN 300421 and 301210. Using the modulator,
carriers with very low symbol rates (e.g., 8 ksps) up to
80 Msps can be transmitted.
Operating and control – easy integration into
your system
The modulator can be operated via push buttons on
the front panel using intuitive display menus or via
remote control (RS232, RS422/485 and TCP/IP over
Ethernet). Detailed monitoring of the system status
and a summary alarm output (dual change over switch
contacts) are provided. For the remote control
addressable, packet-based commands are used.
Remote monitoring and control through SNMP, and a
Web browser interface is available.
