WORK Microwave SDM2 DVB Satellite Broadcast Modulator

Fully compliant with DVB standards, the DVB Satellite Broadcast Modulator supports a wide range of DTH broadcast, video contribution, and distribution applications over satellite.

Through an advanced feature set, the broadcast modulator helps operators get the most out of expensive satellite bandwidth, optimize data transport, and considerably improve satellite signal quality.

Innovative features include Carrier ID, DVB-S2 multistream, TSoIP, and wideband (up to 80 Mbaud). In addition, the DVB Satellite Broadcast Modulator platform supports next-generation DVB-S2X, providing operators with a future-proof solution.

MPEG transport stream input – L-band or IF output

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 combination with external multiplexers and encapsulators.

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.

VideoACM

An integrated VideoACM controller provides adaptive or variable FEC and modulation setting for point-topoint or point-to-multipoint Transport Stream transmissions.

Predistortion

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.

Flexibility, backward compatibility

Mode adaptation, FEC encoding, and modulation is compliant with the DVB-S2/S2X standard ETSI EN 302307. QPSK, 8PSK, 16APSK, 32APSK and 64APSK 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.
