SATELLITE UPLINK - MICROWAVE LINK DIGITAL MODULATOR The high quality, professional and cost-effective solution

ABE Elettronica is proud to present the ?DVM 1000/S-DSNG-S2? Modulator for digital satellite uplinks and terrestrial microwave links. The unit is a high quality, professional and costeffective solution built on ABE?s experience, gained over 30 years and developed employing ?state of the art? technology. Applications - Digital satellite Uplinks for Distribution, Contribution, DSNG / ENG Mobile news gathering; - Digital Microwave Links (Mobile and STL); Features - Compliant to: DVB-S standard ETSI EN 300 421; DVB-DSNG standard ETSI EN 301 210; DVB-S2 standard ETSI EN 302 307 for Broadcast and DSNG applications. Supports all modulation schemes (QPSK, 8PSK, 16APSK and 32APSK), all code rates (both mandatory and optional), CCM (Constant Coding and Modulation), normal FECframe, Dummy frame Insertion, all roll-off factors and null packet deletion/insertion - Synthesized IF output @ 70MHz or ?L? Band - Digital non linear pre-corrector to correct the amplitude and phase vs. level distortions generally introduced by the high power amplifiers (HPAs) so increasing output power, MER and shoulders performances - #2 Transport Stream inputs with manual or automatic near seamless switching - Automatic Transport Stream adaptation with PCR time re-stamping - User-friendly local control with front panel LCD display and keypad - RS485; Ethernet 10/100 Base-T (SNMP and web server support) remote control interface option. Featuring modular construction - with easily removable boards and modules, the unit exploits the advantages of SMD technology to achieve high reliability and comprehensive system flexibility - all at reduced size. The modulator board, the key component of the DVM1000/S-DSNG-S2, is based on a single FPGA and is compliant with the ETSI DVB-S standard EN 300 421; DVB-DSNG EN 301 210; DVB-S2 EN 302 307 for Broadcast and DSNG applications. A key function of the modulator is the digital nonlinear pre-correction with the possibility to store and recall of several setups. This function allows to correct the amplitude and phase vs. level distortions introduced by the high power amplifiers (HPAs), so increasing output power, MER and shoulders performances. Two input interfaces are available in order to feed the modulator: - #2 ASI interfaces, capable of near seamless switching - GbE interfaces with up to 2 inputs for MPEG TS over IP (ProMpeg COP#3 rel.2) The Modulator can be supplied with IF 70MHz or ?L? band synthesized output frequency. Features also include a 10MHz reference clock and the power supply for the BUC (Block Up Converter). Optionally, a ?oven? high-stability 10 MHz reference oscillator locked to GPS signal can also be supplied. The DVM 1000/S-DSNG-S2, combined with a BUC and a parabolic antenna for the chosen frequency range (usually Ku band ? 14 to 14.5GHz ? of C band 5.85 to 6.43GHz), makes a complete satellite uplink solution. Another application of the DVM 1000/SDSNG-S2 is as modulator for synthesized terrestrial digital microwave links. The innovative interface, management and control board of the equipment is built on a 32 bit micro controller. Key characteristics are: -LAN interface (Ethernet 10/100 Base-T ? RJ45 connector) in addition to RS485 - User friendly web server securely protected with username / password (with 3 different control levels) able to read and set all equipment parameters for local and remote management and diagnostics (TCP/IP protocol) - SNMP AGENT able to send alerts (traps), read equipment parameters (e.g. the modulator status through the ?get? command), manage the equipment (e.g. to reset through the ?set? command) - Control board software (firmware) remotely upgradeable - Event logger (register all alarms, switch-on, faults, etc. with date and time log) with the capacity to store over 5,000 events that can be downloaded through the embedded web server. - e-mail client to automatically notify, via e-mail (to pre-registered e-mail addresses) variations in the alarm conditions. A graphic display on the front panel allows onsite control and adjustment of the most important
