Overview
The DVU 5000 DVB-S2 modulator utilizes the innovative UBS Universal Waveform engine, supporting all world standards for satellite, mobile and terrestrial digital broadcasts. This open architecture design enables carriers to take advantage of a proven, robust platform, while designing networks to meet current and future broadcast standards. This series incorporates all of UBS high performance signal processing stages including integrated linear and non-linear pre-correctors. Full remote management and control as well as remote irmware and waveform upgrades are provided.

Application
The core function of the DVU 5000 is to modulate a MPEG-2 transport stream (ASI input) onto a DVB-S2 compliant spectrum (output) in accordance with the rules for channel coding and modulation speciied in the DVB-S2 standard EN 302 307.

RF Output
Using the latest technology, UBS has developed a direct conversion process that allows the modulator to provide an IF out put from 50 MHz to 180 MHz, with superior shoulder and MER. Optionally, the modulator can be conigured with an L-Band output from 950 MHz to 2150 MHz. The output level is adjustable from –10 dBm to 0 dBm (optionally from 0 to +10 dBm) with a step size of 0.1 dB. The user can set the polarity of the spectrum to Inverted or Non-inverted as required.
