Product Description


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.


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.
