DVB-S2 Calculator with S2 Extensions

April 23, 2013 | By More

Newtec has launched a beta version of its next generation DVB-S2 calculator, which -among other additions- includes useful options for DVB-S2 “extensions”. The new DVB-S2 calculator is an Excel-based tool that gives an overview of the performance data and input for link budgets when using DVB-S and DVB-S2 modulation over satellite.

DVB-S2 S2 Extensions are Improvements to the original DVB-S2 standard that provide satellite service providers with improved system performance and granularity. DVB-S2 extensionsExtensions include:

  • Smaller Roll-Offs
  • Advanced Filtering
  • Supporting Different Network Configurations
  • Increased Granularity in MODCODs
  • Higher Modulation Schemes up to 64APSK
  • Linear and non-linear MODCODs
  • Wideband Support up to 72 Mbaud

When comparing the current DVB-S2 standard against the full implementation of S2 Extensions (activating smaller Roll-Offs, advanced filtering, 64 APSK and wideband) staggering efficiency gains up to 64% can be achieved for professional applications over satellite (TV contribution and distribution) and up to 20% efficiency increase for DTH.
