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. Extensions 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.
The DVB-S2 calculator can be downloaded below (version 2.17)
Note: The Excel sheet is protected in order to guard the source data. However, users are allowed to create their own formulas in the calculator and change the text and layout. We encourage downloading from Newtec’s website as this gives you a chance to register and be notified automatically when new updates become available.
