Vortex II
ATSC 3.0 / ATSC 1.0 High-End Exciter
Vortex II is a highly optimized and unique platform supporting ATSC 1.0 and ATSC 3.0 Terrestrial TV standards. It meets manufacturers’ demands for integrating a “ready-to-use” and straight-forward high-end exciter within their new Transmitter designs as well as broadcasters’ requirements to upgrade their existing transmitter for the Spectrum Repack.
Highlights
ATSC 1.0 / ATSC 3.0 Standards
Vortex II exciter is already in use across the USA for powering ATSC 3.0 commercial deployment and many projects linked to the US Spectrum Repack, where its dual cast capability is a key feature for the switching from ATSC 1.0 to ATSC 3.0.
Up to 8 PLPs & 2 Subframes
As the most powerful ATSC 3.0 modulator/exciter on the market, Vortex II supports up to 8 PLPs / 2 Subframes as well as MFN and SFN broadcast to match any requirements.
Adaptive Precorrection process
Vortex II features the latest state-of-the-art Digital Adaptive Pre-correction (DAP) circuits achieving unequalled performances thanks to the Green Adaptive Processing (GAP©). As a result, very high level of MER and shoulders can be reached with less power consumption.
Automatic Gain Control
Based on its real-time power measurement probes (Forward & Reflected powers), Vortex II can control/adjust your Transmitter output power thanks to its smart Automatic Gain Control (AGC).
