TeamCast Vortex II

ATSC 3.0 / ATSC 1.0 High-End Exciter

Vortex II

Vortex II is as a very optimized and unique platform supporting both ATSC 1.0 and ATSC 3.0 terrestrial TV standards. It meets transmitter manufacturer’s demand for integrating a “ready-to-use”and straight-forward high-end exciter within their new ATSC 1.0/3.0 transmitter designs. It also meets broadcasters’ demand for upgrading their existing transmitter using a high-end and cost-effective exciter.

Applications

Vortex II
  • Straight-forward integration in a new ATSC 3.0 transmitter design dedicated to early tests & trials and to commercial roll-outs
  • Update/recycle of existing ATSC 1.0 transmitters within the US Repack process
  • Transmitter update to make it ATSC 3.0 Ready

Highlights

ATSC 1.0 / ATSC 3.0 dual cast modulation core

Vortex II exciter is already in use across the USA for powering ATSC 3.0 pilot projects and many other projects linked to the Spectrum Repack, where its dual cast capability is a key feature for the switching from ATSC 1.0 to ATSC 3.0.

Straightforward integration within transmitter

Fully controlled via a friendly WEB GUI and via SNMP, Vortex II features some very unique functionalities dedicated to ease the integration within existing transmitters such as a Power Measurement Unit (measuring in real-time the forward and reflected power levels), the TX power ON/OFF control system and the Automatic Gain Control (AGC) mechanism.

OPEX reduction thanks to better efficiency

Vortex II features the latest state-of-the-art Digital Adaptive Pre-correction (DAP) circuits achieving unequalled performances thanks to GAP© (Green Adaptive Processing) option targeting Green Transmitting.
In that way, very high level of MER and shoulders can be reached, allowing High Efficiency and Green Transmitting!
