High-end DTMB/DVB-T2 Digital Modulator, Model:Tornado
The TORNADO product is a state-of-the-art DTMB digital modulator bringing highest performances and maximum standard usage flexibility. It has been especially designed to meet Chinese Transmitter manufacturers’ demand for using a high-end digital modulator with top class of RF signal performances thanks to the Digital Adaptive Pre-correction circuits, providing a high MER value, excellent shoulder levels and lowest phase noise (compliant with SARFT requirements).

Green Adaptive Processing (GAP):

Today, Broadcasters become more and more concerned about operating costs reduction, including energy usage cost saving.
In this context, Transmitter Manufacturers challenge consist in designing transmitters with efficiency as higher as possible. In such design, the modulator is playing a key role especially regarding the Digital Pre-correction mechanism. TeamCast is offering new algorithms called Green Adaptive Processing (GAP) that permits to run transmitters very closed to their saturation limit, with unequalled RF signal performances and allowing significant gain in transmitter power efficiency.

World-wide leading and proven DVB-T2 technology:
DVB-T2 transmission is supported as a software option on TORNADO. This would authorize DTMB transmitter manufacturers to rapidly launch their own product for DVB-T2 addressing a world-wide and a constantly growth market. TORNADO inherits from the world-wide leading DVB-T2 technology designed by TeamCast and already in use in main of the commercial DVB-T2 networks today in operation. In particular, this DVB-T2 modulation core bring unmatched standard compliant features such as System A and System B transmission schemes for both MFN and SFN operating modes, SISO/MISO, Multi-PLP layered modulation and hybrid T2-Base & T2-Lite simultaneous transmission.
