TLKNET-6420 DVB-T2 modulator is our new product developed complying with the DVB-T2 standard.
With its advanced modulating technology, this modulator can effectively make use of the ground spectrum resources and make it possible toprovide reliable signals for fixed, mobile and portable devices.
Compared with DVB-T, the channel capacity is increased by 30% under the similar carrier to noise ratio (CNR) threshold.
It has been designed to provide a cost effective and high quality solution for broadcast network operators, system integrators and transmitter manufacturers aiming to deploy digital TV services over DVB-T2 networks in MFN environments.
TLKNET-6420 single Physical Layer Pipes (PLPs), MFN operation, and SISO/MISO transmission through its ASI and IP port.
Moreover, this device can be upgraded and controlled through network system, which allows it to be widely used in setting up digital broadcasting network and provide good signals for scientific laboratory and DVB-T2 STB.
