WK-3348T is a high performance and cost-effective DVB-T modulator. It has 8 tuner inputs.
After multiplexing and modulating process, it gives 4 DVB-T non-adjacent carriers output through one RF port. To meet customers’ various requirements, this device is also equipped with data port for IP input and output over UDP and RTP. Its pluggable structure design greatly facilitates the change of modules as needed. Moreover, the four CAMs/CIs accompanied and BISS modules can descramble the input programs from 8 Tuners and IP.
WK-S3348T can be upgraded and controlled through network system, which allows it widely used in digital broadcasting network and provide good signals for scientific laboratory and DVB-T STB.
