STM-3500B DVB T2 modulator complies with the DVB-T/T2 standard. With its advanced modulating technology, this digital rf modullador can effectively make use of the ground spectrum resources and make it possible to provide reliable signals for fixed, mobile, and portable devices. Compared with DVB-T, the channel capacity is increased by 30% under a similar carrier-to-noise ratio (CNR) threshold.
Moreover, the DVB T2 modulator can be upgraded and controlled through a network system, which allows it to be widely used in setting up digital broadcasting networks and provide good signals for scientific laboratories and DVB-T/T2 STB.

Among several major digital TV terrestrial transmission standards (DVB-T, ISDB-T, DTMB, DVB-T2), DVB-T2 is the latest to appear, and it is also a master of various latest technologies. The highest TS stream transmission rate supported by DVB-T2 in the 8 MHz bandwidth is about 50.1 Mbit/s, and it will be even higher if its empty packet deletion mechanism is counted. This is obviously much higher than the highest transmission rate of 31.67 Mbit/s of DVB-T, 32.4864Mbit/s of DTMB, and 23.234Mbit/s (6M bandwidth) of ISDB-T.
The following table reports a comparison of available modes in DVB-T and DVB-T2:
