HPS8502 DVB-T/T2 Modulator
Outline
HPS8502 DVB-T/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 to provide reliable signals for fixed, mobile and portable devices. Compared with DVB-T, the channel capacity is increased by 50% under the similar carrier to noise ratio (CNR) threshold. HPS8502 DVB-T2 modulator also supports single-PLP and MI (T2-MI) interface, and can receive transmission data and synchronous information from DVB-T/T2 Gateway through its ASI and IP ports.
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-T/T2 STB.
Features
Fully complying with EN302 755 and EN300 744 standard
2ASI input ports
2 IP input over UDP protocol
10MHz input/loop out, 1PPS input/loop out
DVB-T/T2 RF out in one device
Supports single PLP
Support MISO and SISO
Support MFN net mode
Supports non-linear digital pre-distortion (DPD)
Constant temperature crystal oscillator, as high as 0.1ppm stability
Support PID bypass and pass-through（option）
Keyboard operation and LCD display
