2 photosFUQ3514B Modulator Dual DVB-ASI-SMPTE-310 Inputs
The Hanxing FUQ3514B is an RF modulator in the FUQ3 line, built in our Guangzhou headend factory. Published specifications: Output Level ATT -20dBm~6dBm,0.1dB stepping; Constellation 8VSB; Standard ATSC A/53. 14 parameters are published on this page from the model's own datasheet; quotations are factory-direct.
The FUQ-3514B (FUQ-3514F) modulator accepts dual-channel DVB-ASI and SMPTE-310 inputs and delivers RF output from 50MHz to 860MHz. ATSC 8-VSB modulation follows the ATSC A/53 standard, with adaptive digital pre-distortion (DPD) on the signal path. Control is available over IP or the front panel. Buyers use it for ATSC broadcasting networks and set-top box testing.

Next stage in the chain
A modulator creates the channel; a transmitter decides how far that channel travels. Once the channel line-up is fixed, the transmitter stage sets output power, filtering and monitoring for the coverage area, which is why both stages are specified together rather than separately.
