Screen Service DVB-S and DVB-c Modulators

The units in this series constitute the new generation of QPSK and QAM modulators for the transport of digital television signals.They are available in stand-alone version (1 standard 19” rack unit) and the plug-in version for Screen Service equipment with standard intermediate frequency output (70MHz) or, depending on the model, in frequencies varying from 10 to 160 MHz, supporting payloads up to 60 Mbits/s (QPSK) and 155 Mbits/s (QAM).They may be used to feed microwave links for fixed or mobile connections, for cable TV head-end systems, or for satellite up-link, conforming to EN 300 421, EN 300 429 and EN 301 201 specifications.All models are given an internal network adapter and two independent outputs so as to facilitate distribution of the modulated signal.Depending on the version, configuration parameters of the modulators are managed and visualized, either by a local control panel with relative display, through a RS-232 serial connection port or through a user interface in Java .
