DVB 310 S, Digital Satellite Receiver for headends, DVB-S input, PAL output
DVB 310 S module is used for the reception of free channels and DVB 310 S CI module is used for free channels as well as for codified channels. In both cases, the received channels must follow the DVB-S rule. Each module allows the reception in QPSK, and the following modulation in PAL/SECAM of a TV or Radio channel. Main feature of this equipment is its modulator in Vestigial Side Band (or VSB). This modulation can be used to distribute adjacent channels in one distribution without any intermodulation problem.
