T05 SERIES - HEADEND EQUIPMENT
The MDU solution Satellite Channels into your CATV Network This transmodulator transforms the information from a satellite transponder (QPSK modulation) to a VHF or UHF channel (QAM modulation). The selection of the input and output signal parameters is carried out by means of a portable programming unit.
