Twin processor

Frequency shifting for any modulation

The module processes 2 input channels, either analogue or digital, irrespective of the service type, to work either as a channel converter (using different input and output channels) or as an amplifier (using the same input and output channel).

Highlights
  • SAW (Surface Acoustic Wave) filtering. Provides a high selectivity, avoiding adjacent channel interference.
  • Adjustable slope to balance signal inside the bandwidth.
  • Can be remotely controlled using CDC (Headend control)

Main features
  • In converter mode, it allows the assignment of an output channel different from the input channel (Twin).
  • In amplifier mode, it allows the equalization and filtering of a Digital Multiplex to adapt it to the levels of the other signals.
