Transmodulador Digital QPSK - QAM (controllable)

Digital QPSK-QAM transmodulator (Controllable). Ref. 5023 Televes.

Perform the operation of changing the modulation input channel (either satellite or terrestrial) to another modulation receiving device can understand. In the case of digital terrestrial signals, the input channel (COFDM modulated) will be modulated PAL (an ordinary analog channel within the VHF or UHF band) for the television to present it on the screen. When it comes to distribution in CATV networks, it can be modulated in QAM so that later, through a QAM decoder, you can see on the TV screen. If satellite signals, the digital modulation input (called QPSK) can be changed, either PAL or QAM channel to a channel, as is done with digital terrestrial signals. The parameters that can be programmed are: -The ability to select the QAM modulation format. and the modulation format I / Q.
