Processor Channel A/D Twin Televes
KSh155,978.00
Module that processes 2 input channels, analog or digital, regardless of the type of service, to function as a channel converter (using different input and output channels) or as an amplifier (with the same input and output channel). Televes 564901
Module that processes 2 input channels, analog or digital, regardless of the type of service, to function as a channel converter (using different input and output channels) or as an amplifier (with the same input and output channel).
Stands out for
SAW Filtering (Surface Acoustic Wave). It provides high selectivity, avoiding interfering adjacent channels.
Adjustable slope, to balance the signal within the bandwidth.
Remotely controllable with the CDC (Head Control)
Features
In converter mode, it allows assigning a different output channel to the input channel (Twin).
In amplifier mode, it allows to equalize and filter a Digital Multiplex to adapt it to the levels of the rest of the signals.

DVBS/S2 Transmodulator with CI – COFDM Televes
KSh249,986.00Add to cartEquipped with CI. The transmodulator receives a SAT transponder in DVBS (QPSK) or DVBS2 (QPSK /8PSK) modulation and demodulates it, producing an MPEG-2 transport packet. The MPEG2 transport packet is subsequently modulated in COFDM and converted into the output channel (UHF or VHF, with a 7/8 MHz bandwidth), using an agile up-converter. Televes 563301
