4. - ELEMENT DESCRIPTION

4.1.- TDT +

The transparent digital transmodulator,

referred to as the TDT+, turns the

information contained in a satellite

transponder for example (QPSK modulation)

and a maximum bandwidth of 36 MHz into a

VHF or UHF channel (QAM modulation) and

a maximum bandwidth of 8MHz (depending

on the selected QAM modulation).

The TDT+ performs the QPSK demodulation

of the input channel (transponder) obtaining

a MPEG2-TS signal (MPEG2 Transport

Stream). Then the TDT+ performs a QAM

modulation of this MPEG2 signal, which

implies a modulation change of the digital

information (digital transmodulation).

The input channel, the input signal

parameters and the output channel

paramters are selected using the

programmer ref. 7234 which is connected to

the front of the device.

It is also possible to control the unit using a

PC as explained in section 7.

The TDT+ disposes of an IF input and

output in the upper F connectors so as to

enable the input of the signal into various

TDTs +. It also allows us to power a

converter via the signal input (13/18 V). In

the case of a shortcircuit, the front LED

flashes on and off, stopping when the

shortcircuit is over and when the 13/18V

is back in the connector. It also has an

input and output RF connector, for the

channels to be mixed before they are

amplified.
