The QPSK-PAL transmodulator turns a TV
or radio channel (chosen by the user) from
the
existing
channels
in
transponder (QPSK modulation and an
approximate bandwidth of 36 MHz) into a
VHF/UHF channel (PAL modulation and a
bandwidth of 7/8 MHz).
To do this, the unit carries out the QPSK
demodulation
of
the
input
(transponder), thereby obtaining an MPEG-2
TS (MPEG-2 transport stream) to carry out
QPSK-PAL
DVB Sub
the subsequent modulation (according to
the standard) of the audio and video signals
of the selected program in any channel or
a
satellite
frequency between 46 and 862 MHz.
The selection of the different parameters
(input frequency, S.R, output level, output
frequency, ...) is carried out via the program-
mer ref. 7234, that connects to the front of
the device.

It is also possible to control the unit from a

Product reference
Indicate the program-
med output channel
The QPSK-PAL transmodulator disposes of
an IF input and output in the upper "F"
connectors with the aim of enabling the
input signal to pass to various modules and
to allow the powering of a converter via the
IF input (13V or 18V), as well as to be able to
generate a 22 KHz tone for the selection of
the converter's oscillator.
It also has an RF input and output connector
so as to be able to mix the channels for their
subsequent amplification.
