User manual
The STEREO QPSK-PAL CI transmodulator
turns a TV or radio channel (chosen by the
user) from the existing channels in a satellite
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
the subsequent modulation (according to
the standard) of the audio and video signals
of the selected program in any channel or
frequency between 46 and 862 MHz.

The module allows the access to scrambled
services by means of the use of a conditio-
nal access module.
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
PC as explained in section 6.

STEREO QPSK-PAL CI
The QPSK-PAL CI 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 17V), 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.
It is also provided with a CI connector for
the insertion of the conditional access
module (C.A.M.).
