The SAT-RF transmodulator turns a TV or
radio channel (selected by the user) from the
existing channels in a satellite transponder
(FM analogue modulation and an approxi-
mate bandwidth of 27 MHz) into a VHF/UHF
channel (PAL / SECAM standard modulation
and a bandwidth of 7/8 MHz).
The selection of the different parameters
(input frequency, audio subcarrier, output
level, output frequency, ...) is carried out
1.- IF input + V
2.- IF output

output channel
using the programmer ref. 7234, that is con-
nected to the front of the device.
The SAT-RF transmodulator disposes of an
IF input and output in the upper "F" connec-
tors with the aim of enabling the input signal
to pass to various modules, it also allows
the powering of a converter via the IF input
(13V or 18V), as well as being able to gene-
rate a 22 KHz tone for the selection of the
converter's oscillator by this connector.
