COFDM-PAL NICAM
The amplifier carries out
amplification of the channels generated
in the COFDM-PAL transmodulators,
covering a frequency range of 47 - 862
MHz.
It disposes of two input signal connec-
tors to mix the channels coming from
two systems. If only one of the inputs is
used, it is advisable to load the unused
input with 75 ohm, Ref 4061.
The amplifier disposes of an output
connector and a Test socket (-30dB)
located at the top of the front panel.
The amplifier is powered with 15V via a
cable, the same type as that used to
power the other modules of this system.
