processor is ready to receive data from the PS programmer. When the
channel processor has been programmed, programming mode should be
deactivated by placing the switch in the OFF position. The programming

FREQUENCY PLAN

6.1 Digital channels
To work with digital channels, we select Mode:
programmer. When the selection has been made, the processor can be
programmed by channel or by frequency, either input or output. If we
choose to program by Frequency, the central frequency of the channel
can be entered directly. Alternatively, it can be selected by adjusting the
frequency in steps of ±1 MHz. If we choose to program by channel,
standard channels can be chosen when the words Output channel
B/G CCIR C appear on the screen of the PS programmer. If we know that
the centre broadcasting the signal is transmitting the channel with a
particular offset, we can adjust the processor with an input offset (Input
offset) and an output offset (Output offset) equal to or different
from the one received, in steps of 166KHz.
