1 DESCRIPTION
With the option Composite IF AUX input it is possible to switch to an alternate CIF source. This
source can be an IF backup or IF channel.
The input is ALC (automatic level controlled) referred to the vision carrier. The input level ranges
b30 dBmV and +45 dBmV. (default = + 40 dBmV) Within that range a constant RF output is
maintained.
Manual gain control remains available by the front panel: e.g. scrambled signals.
External CompIF is only available if the Aux input is selected.
Together with the Audio/Video Auxiliary input and or the Audio SubCarrier
input, different combinations are possible. More information can be found in
the description of these options.
