DUAL A/D CHANNEL PROCESSOR
16
In the case of converter mode operation, use
buttons and to choose how to select the
input and output frequencies for:
• frequency mode, or
• channel mode.
In channel mode (Tables of Channels) there are the
following choices:
- EIA
- Broadcast
- EIA (IRC)
- EIA (HRC)
c. Configuration Menu 3
The next parameter is the
Slope
. Choices are 0, 1,
2, 3 and 4.
The slope balances the signal within the channel.
When the signal is analog, it changes the level
difference between video carrier and audio carrier.
d. Configuration Menu 4
ACONFIG ))
In: 125MHz
Out: 125MHz
Mode:Digital
This menu allows to choose between
analog or
digital signals
, for both input and output ports.
• Digital signals
There are three possible choices for frequency
steps: 25, 125 and 166.66 KHz.
• Analog signals
The frequency step is 250 KHz only.
In any of the extended menus 1, 2 and 3, the first
press on button (short press) allows accessing to
the selection of module A or B within the processor,
by highlighting one of the two letters. Then use
buttons and to select one of both modules.
The next press on button (short press) makes
flash the name of the parameter to be modified.
Then use buttons
and to change its value.
e. Configuration Menu 5
Each time you save a new configuration, processor
adjusts automatically the SAT stage, both gain
and frequency, to get the best possible quality
parameters of the output signal.
This menu allows you to modify slightly the
automatic adjustment made by processor to
optimize the characteristics of a specific input
signal, if necessary.
The first parameter of this menu adjusts the
SAT
frequency of the processor.
The possible values are –4, -3, -2, -1, AUTO, +1, +2,
+3, +4.
Positive values force the processor to increase
slightly the central frequency of internal filters; a
higher value means a higher increase.
On the contrary, negative values decrease this
frequency.
The second parameter of this menu adjusts the
SAT gain
of the processor.
The possible values are AUTO, +1, +2, +3.
Positive values force the processor to increase
slightly the SAT gain; a higher value means a higher
increase.
The third and last parameter in this menu sets
the degree of selectivity in the adjustment of SAT
internal filters.
