Displaying a Signal
Inputs
There are eight rear-panel loop-through inputs, which may
eliminate the need for an external routing switcher. The in-
puts can be displayed singly or in combination.
Without
PARADE
or
OVERLAY
selected, only one input selec-
tion can be made at a time. Each input channel button (in-
cluding
A123 / B123
) toggles between
A
and
B ,
and is
cancelled when another input button is pressed.
With
PARADE
or
OVERLAY
selected, the input channels can be
displayed in combination. Pushing an input channel button
sequences through the labeled channels, both, then off. Push-
ing another input button does not cancel the current selec-
tion, but adds to it. To return to “single input” operation,
push the
PARADE/OVERLAY
button until it is off (LED is no
longer lighted).
A123 / B123
Selecting
A123
provides a side-by-side display of the
CH-A1,
CH-A2,
and
CH-A3
inputs (
B123
displays the
CH-B1, CH-B2,
and
CH-B3
inputs). This is designed for monitoring component
signals.
Parade
Selecting
PARADE
displays the input channels last selected
for
PARADE
,
allowing a custom configuration of inputs. In
PARADE
mode, the
LINE/FIELD
button offers only two choices:
one line and one field.
PARADE
allows up to four channels to be displayed side-by-
side. Additional channels will be overlaid.
