Output Bits
Press this softkey to set the bit resolution for the serial digital outputs.
If the original Output module is installed (8100s only), there is one
control for the combined
Main
outputs (Program 1, Program 2, Preview,
Aux 1, and Aux 2) and a separate control for the
Aux 3/4
output pair, if
present. If the Enhanced (Frame Delay) Output module is installed
(some 8100s and all 8150s), there is a control for the
PGM/PVW
outputs
and separate controls for the
Aux 1/2
output pair and
Aux 3/4
output
pair, if installed. Use the
10
setting for full 10-bit resolution; this is the
default.
8 Rounded
rounds the 10-bit signal’s two least significant bits
(LSBs) up or down to the nearest true 8-bit level. Use this setting if the
output feeds an 8-bit device; the rounding reduces banding in shallow
ramps and color washes. The
8 Truncated
setting discards the two LSBs
of the 10-bit signal; use this mode for troubleshooting only.
H Blanking
This softkey appears only with the Enhanced (Frame Delay) Output
module installed (some 8100s and all 8150s). Press
H Blanking
to adjust
the horizontal blanking width of the main outputs (Program 1/2,
Preview, and Aux 1/2) and the Aux 3/4 output pair. If
H Blanking
is
OFF
, the full digital active line is output. However, the risetimes of the
blanking-to-active video transitions are unfiltered and may be subject to
ringing. Typically, you may wish to leave
H Blanking ON
to properly
filter these transitions.
The pushknobs are as follows:
Main Left –
Adjusts the blanking width of the left edge (blanking back
porch) of the main outputs, described above, in 2 pixel (148 nsecond)
steps. The range is about 600 nseconds. The default,
1
, sets minimum
blanking;
4
sets maximum blanking.
Main Right –
Adjusts the blanking width of the right edge (blanking
front porch) of the main outputs, described above, in 2 pixel (148
nsecond) steps. The range is about 600 nseconds. The default,
1
, sets
minimum blanking;
4
sets maximum blanking.
Aux 3/4 Left
– Appears only if the Aux 3/4 option is installed. Adjusts
the blanking width of the left edge (blanking back porch) of the Aux
3 and 4 outputs in 2 pixel (148 nsecond) steps. The range is about 600
nseconds. The default,
1
, sets minimum blanking;
4
sets maximum
blanking.
Aux 3/4 Right
– Appears only if the Aux 3/4 option is installed.
Adjusts the blanking width of the right edge (blanking front porch)
of the Aux 3 and 4 outputs in 2 pixel (148 nsecond) steps. The range
is about 600 nseconds. The default,
1
, sets minimum blanking;
4
sets
maximum blanking.
