Configuration
Primary – Secondary Phase Difference
This graphic is provided to show the total phase difference between the
Primary and Secondary reference signals. When the bar is green and
remains in the area before the horizontal indicator, the two references are in
a range where switching between the two will show no measurable distur-
bance in the output video (approximately 72 nS).
When the phase difference is larger than the recommended amount, the bar
will indicate by showing a second red bar. This indicates that the phase dif-
ference is now such that switching between the two references will show a
disturbance in the output video. This can be caused by a loss of one of the
references or a mis-adjustment in the reference output delay of either refer-
ence. The total phase error shown in this graphic represents approximately
1 uS.
If the red bar appears, check the System Config page for the presence and
lock status of both the Primary and Secondary references. If there is a
timing difference, use the Genlock web page timing controls to bring the
two references into the green bar range. Refer to the Genlock Web Page
on
page 59 .
Split Screen
Use a horizontal or vertical split screen to compare the unprocessed input
video (top or right) to the processed output video (bottom or left). This
control is duplicated and tied together with the Split Screen controls on the
Color Correction and Video Proc web pages. Changes made on any one of
the Split Screen controls will control all three screens.
• Split Enable – enable the split screen by checking the Split Enabled
checkbox.
• Orientation – select the orientation of the split screen with the Vertical or
Horizontal radio button.
• Position – use this control to set the amount of horizontal or vertical split
(10 to 90%) of unprocessed video to appear on the screen.
