3.6 Color bars
For set up and test purposes, the XCU can generate a color bar signal at the HD-SDI output
connectors. This signal will be only present when no camera is connected and no valid video
signal is received.
• To turn on the XCU color bar, go to the VIDEO > COLOR BAR > COLOR BAR item and select
On.
• The color bar type can be selected with the VIDEO > COLOR BAR > COLOR BAR TYPE
item. Two color bar types are available: Split (default) and Full.
3.7 Timing
All main HD Video, SD and monitoring output signals coming from the XCU are in phase. Still,
due to different cable lengths or other delays, the signals from different XCUs can be out of
phase when they are connected to a video switcher or router.
This variation in phase can be compensated for in the XCU by using horizontal phase (H-phase)
adjustment. Go the INSTALL > TIMING menu and adjust the H-PHASE item.
The phase shift can be further adjusted in the INSTALL > TIMING > SHIFT menu. Use the
PIXELS and LINES items to shift the signals over one or more pixels and one or more lines,
respecively. The maximum shift is exactly one frame.
