Timing Analyzer
The Sync/Timing menu on Karrera systems (accessed via Eng Setup , Video
Settings ) has a Timing Analyzer pane ( Figure 39 ), which can help when
timing the system.
Figure 39. Video Settings Menu,
This analyzer reports the timing position of a selected source relative to the
Karrera internal sync generator. The source is selected with the upper right
Analyzer Source soft knob and data pad. The relative position of that source is
reported in lines and μs. Positive values indicate the source is later in time
than the internal sync generator, and negative values indicate the source is
earlier.
Karrera systems have an autotiming window. Sources that fall within that
window will be properly timed throughout the Karrera system, even if the
signal is cascaded through multiple MEs.
The Switcher Horizontal and Switcher Vertical soft knobs adjust the timing of the
Karrera system relative to the incoming reference. These values are gener-
ally best left at zero.
