When a signal is processed, there is the potential for it to be delayed with respect to a
reference signal. The timing display is used to indicate when a video input is deviating
in time from the reference. See “Reference” on page 82 for more information on
reference selection.
The reference input indicator (REF), located in the center of the timing display,
indicates the reference-timing point for the type of signal being monitored. REF is
green when the line and µs (microseconds) cursors are all aligned. As the signal falls
out of timing alignment, the line and the µs cursors change color when it moves from
REF. When this occurs, the REF turns red. Each hash mark represents a vertical line
(top scale) and 1µs (bottom scale). Once the line or µs cursors are at the edge of the
display, arrows will appear to the right or left of the timing line.
NOTE
: The Timing Display alignment accuracy is ±280 ns.
