scale resolution at 1µS and the minimum timing resolution at .037µS for HD (High
Definition) and 0.74µS for SD (Standard Definition).
Things to Remember When Using the Timing Display
1. The Timing Display measures the elapsed time between the vertical syncs of two
inputs. The elapsed time is expressed in units of pixels and lines of the selected
input video not of the reference.
2. When referencing a standard definition analog or digital video input to a high
definition video or external tri-level reference input, the line number indication in
the timing display represents standard definition video lines. If the relative timing
is adjusted in high definition video lines, it may take an adjustment of two or more
lines before the line number changes in the timing display. This is due to the high
frequency high definition video lines, which are shorter than the standard definition
video lines represented by the timing display.
3. When referencing a high definition video input to a standard definition analog,
digital video, or external composite (BB) reference input, the line number
indication in the timing display represents high definition video lines. If the relative
timing is adjusted in standard definition video lines, a single video line adjustment
will cause a change of two or more lines in the timing display. This is due to the
low frequency standard definition video lines, which are longer than the high
definition video lines represented by the timing display.
4. The information of the Timing Display should not be used when captured SDI
freeze data is displayed.
