Timing Tab Screen
Figure 15. Example of the OG-12GM Timing Tab Screen in DashBoard with
Quad 3G-SDI to Single 12G-SDI conversion using Square Division
(Quadrant) to Two Sample Interleave (2SI) pixel mapping.
The purpose of the Timing Tab Screen is to validate that all four links of a Quad
Link input signal meet the required 400ns link-to-link timing, and if not, which
link(s) are not meeting this specification.
The Timing Tab Screen measures timing differences link to link, but displays
timing values relative to SDI 1 for ease of understanding and correcting timing
issues. The Timing analyzer has a measurement range of +/- 1/2 frame.
The Pixels row indicates any horizontal offset in terms of pixels for each link,
while the Pixels Time information indicates the horizontal offset in terms of
microseconds. These two rows display the same information represented in
different terms (pixels versus microseconds). The pixel information (pixels and
pixel time) indicates offset of up to 1 line. If the offset exceeds 1 line, then the line
count is incremented.
The Total row displays each link's total offset (vertical timing plus horizontal
offset) in terms of time.
