Field Information
Nomenclature
Horizontal can be yellow at 0 µs. It displays the minimum scale
resolution at 1 µs and the minimum timing resolution at 0.037 µs
for HD (High Definition) and 0.74 µs for SD (Standard Definition).
5
Input
Displays selected input (A or B)
6
Standard
Displays the line rate/frame rate; select the Standard in the Video
Setup menu
7
REF OFFSET
Displays that the zero point of the timing measurements are offset
from the REF selection by xx lines yy.yyy µs

Timing Graticule
Shows the timing graticules, cursors, and labels
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
Timing Setup Menu (on page 120) 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 1 µs (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.
The Timing Display alignment accuracy is ±280 ns.
