Things to Remember When Using the Timing Display
The Timing Display measures the elapsed time between the vertical syncs of two inputs. The elapsed
time is expressed in units of microseconds and lines of the selected input video, not of the
reference.
When referencing a standard definition video input to an 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 definition video lines,
which are shorter than the standard definition video lines represented by the timing display.
When referencing a high definition video input to an 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 standard definition video lines,
which are longer than the high definition video lines represented by the timing display.
The information of the Timing Display should not be used when captured SDI freeze data is
displayed.
Timing Setup Menu
To access the Timing Setup menu, press and hold the TIME function button. For more information on
the global Timing Setup menu, see Timing Setup Menu (on page 120).
Option Display Selections
The Option display shows a waveform display of the LTC or external reference inputs.
Only one option display can be shown at a time.
OPT can only be displayed when in full screen display mode.
To select the external reference or LTC waveform display, press and release the OPT button.
To access the Option Setup menu, press and hold the OPT function button.
To clear the Option Setup menu, press the SETUP or the EXIT button.
Moving the Waveform
To move the Waveform display relative to the graticule, select the POS button, and then use the
Left/Right arrow knob (for horizontal movement) and the Up/Down knob (for vertical movement).
To move the waveform in a particular direction, scroll the Left/Right (horizontal direction) or Up/Down
(vertical direction) arrow knob.
