Adjusting horizontal and vertical timing
The horizontal position slider adjusts output timing relative to the active analogue
reference in steps of 37ns. The range of adjustment is one video line.
The vertical position slider adjusts the output timing relative to the active analogue
reference in steps of one video line. The range of adjustment is one video frame. When
the maximum adjustment is reached the slider will move to zero.
Note:
Attempts to exceed 524 on the vertical slider graticule in NTSC mode will reset the slider to
zero.
When both horizontal and vertical position settings are zero the serial output will be timed
to the active analogue reference as per ITU-R BT.601. Increasing the vertical position
setting will delay the output relative to the reference in increments of one video line.
Increasing the Horizontal position setting will increase this delay in increments of 37ns.
With an external analogue timing reference present the delay through the board depends
on this adjustment and the relative timing of the serial input and the external analogue
reference.
When both vertical position and horizontal position are set to zero the delay through the
board will be at a minimum. The minimum delay through the board is approximately 1.7
lines in 10-bit mode and 0.7 lines in 8-bit mode.
The horizontal and vertical timing adjustments are separate for 625 and 525 line operation
and the settings are automatically maintained when the unit is powered off and restored
when the unit is powered back on.
Adjusting input video timing
The horizontal delay adjustment varies the timing of the input video relative to input
syncs and blanking in 10 bit mode whichever source is the active reference.

No horizontal delay available
The horizontal delay slider adjusts the input video timing with respect to the input video
syncs in steps of 37ns. This adjustment is available in 10-bit mode only. The available
range is -128 to +127 steps (r/- 4.5 microseconds) relative to the factory default
position. The value cannot be adjusted outside this range.
