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 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 analogue timing reference present the delay through the board depends on this
adjustment and the relative timing of the serial input and the 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.
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.
