OUTPUT
There are four menu items that are used to adjust the phase of the sync
output. Only the black burst (NTSC-M and PAL-B) and HD tri-
level output
modes can be pha
sed. The pulse and subcarrier sync formats will always
remain in phase with the frequency reference. The wordclock phase is
controlled in the AES Audio menu (see section 0).
When any of the four phase adjustments is selected, the right LCD panel
will display a phase control screen that can be used to view all four
adjustments simultaneously. The active adjustment will be highlighted and
the other adjustments will be shown in dark text. For HD tri-level and Slo-
PAL bi-
level sync modes the color frame adjustment will not be shown. Turn
the control knob or press the  and  buttons to adjust the phase value.
Tip: Pressing in the control knob while turning will make adjustments in
steps of 16 allowing large adjustments to be done quickly.
The phase adjustments are wrapping. This means that when the smaller
phase control is adjusted beyond its maximum, it will wrap back to 0 and the
next larger phase control will automatically be i
ncremented by one.
Similarly, when the smaller phase control is adjusted below 0, it will wrap to
its maximum value and the next larger phase control will be decremented by
one.
This can be used to make very gradual phase adjustments by
continually adjusti
ng the fine phase control until the horizontal and vertical
phases reach their desired values (may take a long time).
Caution
: These menu items are live controls. Changing their values will
immediately affect the sync output and all downstream devices.
Note: Increasing a phase value () delays
the respective output.
Decreasing a phase value () advances the respective output.
The Color phase
menu item is the largest phase control that is used to
adjust the sync output in steps of whole frames. It is normally used to align
the color frame sequence for the black burst outputs. It is only available for
the NTSC-M and PAL-B sync modes and will be
disabled (shown in dark
text) for HD tri-level and Slo-PAL bi-level modes.
The Vert phase
menu item is used to adjust the phase of the sync output in
steps of lines.
The Hor phase menu item is used to adjust the phase of the sync output in
steps of samples.
The Fine phase menu item is used to adjust the phase of the sync output in
fractions of a sample. 100.0% is equivalent to one sample period.

IMPORTANT NOTICE: When the phase of a black burst sync output has been
changed, a JAM of the VITC must be performed in order to ensure proper video
to timecode alignment.
