4.4.4.3. Setting the Phase of the Analog Video Test Generator
The Analog test signal output can be adjusted independent of the Sync and SDI test generator outputs.
There are four menu items that are used to set the phase of the Analog Test Generator output. Refer to
Figure 4-7 and Figure 4-8 to see the default alignment for 59.94Hz and 50Hz systems respectively.
The left LCD display will show
Live control
in green to indicate that adjusting
the Analog Video Test Generator output phase menu items will affect the phasing
of the Analog Video Test Generator output immediately. You do not have to press
the SELECT button to accept the new values. Use these controls with caution.
OUTPUT
There are four menu items that are used to adjust the phase of the analog
test generator output. 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. Rotate the
control knob or press the
and
buttons to change the phase value.
Note
: 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 incremented 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. For example, when the fine phase is adjusted past 99.6%, it will
wrap to 0.0% and the horizontal phase will automatically be incremented
by one.
Caution
: These menu items are live controls. Changing their values will
immediately affect the analog video test generator output.
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 output in steps of whole frames. It is normally used to align the
color frame sequence.
Select
Vert phase
to adjust the phase of the output in steps of lines.
Select
Hor phase
to adjust the phase of the output in steps of samples.
Select
Fine phase
to adjust the phase of the sync output in fractions of a
sample. 100.0% is equivalent to one sample period.
