4.4.3.5. Setting the Phase of the SDI Video Test Generator
The four SDI test signal outputs are all phased independently from each other and can be adjusted
independent of the sync and analog video test generator outputs. Refer to Figure 4-7 and Figure 4-8 for
the default video sync alignment for 59.94Hz and 50Hz systems respectively.
There are two menu items that are used to set the vertical and horizontal
phase of the SDI test generator output. When either of the phase
adjustments is selected, the right LCD panel will display a phase control
screen that can be used to view both vertic
al and horizontal settings
simultaneously. The active adjustment will be highlighted while the other
value will be shown in dark text. Turn the control knob to adjust the phase.
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 horizontal
phase control is adjusted beyond its maximum, it will wrap back to 0 and the
vertical phase control will automatically be incre
mented by one. Similarly,
when the horizontal phase control is adjusted below 0, it will wrap to its
maximum value and the vertical phase control will be decremented by one.
Caution
: These menu items are live controls. Changing their values will
immediately affect the SDI output and all downstream devices.
Note: Increasing a phase value () delays
Decreasing a phase value () advances the respective output.
Select Hor Phase to adjust the phase of the output in steps of samples.
Select Vert Phase to adjust the phase of the output in steps of lines.

4.4.3.6. Configuring the SDI Test Generator Embedded Audio
Each SDI test generator is capable of inserting up to four groups of audio onto all supported link
formats and video standards. The audio is embedded according to SMPTE ST 272 (SD) and SMPTE
ST 299-1 (HD/3G). Each audio group contains four channels of audio all of which can be configured to
various test tones at selectable levels. There are four menu items that control each group of audio for
the SDI test generators. For the sake of simplicity, only the controls for Audio Group 1 are described in
the manual.
4.4.3.6.1. Controlling Embedding of Audio Groups onto the SDI Test Generator
The Group Enable menu item is used to enable or disable embedding of
audio group 1.
Selecting on will embed group 1 with all four channels of audio. Selecting
off will not embed this group.
