T-TAP Pro Thunderbolt 3 to 12G-SDI/HDMI v16.1 19 www.aja.com
Control Screen
The T-TAP Pro can be controlled by various software applications running on a
host computer. The Control Screen is where you select how the T-TAP Pro directs
video and is used by application software. At the right-top of the block diagram it
will show the current Default Output and the application currently controlling the
T-TAP Pro.
Default State
This is where you select what T-TAP Pro will output as a default when no
application has control of the board, such as when the Finder is active. Since
T-TAP Pro can be controlled by multiple software applications and its own
control panel, the output can change dynamically. When you select many video
applications, they will grab control of the T-TAP Pro outputs. These settings
determine what happens when an application that doesn't grab the T-TAP Pro
outputs is active.
Test Pattern
With Test Pattern selected above, you can choose the pattern type. Select from:
• Black, Color bars (75% or 100%), Ramp, Multiburst, Line Sweep, Multi Pattern,
or Flat Field, Check Field, White, Border, Linear Ramp, Slant Ramp, Zone Plate,
Color Quadrant, Color Quad Border, or 2SI Alignment (see below).
2SI Alignment -
This test pattern consists of 1-pixel diagonal crosshairs plus a
3-pixel rectangle. If there is a misalignment, the diagonal crosshairs will not
be a continuous line. If it is a top-bottom misalignment, the top and bottom
of the square line will be broken, with white between them. If it is a left-right
misalignment, the left and right lines of the square will be fuzzy or broken.
This can easily be simulated by clicking the "Quad Swap" buttons in the
control panel "Video Setup" tab.
For HD and UltraHD with RGB-12 Pixel Formats the following HDR test patterns
are available:
• HDR Zone Plate, HDR Linear Ramp, HDR HLG Narrow, HDR PQ Narrow, or HDR
PQ Wide.
