Display Information
40
To choose the display type (SDI inputs only), use the pop-up menu to choose:
Vector – The Vector display shows a plot of the R-Y signal on the vertical axis
and the B-Y signal on the horizontal axis. This display is useful for looking at
hue and amplitude of the colors, but does not show luminance information.
Luma Qualified Vector – The Luma Qualified Vector display (available with
Option PROD) is a vector display that is gated by a specified luminance range.
Each vector tile may have a different luminance range specified.
Lightning – This Tek proprietary display shows the same color signals as in
the Vector mode, but they are plotted against luminance. One color difference
signal is plotted in the top half and the other in the bottom. The Lightning
display is useful for checking chroma and luma gain, and for checking chroma
to luma delay using the timing marks that show errors in the green to magenta
transition on a color bar signal.
To select which scaling should be used in the active tile for either the Vector or
Lighting display, use the menu to select 75% or 100% scaling.
To turn on the Multi-Input display mode, select Multi-Input Display and press
SEL. Next, press and hold the Display Select button to view the display full-tile
and activate the Multi-Input view.
NOTE.
The Multi-Input menu option is only available in the VECTOR pop-up
menu when the feature is enabled from the MAIN button or CONFIG button menu.
(See page 26, Multi-Input Display Mode.)
NOTE.
The 3D display menu options are only available in the VECTOR pop-up
menu when the feature is enabled from the MAIN button menu. (See page 30,
3D Input Monitoring.)
To cancel any horizontal or vertical position adjustments and restore the trace to
the default position, use the up/down arrow keys to select Center Waveform
in the menu.
For a Lightning display, press SEL to center the waveform. The trace is set
back to the center of the tile.
For a Vector display, press the right-arrow key to select the color you want
to locate at the center of the display.
For additional vector graticule options, see the CONFIG > Graticules and
Readouts menu and select I/Q axis or Compass Rose.
