Display Information
Waveform Pop-Up Menu
and Settings
The Waveform po
p-up menu enables you to choose the display style and display
mode used in the active tile (SDI inputs only), to select a filter to apply to the
input signal, to turn on the Multi-Input display mode, and to center the waveform
in the display.
To choose a display mode, select from the following the choices (only available
while displaying SDI inputs) in the menu:
YPbPr - Displays the input as Luma (Y) and color difference (Pb, Pr)
components.
YRGB - Displays the input as Luma (Y), Red (R), Gree n (G), and Blue (B)
components.
RGB - Displays the input as Red (R), Green (G), and Blue (B) components.
SDI > Composite - D isplays the SDI input as if it is encoded into composite.
The sync and burst in this mode are synthetic and convey no information
about signal quality.
When viewing 525-line SDI input as a composite waveform while using line select
mode, both burst phases may appear when you would expect to see only one. This
is because the line selection in SDI Mode is an odd/even selection, and composite
signals are normally viewed with a one-of-four or one-of-eight line selection.
To choose how the signal components are displayed in the active tile, u se the
Display Style menu setting (SDI inputs only) to select:
Parade style - has all the components shown one beside the other.
Overlay style - has all the components drawn at the same location so that
they appear one on top of the other.
The Waveform p op-up menu Filter selection a llows you to select filters to be
applied to the video. This is useful for isolating a specific characteristic of the
input. For example, to m easure amplitude, you may want to use a Luma or Low
p
ass filter to remove the high frequency components.
To choose a filter select one of the following filters from the Waveform menu:
Flat - Display with the full available bandwidth.
Luma or Low Pass - Display only the low-frequency part of the signal.
Chroma - Display only the part of the signal with frequencies near the color
sub-carrier. For Composite inputs only.
Flat + Luma - A combination of a Flat and a Luma waveform from a
Composite input; it shows two waveforms in parade configuration.
NOTE. For SDI displays, such as RGB mode, the available filters are Flat and
Low Pass. For Composite displays, the available filters are Flat, Luma, Chroma,
and Flat+Luma.
