Line Mode
The Line Mode control selects between displaying a Colour Chart based on a single line (picked
out by the crosshair cursor) or multiple lines. The Button Bar option switches between these two
settings. Where
Single line is selected, the line being analysed is shown in the bottom left-hand
corner of the display. (For details of the lines selected, see Section E.2 ‘Focus of Analysis’.)
Luma Mask
When Luma Mask is selected, the display becomes limited to those pixels whose luma value
lies between the associated Minimum and Maximum settings. The Luma Mask option on the
Button Bar toggles this selection.
Dither Mode
This option offers a choice of Dither Mode between 8bit, 10bit and 12bit.
Visualisation
The Gain control adjusts the intensity of the displayed waveform (as a percentage of the
received signal level).
The Persistence setting sets the rate at which the displayed data decays. Larger values have the
effect of smoothing out time variations.
The Gamma option allows the application (or removal) of gamma correction. ( Note: A gamma
correction of γ is removed by setting the Gamma option to 100/ γ.)
The Colour setting selects the required combination of trace and background colours as follows.
The Button Bar option cycles through the possible settings.

other standard markings.

of RGB primaries (selected on a drop-down line of the display from a drop-down list of options).

Show User option on the Button Bar toggles this selection.
The Show Source Primaries tick selection overlays a triangle corresponding to the source video
standard (identified automatically for YCbCr sources, otherwise taken from the Configuration

Show Source option on the Button Bar toggles
this selection.
The Show Labels option controls the display of labels and other additional information.
