Gamut Window
The display in this window chiefly comprises a set of bar graphs showing the range of
values for the different possible colour components (YCbCr, RGB and Composite – or
XYZ when Dual Link mode is selected) in the video currently being analysed. The range
of colour components for which graphs are displayed is selected from the Control panel
which is displayed/hidden by clicking on a release catch similar to that on the Waveform
window (see page 55).

which is displayed/hidden by clicking on a release catch similar to that on the Waveform

The individual graphs show the ranges encompassed by the current frame. Where the
values go outside the ranges specified on the Video: Analyzer page of the Engineering
Settings control window, the values in excess are shown in a different colour. (The
colours used are set on the Waveform and Gamut page of the Look & Feel dialogue,
which is called up by taking the Look and Feel option from the Options menu – see
below.)

Options menu
The Options menu in the Gamut window includes the following options:
Graticule
The graticule lines can be displayed or hidden, along with graticule text labels. In
addition, amplitude markers may be overlaid onto the main graticules. These are
horizontal lines that can be used to mark out important levels. It is possible to define
multiple markers, and change which is displayed, or to display several at a time. It is also
possible to opt for minimal labelling on the various displays.

Note that the units for both axes of the graticules are customizable, using the global
selection on the File/Preferences menu selection. For example, this can switch between
decimal or hexadecimal values, or into a mV scale. See page 14 for details.
