The channel bar above the diagram not only displays the channel-specific set-
tings. It also displays information on instrument settings that affect the measure-
ment results even though it is not immediately apparent from the display of the
measured values. This information is displayed in gray font and only when appli-
cable for the current measurement, as opposed to the channel-specific settings
that are always displayed.
