Marker Status Area
The Sweepless Sweep measurement mode also contains an area
referred to as the Marker Status area (below the Graph Information
bar). This area consists of the marker name (A or B), marker frequency
(in MHz), and measured signal level for the frequencies which the
markers are on. The black square around the letter A or B indicates
the active marker. The delta label (in dB) and the delta frequency (in
MHz) between the markers is also displayed. The sweep maximum-
minimum dB level (difference between the highest and lowest points
in the sweep graph) is displayed next to the marker status.
