Markers in the Spectrogram
Markers and delta markers are shaped like diamonds in the spectrogram. They are
only displayed in the spectrogram if the marker position is inside the visible area of the
spectrogram. If more than two markers are active, the marker values are displayed in a
separate marker table.
In the spectrum result display, the markers and their frequency and level values (1) are
displayed as usual. Additionally, the frame number is displayed to indicate the position
of the marker in time (2).
In the spectrogram result display, you can activate up to 16 markers or delta markers
at the same time. Each marker can be assigned to a different frame. Therefore, in
addition to the frequency you also define the frame number when activating a new
marker. If no frame number is specified, the marker is positioned on the currently
selected frame. All markers are visible that are positioned on a visible frame. Special
search functions are provided for spectrogram markers.
In the spectrum result display, only the markers positioned on the currently selected
frame are visible. In "Continuous Sweep" mode, this means that only markers posi-
tioned on frame 0 are visible. To view markers that are positioned on a frame other
than frame 0 in the spectrum result display, you must stop the measurement and select
the corresponding frame.
