Pages in the Echogram dialog box
The
Echogram
dialog box allows you to control the echogram presentation in the Inspection
views. Two pages control the horizontal lines and the echogram type with applied TVG
(time variable gain). One page controls how fast the echogram travels horizontally across
the presentation.
How to open
This dialog box is opened from the
Active
menu.
Description
The ST90 system offers several inspection beams. Each inspection beam is presented using
an
Inspection view. Each Inspection view shows you echo data from a separate beam.If you
use several Inspection views, you can train and tilt the beams individually, and independent
of the beams displayed in the other views. The echo presentations in the Inspection views
resemble the echograms you see on an echo sounder. Each Inspection view can be regarded
as an "echo sounder" with an adjustable direction. In the ST90 system we use the phrase
echogram to describe the information provided by the views.
Note
The dialog box is only available when an Inspection view is active. To activate a view, click
in it. The active view is identified with a thicker border.

page in the
Echogram
dialog box allows you to control the horizontal
and vertical lines used in the echogram presentation. You can make the bottom easier to
see, and add lines that hold additional information. The vertical scale of the echogram
presentation can be changed. If you wish to add annotations to your echogram, these are
enabled on this page.
