Echogram page
The echo presentations in the Inspection views resemble the echograms you see on an
echo sounder. The
Echogram
page allows you to choose which type of echogram you wish
to display. You can also control the TVG (Time Variable Gain). The ST90 system can
work with several different TVG compensation settings. The TVG (Time Variable Gain)
compensation is designed to counteract the natural phenomena of geometric spread and
absorption loss.
How to open
This page is located in the
Echogram

Echogram
dialog box is located on the
