Sv(f) page

The information is provided as a plot that shows the how the echo strength for a group of targets (for example a school of fish) change with the operational frequency. This functionality allows you to identify the nature of the schools, and discriminate between them. The Sv(f) page controls the properties used to create the Sv(f) information pane.
