10 Creating a Sv(f) information pane with echo data from multiple channels
The Sv(f) information pane shows you the volume backscatter as a function of the frequency. 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. In order to collect information from more than one channel in the Sv(f) information pane, you can use the Combined View Settings functionality to "combine" echo data from several channels.
Prerequisites
The dialog box can only be opened if you have more than one channel in your EK80 presentation. In this context, the term channel is used as a common term to identify the combination of transceiver, transducer and operating frequency.
Context
The Combined View Settings dialog box lists all your current channels. When activated, a dedicated view is created to hold the information pane and one echogram.
