TVG Setup dialog box
When an acoustic pulse is sent through the water, it will gradually lose its energy. The
greater the distance between the transducer and the target(s), the greater the loss of energy.
TVG
(Time Variable Gain) compensates for the loss of acoustic energy due to geometric
spread and absorption.
How to open
Note
Each sonar application has its own TVG profile. Before changing the TVG settings, start the
sonar (click
Setup
→
Connect
), then select the sonar application you want to configure from
the
Sonar applications list
. The TVG profiles will not be saved when closing the software —
default values will apply when starting up the M3 Sonar FLS software.
Click the
TVG
button. This button is located on the tool bar.
