Adjusting the TVG (Time Variable Gain) setting

You can adjust the Time Variable Gain for each sonar application in the

TVG Setup

dialog

box.

Context

The

TVG

(Time Variable Gain) function is used to compensate the received echo data for the

loss of acoustic energy due to geometric spread and absorption.

Tip

Click the

TVG

button on the top bar to enable the TVG Correction filter. This filter reduces

TVG-amplified noise at further ranges where no targets appear. You can adjust the
percentage of this filter (applied to the range) in the

Display Widget

Procedure

Select the sonar application you wish to configure from the

Sonar applications list

on the top bar.

Note

Each sonar application has its own TVG profile.

Click the

Preferences

button.

This button is located on the top bar.

Observe that the

Preferences

dialog box opens.

Click the

Show TVG Config

button.

Observe that the

TVG Setup

dialog box opens.

Drag the sliders to adjust the A, B, C, and L Factors.

Click the arrow buttons to make small adjustments.

Click

Apply

to save the settings.

Tip

Run the Sonar Head and open the

TVG Setup

dialog box if you want to see a graphical

representation of the receive signal and ensure the signal is not being clipped.
