Simrad SP90

How to adjust the gain

You can adjust the sonar gain by means of the control buttons
on the Sonar Control Panel, or by using the

Gain

button on the

Horizontal

and

Vertical

menus.

Using the Sonar Control Panel:

1

Locate the

Gain

field on the Sonar Control Panel.

2

Press the

Gain H+

or

Gain H-

to increase or decrease the

horizontal gain.

3

Press the

Gain V+

or

Gain V-

to increase or decrease the

vertical gain.

Using the menu system:

1

Click the

Horizontal

or

Vertical

tab to open the respective

menu.

2

Click the

Gain

button to adjust the gain.

• Click the left side of the button to decrease the gain.

• Click the right side of the button to increase the gain.

• Click the middle of the button to open the parameter

dialogue.

How to control the AGC

The

AGC

(Automatic Gain Control) adjusts the gain in the

sonar’s preamplifier circuitry. This gain depends on the strength
of the incoming echo signal. The result is a filter effect, reducing
noise and reverberation. The

AGC

has four different settings.

1

Click the

Horizontal

or

Vertical

tab to open the respective

menu.

2

Click the

AGC

button to adjust the parameter.

• Click the left side of the button to decrease the parameter

value.

• Click the right side of the button to increase the

parameter value.

• Click the middle of the button to open the parameter

dialogue.

How to control the RCG

The

RCG

(Reverberation Controlled Gain) regulates the receiver

gain individually for each of the receiving beams. If you select

Weak

and

Medium

, echoes from propellers, surface and bottom

reverberations will be suppressed, while target echoes will
remain in view. If you select

Strong

, a special filter removes the

bottom, while echoes on the bottom will be presented.
