5.7 KEY SETTINGS
The following section will explain some of the key settings for the SL 35 Hull Sonar
in order to maximize the performance.
5.7.1 AGC Setting
The Automatic Gain Control “ AGC” algorithm increases the gain during the low
acoustic return and reduces the gain during strong acoustic returns. The speed with
which the gain is adjusted is determined by the setting of the “RX Gain Response”
as explained in the next paragraph.
