Noise Filter
The
Noise Filter
removes unwanted acoustic noise from the SX90 presentation. It reduces
the interference from other acoustic systems (sonars and echo sounders), as well as the
noise from the propellers.
•
Horizontal Scroll
The
Horizontal Scroll
function controls how fast the echo presentation shall move from
right towards left in the Echogram view. The "speed" is controlled by adjusting the
number of pixels used to present each ping. A higher speed reduces the resolution.
