Scope
The Scope view is the rightmost view and shows a oscilloscope
view of the last ping corresponding to the settings in the
Echogram view.
This view draws a range of horizontal symmetrical colour lines.
The distance from the vertical centre axis and the line colour
reflects the received echo amplitude. A black horizontal line
across the view indicates the current bottom view.
Channel:
Test presentation for passive or test mode
Passive:
Background Noise: yyy.y dBW
Receiver Amplitude: xxx.x dBW
Alongship angle: z.zz deg
Athwarthship Angle: z.zz deg
The background noise shown is the median of 20 equidistance
power samples in the total range of the current ping. The
receiver and the two angles (alongship and athwarthship) are
sampled at 100 m depth. During replay, you may find that this
depth setting is not availbale because the depth is less than 100
m. The receiver amplitude is then set to a minimum (235 dBW),
and the angles are set to zero.
