Narrow, Medium, Wide and Automatic. The actual bandwidth frequencies depend on the
telemetry frequency. If the Automatic option is selected, then the system selects the optimal
bandwidth depending on the current value of the pulse length. Note that the narrower the
bandwidth, the less signal is fed through which results in a less noisy image. By the same
token, image strength is reduced at narrower bandwidths.
Transducer
option is only available for heads equipped with remote switch able Fan-Cone
transducer. It changes the active beam shape between a conical (symmetrical) and Fan
(Asymmetrical in orthogonal direction).
The
Transmitter
control is used to select the transmitter source for heads that are equipped
with a remote control transmitter switch. In the case of an altimeter (1007 Echo sounder), the
Options are
Off
(listen only),
On
, or
Test
(calibrated test tone for factory testing). For the new
1071 based analog sonar heads, the Test tone is automatically selected if the transmitter is
turned off in low Power mode. For normal operation of the sonar head, the transmitter should
always be left On.
Power
controls the current transmit power output.
The
Panel Gain
control is used to adjust the overall gain for the image from this head.
The
Range
control is used to set the display range.
The
Hardware Head Sync
control is not used with the SL35.
The
Acquisition Resolution
control is used to change the number of samples collected from
the sonar head to twice its normal value. The data is acquired and recorded in high resolution
but not necessarily displayed in high resolution. To display the data in high resolution, the
display resolution
must be set to High on the image control bar (see the Control Panel).
Note that the screen resolution must be able to support a minimum of 960x960 pixels,
otherwise the system automatically displays the sonar data in low resolution, even if collected
in high acquisition resolution.
