Beam Visualization
With the various beams provided by the SN90 system, it may be difficult to
understand the concepts. How do these beams "behave" in the water? The beam
visualization feature simulates how the acoustic beams cover the seabed and the
water column.
Diagnostics
The SN90 system is a computerized sonar. There are hardly any analogue circuitry,
and the possibility of traditional troubleshooting is limited. In order to rectify
this, a built-in software application is available to offer test and maintenance
functionality. The
that checks the performance of the SN90 system.

Transceiver
The
Transceiver
the Transceiver Unit.
The purpose of the transceiver boards is to first create and transmit the
acoustic pulses. After the transmission the transceiver boards receive the
echoes from the seabed and/or the water column. These echoes are filtered,
amplified and finally converted into digital format. This transmission and
reception sequence is commonly referred to as a ping.
Transducer
Use the
Transducer
transducer elements. Any errors are then easily detected.
Noise
The operational performance of the SN90 system depends on the noise
conditions. It is essential that the noise signature is as low as possible.
