Page 29 Simrad SY50 CAUTION When the transducer is lowered, the depth of water under the vessel must be monitored closely. If the transducer hits larger objects or bottom, the transducer shaft may be bent, or - in worst case - it can be broken off. A broken transducer shaft will cause water leakage through the top of the shaft.
Page 30 Simrad SY50 Reference Manual The transducer converts the electric energy generated by the transmitter circuitry to physical vibrations. These vibrations alter the water pressure, and create an acoustic pulse that is sent into the water. The acoustic signal is transmitted as a beam. The duration of the acoustic pulse, as well as its frequency and shape, are controlled by the system software.

Page 512 Simrad SY50 Reference Manual AGC (Automatic Gain Control) function (Automatic Gain Control) function runs an automatic analysis of the echo strength. Based on this analysis the SY50 system maintains a proper dynamic range based on all the current echo values. This is done by automatically reducing the gain if you have reverberation and noise, or increasing the gain if the acoustical conditions permit it.
Page 513 Functions and dialog boxes The most practical way to use the AGC (Automatic Gain Control) is to first switch it off. Adjust the echo presentation using the normal gain functionality until you have the best possible result, then activate the AGC. The AGC works best with even background (homogenous noise conditions) and pronounced targets.

Based on this analysis the SY50 system maintains a proper dynamic range based on all the current echo values.
Page 679 Concept descriptions The most practical way to use the AGC (Automatic Gain Control) is to first switch it off. Adjust the echo presentation using the normal gain functionality until you have the best possible result, then activate the AGC. The AGC works best with even background (homogenous noise conditions) and pronounced targets.
Page 680 Simrad SY50 Reference Manual The automatic gain control (AGC) may override the effect of the TVG (Time Varied Gain). If you want to examine weak echoes that are very close to your vessel, use a low TVG setting (for example, 10 log R) or turn the TVG off.

Page 689 Concept descriptions What is sampling? The information from the transducer on the SY50 system is a continuous flow of analogue data. In signal processing, sampling is the reduction of this continuous signal to a discrete signal. A common example is exactly what we do in the SY50 system. We convert a sound wave (which is an analogue continuous-time signal) to a sequence of samples (which is a discrete-time signal).

Page 692 Simrad SY50 Reference Manual The transducer can pick up noise from: • Biological disturbances • Interference • Cavitation • Propeller noise • Flow noise • Acoustic noise from other hydroacoustic systems The transducer cable is long. Electric noise from generators, pumps, cooling systems and other electric or electromechanical devices is easily picked up.
Page 693 Concept descriptions • Water-borne noise through the hull into the water to the transducer. Electrical noise Modern vessels are normally equipped with a lot of electric instruments such as hydroacoustic systems, radars, navigation systems, and communication equipment. Any electric instruments may in some cases cause electrical interference and noise. International regulations and certifications are used to control and reduce this, but even these are limited if the electrical systems are poorly installed and/or maintained.
Page 694 Simrad SY50 Reference Manual will generate friction. The friction zone is called the flow boundary layer. The water flow in this boundary layer may be laminar or turbulent. • The laminar flow is a nicely ordered, parallel movement of the water.
Page 695 Concept descriptions usually refers to the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves or matter waves.
Page 696 Simrad SY50 Reference Manual The most common source of electrical self-noise is hum. Hum is typically generated by low-quality power supplies. Transducer cables and sensitive electronic circuitry can easily pick up hum. At higher frequencies – where rather wide bandwidths are necessary – the noise from components, transistors or other analogue electronic may be a limiting factor.
Page 697 Concept descriptions The illustration demonstrates how the sea bottom and the sea surface return echoes back to your sonar system. (CDCD010202_301_001) In this situation you will be able to identify the upper school of fish, but the lower school will be hidden in the shadow of the seabed rock formation. In this situation you will see several weak echoes from the waves and from the rock on the bottom, but you will still be able to identify the school of fish.
Page 698 Simrad SY50 Reference Manual Note The information here must be considered as general advice. Each system installation must be handled separately depending on the hull design and the other electrical and mechanical systems installed on the vessel. Reducing flow noise The shape of the hull plating around the installation trunk opening must be as streamlined as possible.
Page 699 Concept descriptions Reducing rattle noise Ensure that no parts near the transducers can rattle as a result of water flow or vibrations. Reducing interference Interference from the transmission pulses from other hydroacoustic instruments on board the vessel is difficult to avoid. The problem may be reduced by choosing the working frequencies carefully and to some extent by separating the different transducers.
