Page 12: System Description
M3 Sonar FLS Reference Manual System description The M3 Sonar FLS is a high-resolution, multibeam forward-looking sonar. Multibeam sonars have an array of transducers that simultaneously transmits pings (sound pulses) at a specified frequency to cover a large area in less time than a single-beam transducer.

Page 27 Getting started Context This procedure explains how to measure the available bandwidth on a 100Base-TX (100 Mbps) Ethernet link. The same procedure can be used for a 10BaseT link by selecting the appropriate sonar application and adjusting the Ethernet adapter settings to the corresponding link speed.
Page 28 M3 Sonar FLS Reference Manual Allow the system to run for a few minutes to plot the Throughput graph. Observe the graph to determine the average network link speed. An average link speed of at least 80 Mbps is required by most sonar applications (some applications and range scales will use less).
Page 29: Testing 1Pps Time Sync Mode
Getting started If you see missing pings, try reduce the value in the Override Network Link Speed box to improve the performance. Testing 1PPS Time Sync Mode If you have an M3 Sonar FLS Sonar Head with a 1PPS connector, you can synchronize the Sonar Head clock with an external 1PPS source.

M3 Sonar FLS Reference Manual Imaging Imaging applications provide long-range detection for monitoring and navigation. Description Imaging applications use the highest pulse power. They use pulse durations to get reliable long-range detection. The trade-off is a reduction in the ping rate, partially due to the long range, and partially to maintain power consumption within reasonable limits.

Page 159: Tvg Setup Dialog Box
Functions and dialog boxes TVG Setup dialog box When an acoustic pulse is sent through the water, it will gradually lose its energy. The greater the distance between the transducer and the target(s), the greater the loss of energy. (Time Variable Gain) compensates for the loss of acoustic energy due to geometric spread and absorption.
Page 160 M3 Sonar FLS Reference Manual • Geometric spread Once transmitted, the acoustic energy will spread out to form a circular beam. The width of this beam increases with the physical distance to the target(s). • Absorption loss Depending on the salinity and temperature, the water will absorb some of the energy from the acoustic transmission.
