COMPANY BACKGROUND EdgeTech (formerly EG&G Marine Instruments) traces its history in Underwater Data Acquisition and Processing back to 1966. EdgeTech has designed, developed, and manufactured products, instruments, and systems — for the acquisition of underwater data, including marine, estuarine, and coastal applications — for over 50 years. EdgeTech responds to the needs of the Scientific, Naval, and Offshore communities by providing industry‐ leading equipment — such as Sub‐Bottom Profilers, Side Scan Sonar, Acoustic Releases, USBL Positioning Systems, and Bathymetric Systems — that have become standards in the industry. EdgeTech consistently anticipates and responds to future needs with an active Research and Development Program. Current efforts are focused on adapting new cutting‐edge acoustic technology. 2300 COMBINED SONAR SYSTEM ...
Using EdgeTech’s proven Full Spectrum™ CHIRP technology to provide crisp, high‐resolution imagery, surveyors can choose to operate any two frequencies simultaneously from the tri‐frequency system. EdgeTech has designed the 2300 to incorporate up to four low‐frequency transducers as part of the company's DW‐106 (1‐10kHz) deep penetration system. Coupled with this is a PVDF hydrophone receiver, which provides better sub‐bottom receive sensitivity and directivity. ...
1‐2 2.0: SPECIFICATIONS Fully Integrated System: The 2300 bathymetry and side‐scan systems are fully integrated. Data sets are co‐registered, the transmit pulse is the same eliminating interference issues, and they have the same optimum altitude. This is seamlessly tied together by Edgetech’s Discover software that provides towfish and system control, data display, and recording. Tri‐Frequency Side Scan Sonar: A standard 2300 side‐scan configuration is either a 120/410/900 kHz or 230/550/900 kHz that can operate any two frequencies simultaneously. The system frequency choice can be reconfigured instantly, allowing the operator to react and optimize range and resolutions to changing survey conditions and parameters and to use the system in multiple roles. Figure 1‐2: Side Scan Imagery of Aircraft Sub‐Bottom Sonar: The 2300 system has enhanced sub‐bottom profiling capabilities with multiple low‐ frequency transducers and PVDF receiver. The system mounts multiple transmit transducers in either 4 x 2‐16 kHz, 2 x 1‐10 kHz or 4 x 1‐10 kHz configurations that provide improved directionality and the ability to focus power where needed. 500‐Watt amplifiers provide more power than many systems and quadratic pulses improve penetration as the sweep rate varies with time, with a greater proportion of pulse length spent at the lower part of the frequency range. PVDF receive panels provide better directionality and can be scaled to the area available. Single‐channel receive panels can be used for general operations, and multi‐channel systems can have separate arrays for different application. ...
1‐3 Figure 1‐3: 4 x 1‐10 kHz Sub‐Bottom Imagery Deep Water Operations: The system is rugged and is rated to depths of 2,000 meters. Edgetech armored cables provide digital Telemetry over a single coaxial two cable up to 6,000 meters. Swath Bathymetry Option: MPES bathymetry is available on the platform. The Multi‐Phase Echo Sounder (MPES) produces real‐time, high‐resolution, three‐dimensional (3D) maps of the seafloor while providing co‐registered simultaneous dual‐frequency side scan imagery. ...

The electronics are contained inside a single housing to which side‐scan transducer arrays are attached port and starboard, sub‐bottom transducers are installed forward and the sonar processor, telemetry, multiplexer and option bottles are installed aft. The towfish comes standard with either a 120/410/900 kHz or 230/550/900 kHz tri‐frequency side‐scan sonar configuration with either a four DW 216 2‐16 kHz or a two DW 106 1‐10 kHz or four DW 106 1‐10 kHz sub‐bottom profiler configuration. If a custom ...

The 2300 Towfish is a complex computer‐controlled system that requires engineering expertise and the proper test equipment to service. For any service or troubleshooting, please contact CUSTOMER SERVICE for updated instructions, drawings, documentation, tools, and guidance. This ensures success and is necessary to maintain the product’s warranty. The 2300 Towfish is a software‐controlled computer system that includes both digital and analog connections between components. Many of the digital connections share and are dependent on the same data and address lines so the failure of one component may cause others to fail. Therefore, to successfully troubleshoot an issue, it is best to understand the dataflow and methodically test to isolate the problem. An example methodical test procedure is as follows: 1. Ensure that the system is properly installed with all cables connections mated with connectors. 2. Check that fuses have not blown and that the lines connecting them are to the specified electrical ...
47 7.1.1 Towfish Before troubleshooting the Towfish, verify that the command and data links between the towfish and topside are working. NOTE: It is recommended that all attempts be made to see if a problem is external to the Towfish before opening it. Also, contact EdgeTech to receive prior approval to open the towfish chassis so as not to risk voiding the warranty. WARNING! High voltage (475 VDC) is always present in the electronics assembly when powered. 7.1.1.1 No Sonar Data If the sonar display does not scroll check to be sure that the transducers are firing. If the transducers are firing, and the data link is working, the problem is most likely related to the topside processor and/or data modem. If the display scrolls but is blank, and the transducers are firing, the problem most likely lies with either or a combination of the towfish receiver, transducer, and its signal processing circuitry. Establish if the problem is on a single channel or all channels. If data is absent in all, or individual channels, check the SSB boards. If the problem is with a channel, also check the respective power amplifier and transducer element. Connect to the towfish using REMOTE DESKTOP 192.9.0.101 login: administrator, password: admin.
