Single beam echo sounder - EA640

EA640 is a high performance hydrographic wide band single beam echo sounder. The echo sounder is developed for hydrographic use in deep to medium depth waters.

Easy to operate

The EA640 has been designed for the professional hydrography community. For maximum flexibility and ease of operation, the EA640 echo sounders uses a Microsoft Windows® operating system. The EA640 software can be run on any Windows compatible commercial computer.

System functionality

Wide band frequency sweep (FM) in combination with advanced signal processing gives an exceptionally good signal to noise ratio and range resolution. With previous CW echo sounders range had to be sacrificed for resolution.

Replay and storage

The EA640 offers internal storage of all raw sample data. This includes all external input sensor data for replay purposes. A highly flexible processing regime makes it possible to log high density complex raw data for advanced post-processing.

Individual screen presentation

You can set up the display picture to suit your special needs. You can choose different windows on the screen for echogram, A-scope and digital depth. You can even control all the functions in the EA640 with just a click on the screen. These functions include comprehensive context sensitive on-line help. Save your favourite settings and call them back when you need them.

Highly flexible channel set up

Up to eight high-power transceivers can operate simultaneously from the EA640. For improved performance, they are installed close to the transducers and linked to the combined display and processor with a single data cable. Available frequencies span from 10 to 500 kHz.

System software

The EA640 will continuously be updated on a regular basis.
New software releases will be available to download free of charge from the Kongsberg web.
