EASY TO OPERATE
The EA640 has been designed for the professional hydrography community. For maximum flexibility and ease of operation, the EA640 echo sounder uses a Microsoft Windows® operating system. The EA640 software can be run on any Windows compatible commercial computer.
Wideband frequency sweep (FM) in combination with advanced signal processing gives an exceptionally good signal to noise ratio and range resolution. With FM sweep the echo sounder range does not have to be sacrificed for resolution.
REPLAY AND STORAGE
The EA640 offers an 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 favorite settings and call them back whenever 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.
