BII-8001    Sound Logger and Processor, SONAR Signal Generation

The BII-8001 is a portable and advanced sound recorder and synthesizer with the latest laptop technology. It records, analyzes and playbacks sounds, and synthesizes Sonar signals for underwater acoustic systems (Active SONAR, communication, beaconing ...).

With BII-8001s transmitting and receiving sounds, field experiments of your ideas and acoustic devices are easy and convenient, it speeds up the tryout and commissioning of your equipment and algorithm by tuning parameters on virtual instrument panel of BII-8001.

Typical signals BII-8001s generate and analyze include Pulsed SINE, Chirp/FM, FSK, natural sounds and marine animal sounds, the signal is processed in time, frequency and time-frequency domain. You may utilize these powerful tools to investigate the signals in detail and to commission the acoustic systems in fields such as noise measurement, bioacoustics, FSK digital communication, echo sounding, sub-bottom profiling, beaconing...
