Signal Generation for Underwater Acoustic Systems

Benthowave's BII-4000 series signal generators are embedded and standalone components/modules, which generate Sonar signals for underwater acoustic systems (SONAR, ultrasound devices...), and feature low power, high accuracy and long-term stability.

For portable signal generators based on laptops, please goes to BII-8000 (Underwater Sound Recording, Analysis, Synthesis and Playback):
Pulsed/Burst Sine; Chirp/FM; FSK; Playback of Recorded Sounds; Custom PSK, Arbitrary Waveform...

For NDT (Nondestructive Testing) application, please refer to BII-8010 Ultrasonic Pulser-Receiver.
