Signal Generation and Modulation for Underwater Acoustic Systems

BII-4000 series signal generators and modulators 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...
