Pulsed/Burst SINE for Underwater Acoustic Systems

The BII-4010 is a pulsed or burst SINE generator, which works with a power amplifier to drive the transducer in high power application. Besides, BII-4010 can also be used to drive transducers directly for low power application in Laboratory or pilot study in field.
