BII-8080 series portable transmitting and receiving systems are designed optmially for uses in artificial acoustic target, echo sounding, communication, navigation, object detection, distance measurement, fishery sounder, imaging Sonar, sub-bottom profiling, sea-floor mapping, etc...
With a buyer's laptop computer (DSP board or microcontroller) and a buyer's DAQ (Data Acquisition Module), the BII-8080 functions as a portable underwater acoustic system.

Technical notes
The cable has adverse effects on the power amplifier and transducer performances in high frequency range. The longer the cable is, the worse the adverse effects is. If you use long cable in your project, you shall order customized BII-8080 series whose output impedance matches cable and load impedance. In addition,
if you want use BII-8080 to drive different transducers, you shall specify that BII-8080 matches 50 ohms impedance or cable's characteristic impedance (such as 67 ohms), and the transducers should have impedance matching unit as well to match 50 ohms impedance or cable impedance.

Benthowave stocks following cables:
