Wideband transceiver

The Wideband transceiver (WBT) is a highly efficient echo sounder transceiver. It is used by marine research vessels all around the world. The WBT transmits acoustic energy into the water and receives echoes from fish, schools and other objects in the water column.

Flexible operations for research

The WBT is designed for applications where top-notch performance is crucial, encompassing four 500 W channels that can operate independently with single-beam transducers or in conjunction with a split-beam transducer. Its optimal design focuses on applications where power consumption and size are less of a concern, such as onboard fishing or research vessels, or fixed platforms with readily available power and communication resources.

Transducer and power integration

Transducer connection with the WBT is facilitated through an Amphenol connector, supporting various configurations such as four single-beam transducers, split-beam with four or three sectors, and combinations thereof. Pin connections come with detailed specifications to ensure accurate installations. Additionally, power connections include a standard range of 12-15 VDC, while auxiliary ports are outlined for future use and synchronization functionalities.
