WBT Tube

The WBT Tube is a subsea version of the highly efficient Wide Band Transceiver (WBT) used by marine research vessels all around the world. Its energy-efficient design makes it perfect for installation on a wide range of subsea platforms and vehicles.

The WBT Tube is a scientific echo sounder transceiver designed for subsea applications. The transceiver electronics in the WBT Tube have the same linear FM (chirp) and CW pulse forms as the Simrad EK80 Wide Band Transceiver (WBT).


The WBT Tube contains two independent echo sounder boards. Each includes four individual transceiver channels with multiplexing functionality. This allows for great flexibility when you set up a system with various split- or single-beam transducer configurations. The WBT Tube is designed for long-term use down to 4000 meters of water depth. It requires an external power supply. Two versions are available, one for 15 VDC operations, and one for 20 to 50 VDC.

The WBT Tube is used with a computer running the EK80 echo sounder software. The EK80 software provides full real-time control of the WBT Tube using an Ethernet interface.
