Simrad EK80 WBT

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

The WBT supports chirp (FM) and continuous wave (CW) pulse forms. It contains four individual transceiver channels with multiplexing functionality. You can set it up for a flexible split- or single beam transducer configurations.

The Wide Band Transceiver comprises a rugged box providing all necessary transmitter and receiver electronics. The receiver is designed for low noise, and it can handle input signals spanning a very large instantaneous dynamic amplitude range. All targets are correctly measured. The transceiver operates within a large frequency band and supports single frequencies, frequency sweep (chirp), and user-defined waveforms.

• Water column profiling

The Wide Band Transceiver is designed for applications where performance is the top priority. It has four 500W channels that can either work independently with single beam transducers or together with a split-beam transducer. The design is optimized for applications where power consumption and physical size are not critical, typically onboard a fishing vessel, a research vessel, or a platform with power and communication available through a high-speed ethernet cable.

The transceiver operates within a large frequency band and supports single frequencies, frequency sweep ("chirp"), and user-defined waveforms.

A high-quality Ethernet cable connects the transceiver to the Processor Unit. The distance between the Processor Unit and the transceiver can be extended up to a maximum of 70 meters. If a longer cable is required, cut it in half, and insert an Ethernet switch to provide buffer amplification.

If more than one Wide Band Transceiver is used, a high-capacity Ethernet switch is required to connect the transceivers to the Processor Unit.

The Wide Band Transceiver requires an external power supply offering 12 to 15 Vdc, minimum 5 A. The transceiver can also be powered by a large-capacity battery. A  suitable power supply is provided with the delivery.
