Simrad Wide Band Transceiver (WBT)

The Simrad Wide Band Transceiver (WBT) is the choice transceiver when the EK80 system is used on a vessel. It is provided to transmit the acoustic energy into the water, and to receive the echoes from fish, schools and other objects in the water column.

To do this, the transceiver computes and generates the electric signals sent to the transducer to form a transmission - a 'ping'. After each transmission, it will receive the echoes from the targets and/or the seabed. These are filtered and amplified, and then converted to digital format.

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 wave forms.

The Wide Band Transceiver is designed for applications where performance is the top priority. It has four 500 W 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 is not critical, typically on board a fishing vessel, a research vessel or a platform with power and communication available through high speed ethernet cable.

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

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 maximum 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 small 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.
