Wide Band Transceiver (WBT)

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 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 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 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 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.
