Note
If more than one Wide Band Transceiver (WBT) is used, a small high capacity Ethernet
switch is required to connect the transceivers to the Processor Unit.
WBT Mini
The WBT Mini is a compact version of the highly
efficient Wideband Transceiver (WBT) used by
marine research vessels all around the world. Typical
deployments include portable echo sounders and
any other surface platforms that may benefit from its
compact size and energy-efficient design. The WBT
Mini has a small size, high capacity and low power
consumption, and - as an option - autonomous operation.
The transceiver electronics in the WBT Mini have the linear FM (chirp) and CW pulse
forms similar to the Wideband Transceiver. It contains four individual transceiver
channels with multiplexing functionality. This allows for great flexibility when you set
up a system with various split-beam or single-beam transducer configurations.
The WBT Mini is contained in a splash-proof cabinet. The robust design allows
long-term deployment in challenging environments. The WBT Mini requires an external
power supply.
WBT Tube
The WBT Tube is a depth rated version of the highly efficient Wide Band Transceiver
(WBT) used by marine research vessels all around the world. The WBT Tube is
contained in a pressure rated tube. It is designed for long term use down to 4000 metres
water depth. Typical deployments include moorings, subsea structures for environmental
monitoring and probes.
The shape and pressure rating makes the WBT Tube an ideal solution for subsea
structures with multiple sensors. Each WBT Tube contains two independent transceiver
boards as well as a multiplexed output. This makes it possible to ping on two split-beam
transducer simultaneously, or four split-beam transducers using alternate pinging on
two at a time.
The transceiver electronics in the WBT Tube have the same linear FM (chirp) and CW
pulse forms as the Wide Band Transceiver. It contains eight individual transceiver
channels with multiplexing functionality. This allows for great flexibility when you set
up a system with various split-beam or single-beam transducer configurations.
The WBT Tube requires an external power supply. Two versions are available, one for
15 VDC operation ,and one for or 24 VDC. It communicates with the computer using
one high speed Ethernet line for each transceiver in use.
