Description
In the B-Scan presentation, each element in the transducer is shown as a long coloured
vertical rectangle. If you place the cursor on top of one of these rectangles, a small yellow
tool-tip will identify key information about the channel.
• The identification of the transducer element
• The identification of the transceiver board
• The current sample you are looking at
• The measured echo value (in dB)
Tip
To detect unserviceable transducer elements and/or transceiver boards, you must
compare the rectangles. When operating the ST90 system in port, the colours will be
less homogeneous due to the environmental noise and the shallow depth. During normal
operation at sea the colours will be homogeneous.
• If a single element is "dead" (no transmit, no receive), the rectangle is easily spotted
because its colour is black.
• If a single element is receiving, but not transmitting, the rectangle is normally presented
in lighter shades of blue.
• If a transceiver board is "dead" (no transmit, no receive), all the transducer elements
connected to the board are easily spotted because they are all black.
