1.4 Main System Components
The 3200-XS Sub-Bottom Profiling System is composed of three main components: a
Deck Unit; an SB-424, SB-216S or SB-512i Tow Vehicle; and a 75-Meter Kevlar Reinforced
Tow Cable.
1.4.1 Deck Unit
The Deck Unit is shown in Figure 1-1 and consists of a 3200-XS Topside Processor and a
2-kW Power Amplifier mounted in a portable 19-inch rack type enclosure and shipped in a
heavy duty reusable transport case. The processor and the amplifier can also be removed
and mounted in any standard 19-inch rack. The processor includes a Mother board and a
Sonar Interface board (Tiger board) as shown in Figure 1-2. The Tiger board plugs into the
Mother board PCI slot. It also includes an LCD monitor, a DVD R/W drive, a 3-5-inch floppy
drive, a keyboard, and a mouse.The Tiger board stores the transmit waveform and the
correlation filter as well as performs correlation processing and spherical range correction.
At periodic intervals the Tiger board sends the transmit waveform to a 16 bit D/A converter
which generates an analog pilot signal that is amplified by the Power Amplifier to drive the
transducer in the tow vehicle. The acoustic returns from the sea floor are received by the
hydrophone arrays in the tow vehicle and then amplified by a preamplifier which is also
