Auto pilot:
This feature allows for automatic update of certain sonar settings.
When Autopilot mode is initiated, the SeaBat analyzes bottom detection data
to determine the average bottom depth and maximum usable swath angle,
then optimizes the sonar settings accordingly consistent with a user-
configurable look-up table.
Operator selectable operating mode:
The choice of five different beam
modes allows the operator to select a beam mode appropriate to the
application thereby optimizing sonar operation. Wide mode yields a swath of
165º, while the other four modes yield a swath of 140º. In addition, Flex mode
provides settings for alternative beam distribution.
Beam distribution:
The SeaBat 7125 SV2 offers the operator a choice
between Minimum Beams (equiangular spacing), Intermediate, and Best
Coverage (equidistant spacing) at both the 200kHz and 400kHz frequency. All
options are dynamically focused.
On the fly frequency change:
The SeaBat 7125 SV2 dual-frequency system
may be operated at either frequency without the need to restart the 7k Center.
On the fly beam mode selection:
Choice of beam mode (spacing and
number of beams) can be done without restarting the 7k Center.
Real-time QC display:
The SeaBat 7125 SV2 generates a real-time display
with an intensity image on a high resolution 19-inch LCD monitor. Overlaid on
this intensity image is the bottom detection display, giving the operator an
excellent QC (quality control) tool.
Hardware sync pulse out:
A TTL pulse (synchronous with the transmit pulse)
is available from the transceiver.
1PPS pulse handling and time stamping:
Data time stamping is referenced
to an incoming 1PPS and associated time message.
External trigger:
The system may be triggered using a standard 7k Center
software remote command or by a TTL incoming trigger pulse.
Adaptive gating:
Three different gate settings are available for application to
the bottom detection process: No Gates, Absolute Gates, and Adaptive Gates.
Beam data recording:
The SeaBat 7125 SV2 is capable of producing a
stream of beam data that is operator configurable and may be written to either
the transceiver local hard drive or an optional external RAID hard disk array.
Data logging software controls recording, playback, and data storage
functions.
Built-In Test Environment (BITE):
BITE is an integral part of the transceiver,
monitoring the status of internal subsystems and the wet-end units.
