Simrad EK80 Harbour Acceptance Test
Recording raw data
Use the raw data recording functionality provided by the EK80 to save echo data using
the
format. You can save the data to the Processor Unit hard disk, or onto an
*.raw
external storage device. If your Processor Unit is connected to a local area network, you
can also save to a network disk. You can keep the recorded files for scientific studies,
future references or for training purposes. The recording is controlled by the
function.
RAW
Prerequisites
Before you start data recording, make sure that you
have defined where to store the files. To define which
disks and folders to use to save the data files, use the
page. The
File Setup
dialog box. If you wish to save your recorded
Output
data on an external hard disk, make sure that it is
connected to the Processor Unit.
Context
On the EK80, you can save and recall echo information using the following methods and
formats.
• Bitmap images (containing the full EK80 screen capture) are saved whenever you
select
Screen Capture
format on the Processor Unit hard disk. The
opens a dedicated viewer that allows you to open these images. In the viewer you
can also open the file folder on the Processor Unit hard disk. You can copy, rename
or delete the image files.
• Use
Record RAW
to select Replay mode.This mode allows you to replay previously recorded
Operation
data on the EK80. When in Replay mode, the EK80 is not able to transmit ("ping").
For this reason, the EK80 is inactive during playback.
• A "history file" is recorded automatically and continuously. When the file is full
it will start to overwrite the oldest data, thus creating a "ring buffer". These
images can be recalled using the History information pane. The information in
the History presentation is the same as on the original echogram presentation. To open
the History information pane, select the button on the top bar.
• Use
Record Processed
export format. Processed data files can not be played back on the EK80.
Note
The data files will normally become very large. If you wish to record large amounts of
EK80 data, make sure that you have enough space on your hard disk. Unless your
Processor Unit is equipped with a very large disk, we recommend that you save the
data to an external storage device.
