How to save raw echogram data

Two ways to save echograms
• You can use the
Screen Capture
button the current echogram is saved as a JPG file.
The advantage with this method is that the files are small individual images and easy
to scroll through. However, the images are fixed, what was recorded in the first place
can not be altered.
• You can use the
Record
data sequences.
Every time you initiate this function you start a recording process which saves the
sequence of raw data from the transceiver. This sequence can be replayed later.
The advantage with this function – saving raw data sequences – is that all the
information presented during the recording are saved. This means that you can change
parameters like TVG, range, etc. during the playback. However, the files are large,
and playback may be a time consuming task.

This procedure explains how to store raw echogram data. Each sequence of raw data
– often regarded as a "line" during a survey – contains a set of echogram data saved
on digital format. Once saved, you can play back this data just as if it was "normal"
echogram data.
Procedure
Note
Raw data files are very large. If you wish to record large amounts of echogram raw data,
make sure that you have enough space on you hard disk.
