Recording Sonar Data
4-19
Select the
Store 16-Bit Sub Bottom Data
check box to store only the 16 most
significant bits of each 24-bit sample of sub bottom profile data. The 8 least
significant bits are discarded. Similarly, select the
Store 24-Bit Sub Bottom Data
check box to store all 24 bits of each sample of data. Select both these check boxes
to separately store 16-bit and 24-bit records. Most users will require 16-bit records
as most XTF readers handle only 16 bits. Clearing both check boxes will cause the
sub bottom profile data to not be stored.
To start recording sonar data, click
Record

After the recording parameters are set up, close the Sonar Data Recorder dialog
box. You can start or stop the recording by clicking the
SDF File Recording Status

When recording is on, the background is green.
When recording is off, the background is red.
