Data Acquisition
Selecting the Line, Grid or Run without Saving Data options from the main Noggin
plus
menu will start data acquisition. The Run without Saving Option goes straight to data
acquisition while the Line and Grid options require the user to select a project number,
file number and press Run before data acquisition begins.
If the Auto Start option is set to ON (see Section 6.3.2 – Auto Start for details) the
system will automatically boot up and be ready for data acquisition. If Auto Start is set to
OFF the user must press the Start button to boot up the system.
After acquisition has started, the Start button disappears and a Stop button (used to halt
acquisition) appears on the right. A Gain button is also visible as well as the current
depth setting and equivalent Time Window length in nanoseconds (see Figure 6-1).
Data acquisition begins by pressing the Start button on the DVL.
Starting Smart Handle systems: On Smart Handle systems, data acquisition can also
be started by quickly pressing the Smart Handle button. When the Smart Handle button
has been pressed, the lights on the handle should change from red to green to indicate
that the system is ready to collect data. The Smart Handle button can also be used to
stop data acquisition by pressing and holding the button for 1 second before releasing it.
(see Stopping Smart Handle systems below).
When the Start button is pressed for the first time after the unit is turned on, the Noggin
will boot up (this can take up to 30 seconds depending on the software version of the
Noggin). During this time the system is self-calibrating and measuring such factors as
temperature and battery voltage.
Once this boot up has been completed, data acquisition can begin. For subsequent
lines there is only a short delay before data acquisition can begin.
Data acquisition is done by pushing the Smart System along the survey line. During
data acquisition, the Gain button is dynamic and the screen display of the signal
sensitivity can be changed on the go (see Section 6.2.6).
When the survey line is completed press the Stop button to stop data acquisition. At this
point no more data can be collected without starting a new line.
Stopping Smart Handle systems: On Smart Handle systems, data acquisition can also
be stopped by pressing the Smart Handle button and holding it pressed for about 1
second before releasing it. When the Smart Handle button has been pressed like this,
the lights on the handle should change from green to red to indicate that the system has
stopped collecting data.
