Canceling the Ringing
On NBTE V2 echograms, there is a ringing coming from the transducer, that appears as a red line on top of the echogram. You can cancel it.

Sensor Configuration
Learn how to configure the sensor settings.
- Connecting the Sensor to Mosa2
  To configure the sensor, you need to connect it to Mosa2 using a wireless communication or using the Configuration Cable.
- Sounding Modes
  The sensor can send pings according to three different sounding modes.
- Configuring the Uplink, Up and Down Settings
  You can configure different settings for uplink, down and up soundings.
- About Time Variable Gain
  TVG (Time Variable Gain) is a method that compensate signal loss in the water. Basically, the aim is to have targets or sea bottom displayed in the same color on the echogram, whatever the distance from the sensor.
- Configuring Measurement Sending Sequence and True Mode
  If you use the True Mode display for echograms in Scala2, you need to select a specific sequence of measurements (e.g. temperature, pitch, roll...) sent by the uplink to the receiver.
- Selecting A1 Board Orientation
  You need to check the orientation of the A1 board inside the sensor in order to correctly receive data.
- Canceling the Ringing
  On NBTE V2 echograms, there is a ringing coming from the transducer, that appears as a red line on top of the echogram. You can cancel it.
- Configuring the Uplink Power
  You can increase the uplink power of the sensor to increase the power of the signal transmitted. It is useful if you have interferences or if the sensor is far from the vessel.
- Testing Measures
  You can test the measures taken by the sensor (e.g. battery level, temperature, depth) to check that there are no faults.
- Exporting Sensor Configuration Settings for Record Keeping
  You can export in a *.txt file all the settings configured for the sensor (such as ping length, frequency, range, TVG...).
- Exporting Sensor Configuration Settings for the Receiver
  You can export on an XML file the sensor settings that you configured on Mosa2. You can afterward use this file when adding the sensor to a receiver.

Canceling the Ringing

On NBTE V2 echograms, there is a ringing coming from the transducer, that appears as a red line on top of the echogram. You can cancel it.

Before you begin

To correctly configure the ringing, the sensor needs to be in a large water tank at a depth of at least 5 meters, or in air, with a space of at least 1.20 meters in front of the Down or Up sounder.
The sensor is connected to Mosa2.

About this task

Ringing is an oscillation of the signal coming from the sensor transducer. At shallow depth, it can be confused with the bottom, so it is recommended to deactivate it.

Procedure

From Mosa2, click Menu > Expert and enter the password copernic.
From the tab Trawl Explorer, click Ringing Down.
Place the sensor in a large tank or in your office and click Emit 10 Ping Down.
The sensor emits 10 pings and you can see a curve on the graph.
Select Adjust profile points on top of the graph.
From the graph, click and drag red line points above the gray and yellow curves:
1. The red line should follow the same curve.
2. Place the 4th point at the location where the yellow and gray curves go under the noise floor (green line).
Note: The values below the red line will not appear on the echogram and data above will appear as a red line on the echogram.
Click Apply and make sure there is a green check mark .
Repeat for Ringing Up, if applicable.
