Reducing noise disturbance from the data received on a
SR15 or SR70 Receiver Unit
Use the
SR Receiver Filtering
functionality to minimize the interference from other
acoustic systems (sonars and echo sounders) on your own and/or other vessels.
Context
You can apply filters to the data received from a PX TrawlEye or any other active
catch monitoring sensor on the sensor list. Each receiver must be able to accept and
recognize the data from the catch monitoring sensors. However, sea conditions will vary,
sometimes drastically. The acoustic conditions are also changing. It may therefore be
useful to adjust the signal reception parameters to "fine tune" the TV80 operation.
Note
The
SR Receiver Filtering
functions are only available for SR type receiver units:
• Simrad SR15
• Simrad SR70
Procedure
1 Select the
Operation
icon to open the menu.
2 Select
SR Receiver Filtering
to open the dialog box.
3 Select and adjust the level of the filters according to the type of sensor.
