6 Selecting Normal Operation parameters for target strength calibration

The purpose of the Normal Operation dialog box is to provide you with an overview of the current transceiver parameters. It also allows you to change these parameters to match your current operating requirements. The parameters for each channel must be defined before the calibration starts.

Context

Each parameter must be defined to match the properties of the channel. In this context, the term channel is used as a common term to identify the combination of transceiver, transducer and operating frequency.

Note

When you calibrate the EK80 for target strength measurements with "live data", it is very important that you choose the correct channel, and that all the other channels are switched to Passive mode. You must do this before you start the calibration process.

If you have a EK80 system with several transceivers, you must calibrate one by one.

Procedure

Open the Operation menu.

Select Normal Operation.

In the Normal Operation dialog box, set the operating parameters.

For the relevant channel, set Pulse Type to FM or CW as permitted by your transducer.

Set Pulse Duration to your chosen value.

Set Power to the correct power level for the transducer.

Set Start Frequency and End Frequency to values permitted by your transducer.

Set Ramping to Fast.

Select OK to save the selected setting and close the dialog box.
