Calibration settings for R2Sonic data

This page describes the settings, necessary to an Echoview calculation, on the Calibration page of the Variable Properties dialog box for acoustic variables derived from R2Sonic data files.

We recommend you assess the suitability of the settings available on the Calibration pages for each acoustic variable. Quantitative calculation/analysis requires calibrated data which is achieved using correct calibration setting values (rather than default values). An ECS file enables you to modify calibration settings for variables in a fileset.

Changes in calibration settings used for range calculations may shift ping data in the depth dimension but will not automatically adjust the position of regions and lines. You should review any existing regions and lines to ensure they are still valid. For more information refer to Range calculation effects on regions and lines.

Note: Data file values that have been used since the data was loaded or the ECS file was added, saved or removed are displayed in black text. Default values that have been used are displayed in orange text. Data file or ECS values that have been read but not used are displayed in grey text. Read About calibration settings for further information.

Magnitude beamformed raw pings

A transducer can be selected in order to apply transducer geometry to the echogram.

Calibration settings for magnitude beamformed raw beam pings include:


  • R2Sonic magnitude beamformed water column data calibration settings are read from file. Contact R2Sonic for further information about the use of calibration values with the R2Sonic beamformed equation.
