Recording a Distance-Amplitude Curve

Operation

 

 

Continue to proceed in this way until all available reference echoes are recorded.

Switch on the curve now by setting the DAC/TCG function to DAC:

The record mode is automatically switched off, the curve is displayed, and all echo indications can be evaluated relative to this curve.

HNote:

The DAC/TCG function is now marked with “*“ indicating that the current setting contains a DAC curve.

The marking DAC/TCG* also appears when the function is switched off.

If you require an evaluation in the TCG mode, switch the DAC/TCG function over to TCG.

All reference echoes will now be at approx. 80% screen height. At the same time, you can now have a graphic display of the gain increase with the CURVE function.

All echoes will from now on be evaluated in relation to the reference height (dBR); this is the height of the first reference echo.

To be on the safe side, store this setting in a free data set.
