Apply a “Distance Amplitude Correction” by signal processing

In order to apply a DAC (also called TCG: Time Corrected Gain) to results obtained from a parametric study one time only, it is necessary to do a post-processing of the data.

To do that, do a right-click on the data in the CIVA manager, then select “Edit VAR parameters”.

 

 

In the new page, define a DAC “signal processing”, fill the corresponding chart in (time and gains), then click on “New”. It is also possible to define a reference amplitude (for example, the maximum amplitude of the DAC in “points”, arbitrary unit in CIVA) in order to obtain the results directly in dB.

Time and gains data would have been obtained from a previous simulation with calibration reflectors at different depths.

This signal processing can be saved also in this window, don’t forget this option which will allow you to load it in one click in a future case !

 

 

Once these steps are done, a new page appears in which the data are shown in dB and by taking into account the DAC.
