12.2.2.2.2 Domain clipping
This clipping method allows you to edit clipping limits, set domains and
use the “invert” function.
Select the requested item from the menu and press OK to confirm.
Create a clipping domain.
Starting point is the A-scan image as shown on the left. In this example,
a 2-layer sample has been measured with the global clipping limits
enabled. No further clipping domains have been set so far. 3 layer
interface echoes have been extracted with the first two echoes being
“true” echoes while the third echo has been produced from an
interference.
Press Help/Extras to call the A-
scan image menu. Select “clipping
limits” followed by “Create”.
The A-scan image appears displaying a high-lighted doted area, the so-
called blocked domain. For the moment, this blocked domain reaches
in right direction from the cursor to the end of measuring range. It
moves according to cursor position. Use the cursor to adjust the left
time limit (function keys “left” and “right”) and the amplitude limit (“arrow
up/down keys) of the clipping domain to be created.
If the cursor is located above the zero line, the blocked domain will
range downwards and vice versa.
To create a clipping domain for the first echo, place the cursor in front
of the echo pulse. Make sure to adjust the amplitude limit so that the
echo will clearly protrude. Press OK to confirm.
