displayed on the screen.
TCG: The TCG is calculated on the basis of the curve
so that all reference echoes reach the same screen
height: TCG (=Time-Corrected Gain).
Echoes from the test object are now evaluated in rela-
tion to a reference echo.
H Note:
• With active TCG the symbol T is displayed in the
status line.
• In the TCG setting, the lowest function DAC ECHO
changes to CURVE.
You can additionally have the progress of the gain
increase displayed by a curve at this point if you
wish: CURVE = ON.
