Automatic Gate Height - GE USM 36 Series Technical Reference And Operating Manual

Setting the gates (function groups GATE A and GATE B)

Automatic gate height

The USM 36 can adjust the height of the gates automat-
ically to the echo amplitude in the corresponding gate by
means of the function AGT (Automatic Gate Threshold).
You will then no longer define the height of the gate in %
screen height but in % echo amplitude.
You can set the value within the range of 5 ... 95 % and
–5 ... –95 %.
This function is not available for the optional gate C.
