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.
– Switch to the second operating level.
– In the function group EVAL , select the function AGT .
– Choose the required gate for the automatic adjust-
ment.
If you have turned on the function AGT for one gate or
for the two gates, the setting THRESHOLD on the first
operating level is no longer displayed as % but as
AGT = %, in the RF mode provided with the sign + or –.
