9.10.3 Operating in -12 db Mode
In –12 dB mode, the desired gate floats at 12 dB below the peak echo amplitude in the gate.
This corresponds to 25% of the echo’s maximum height. The screen below depicts Gate 1
with Floating Gate active in the –12 dB mode. Note that the gate is exactly at 25% of the
echo’s peak amplitude.
Note: The Floating Gate option is not valid in RF mode. Also, Floating Gate
cannot be turned on or off while the screen is frozen.
