9.10 Floating Gate
The Floating Gate software option is used to track the peak echo amplitude at either the
- 6 dB or -12 dB point of the echo. Using the Floating Gate option provides a more
consistent and accurate thickness reading particularly when using the Edge Depth mode.
Use the Floating Gate option in either peak depth or Edge Depth modes. In Edge Depth
mode, the Floating Gate tracks the highest amplitude echo breaking the gate, but takes the
measurement from the left most echoes breaking the gate.
9.10.1 Activating Floating Gate
To activate the Floating Gate, follow these steps:
1. Press [OPTION].
2. Use the slewing keys to select the Floating Gate menu and press [ENTER].
3. Select the desired gate(s) and choose the –6 dB or –12 dB position. The default setting
is Off, which means that the particular gate will not float and instead can be adjusted
at the live screen through the gate level parameter.
