Interface Gate Compatibility

The interface gate can be used with other software features, such as TCG and
Template Storage. This allows these features to operate during immersion inspections
in addition to manual inspections.
You must activate the interface gate before activating any additional software feature.
Once the additional feature is activated and properly set up, it will track to the
position of the reflection in the interface gate.
Figure 11-35 on page 274 shows an example of the interface gate and TCG when used
together. The TCG is indicated by the horizontal, purple line at the top of the A-scan
display. In this example, any change in the position of the echo in the interface gate
causes the entire TCG window to be shifted. As a result, dynamic amplification of
defect echoes in the TCG window are consistently applied regardless of shifts in the
interface echo position. For more information on TCG, see "Dynamic DAC/TCG" on
page 226.
