Both gates can be used to take thickness measurements with straight-beam
transducers, sound path and depth measurements with angle beam transducers,
measure signal amplitude, measure time-of-flight in microseconds, or to trigger
threshold and minimum-depth alarms. The gates can also be used together to take
echo-to-echo thickness measurements.
You can control the gates using the parameters in the Gate 1 and Gate 2 menus (see
Figure 7-2 on page 124).
