Figure 7-4 The Gate Setup Menu - Olympus EPOCH 650 User Manual

When a measurement is in progress using one of the measurement gates, a small
triangle appears on the gate to indicate from which echo/point the measurement is
being acquired (see Figure 7-5 on page 128 and Figure 7-6 on page 129). The available
parameters are:
G(1,2) Mode
Each gate can make measurements using the following modes:
Edge
Acquires measurement readings based on the position of the first crossing
point of a gated signal. The indication must break the threshold of the gate for
a measurement to be acquired. Also known as the flank mode.
Peak
Acquires measurement readings based on the position of the highest peak
within the gated screen range. The indication does not have to break the gate
threshold for a measurement to be acquired.
1stPeak
Acquires measurement readings based on the position of the first peak to
break the threshold of the gate within the gated region.
