Chapter 7 76
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 76 and Figure 7-6 on page 77). This triangle is
called the gate trigger indicator. The available parameters are as follows:
G(1 or 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.
Edge mode is also known as flank mode (see
Figure 7-5 on page 76).
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 (see Figure 7-5 on page 76).
