Negative
The gate appears only on the negative side of the x-axis.
G(1,2) %Amp
In Edge mode only, this selection allows you to define the method for measuring
the amplitude of the gated indication:
High Peak
Acquires the amplitude measurement of the indication from the highest peak
within the gate.
1stPeak
Acquires the amplitude measurement of the indication from the first peak
within the gate. The peak must break the threshold of the gate to be
measured. In this mode, two triangles appear on the gate. The solid triangle
indicates the point from which thickness or sound path/depth measurements
are being acquired. The hollow triangle indicates the point from which the
amplitude measurement is being made.
The EPOCH 6LT does not acquire measurement readings unless the indication of
interest is within a gated region of the screen. You should be careful to adjust the
Start, Width, and Level of a measurement gate so that only the indication of interest
falls within the gated region, as per the measurement mode definitions above.
7.5 Viewing Measurement Readings
The EPOCH 6LT provides five measurement reading boxes to display acquired
measurements. These measurement readings must be properly defined to view the
desired information from a given indication.
For more information on defining measurement reading boxes, and for a full list of
possible measurement readings, see “Measurement Setup Page” on page 44.
