• G2 Mode/G2 RF/G2 %Amp: Same settings as above, but for gate 2 only.
• G2 Tracks: Toggles tracking mode of gate 2 with respect to gate 1 on or off.
Tracking ON is considered true echo-to-echo measurement mode.
Gate measurement modes, selected by G1 Mode or G2 Mode, determine which gated
echo or echo parameters triggers a digital measurement.
• Edge: Acquires measurement readings based on the position of the first crossing
point of a gated signal (see Figure 3-10 on page 60).
• Peak: Acquires measurement readings based on the highest peak within the gated
region (does not have to cross the gate threshold). See Figure 3-10 on page 60.
• 1stPeak: Acquires measurement readings based on the first peak to cross the gate
threshold (level). See Figure 3-11 on page 61.
• J-Flank: Acquires thickness measurement readings based on the position of the
first crossing point of a gated signal and amplitude measurement readings from
the highest peak of the first echo in the gated region (see Figure 3-11 on page 61).
