Configuring the USM 36 for test tasks
Example: J-FLANK
With the setting J-FLANK, the sound path measure-
ment is made at the intersection point between the gate
threshold and the leading edge of the first echo, and the
amplitude measurement is made at the peak of the first
echo in the gate, even if there are other, higher signals
within the gate.
measured sound path: 12.35 mm
amplitude: 37 %
USM 36
Example: FIRST PEAK
Since the gate is not reached yet another time after the
first PEAK, J-FLANK and FIRST PEAK show the same
results for A%B: 37 %
measured sound path: 12.35 mm
amplitude: 37 %
