First-Pass Analysis
This sub-section shows you how you can use the first probe pass to “clean up” the
spectrum view so that subsequently with the second probe pass you can focus only on
the useful frequencies. This is particularly important for fiberglass or aluminum skin
materials, because they usually return more signals to the pitch-catch probe, which
can be misleading when doing the frequency analysis.
To distinguish the useful frequencies from unsuitable frequencies (first probe pass)
1.
Place the probe tips on a good part of the standard, then press the GAIN key
(

3.
Hold the probe still on a good part of the standard, and then press and hold the
REF SAVE key (
) to save the background reference signal (see Figure 6-58 on
