Signal Quality Metrics Build up on the probe and different surface conditions are factors that can
affect signal and noise levels. Signal Quality Metrics can give an indication of
how good the surface signal is compared to the noise. See Signal Quality
Metrics page C-18 in Appendix C: Advanced Configuration.
The Interface Threshold is adjusted
below the peak to allow the
interface peak to be detected
