Parameter Window
The parameter window (Figure 7-9) displays the default parameters of the currently displayed
trace. Measurement parameters include: range, pulse width, average time, and wavelength.
Analysis parameters include: IOR, scattering coefficient, end threshold, non-reflection threshold,
reflection threshold, and samp. dist. For definitions of these parameters, refer to "Parameter
Configuration" in Section 3 of this manual.
