Is anyone here familiar enough with this system to know about end-of-scan events? I have found 0 info on this in the manuals or elsewhere.

Starting from awhile back, the unit I have consistently generates an end-of-scan event before the fiber end. The trace has no feature whatsoever at the point where the unit places an end-of-scan marker. Any events past end-of-scan are marked as out-of-range.

My real problem with this is that I can no longer seem to get an accurate fiber length estimate. Whereas before I could consistently measure to within inches, now I can get a variation of several feet. This problem appeared together with the end-of-scan thingy, so I wonder if they may be related.

Any pointers?
