Description of Event Types
300 FTB-7000 Series
End of Analysis
End of Analysis
This event indicates that the pulse width used did not provide enough
dynamic range to get to the end of the fiber.
³ The analysis ended before reaching the end of the fiber because the
signal-to-noise ratio was too low.
³ The pulse width should therefore be increased so the signal reaches
the end of the fiber with a sufficient signal-to-noise ratio.
³ There is no loss or reflectance specified for end-of-analysis events.
