Automatic measurement
• Automatic measurement of all the elements of the signal. Slope measurement by
least squares or 2 points of measurement.
• Display threshold of faults:
- 0 to 5.99 dB in steps of 0.01 dB for event thresholds
- -11 to -99 dB in steps of 1 dB for the reflectance
- 0.01 to 5.99 dB in steps of 0.01 dB for attenuation
• Display of slope and attenuation for a segment of fiber.
• Display of the position of a fault and of attenuation.
• Display of the reflectance of the fault.
• Display of ORL
Manual Measurement
• Measurement of slope between the cursors.
