Icon Display of Results after Averaged Measurement (/SMP
option)
The AQ7280 can perform an averaged measurement and then automatically display the measured
result events as icons on the screen. Detailed event analysis results are displayed along with the
displayed icons. In addition, if pass/fail judgment specified, icons are displayed in different colors
depending on the results.

Display of the Distances to Breaks after Averaged Measurement
The AQ7280 can perform an averaged measurement and then automatically search for breaks (faults)
in the optical fiber cable or optical line and display the distances to the breaks on the screen. If there
are no faults in the middle of the optical fiber cable, the end of the cable is detected as a fault. You can
specify the search wavelength or the loss level that is used to determine the end of the optical fiber
cable. You can also zoom the display scale of the measured waveform and move the display position.

Real-time Measurement
Real-time measurement is a feature that measures optical pulses while updating and displaying the
measured values. You can monitor in real time events, such as splice loss and return loss, while
installing optical fiber cables. You can also view the changes in the waveform as you change the
measurement conditions,* such as the wavelength, distance range, and pulse width.
* The measurement conditions that you can change vary depending on the measurement mode. For details on
the measurement conditions, see the procedural explanations in chapter 3.
