Average Time Configuration

Average time will affect the SNR directly. The longer the average time is, the higher SNR is, as
well as dynamic range. Therefore, when measuring long-distance optical fiber, a long average time
should be selected in order to review events at the long-distance end.
Under the parameter configuration menu use p.and.q to highlight "Avg. Time." Press Enter.to.

Notes:
• There are five levels of predefined average time: 15 s, 30 s, 1 min, 2 min, and 3 min.
• The default setting is "30 s."
