Customizing Your OTDR

OTDR 73

Customizing the Acquisition Time Values

You can customize the values associated with the Duration (s) dial. The

acquisition time values represent the time during which the OTDR will

average acquisitions.

You can customize the acquisition time to improve the signal-to-noise ratio

(SNR) of the trace and enhance the detection of low-level events. The SNR

improves by a factor of two (or 3 dB) each time the acquisition time is

increased by a factor of four.

To customize the acquisition time values:

1. From the main window, select the OTDR tab then tap the button.

2. Under Custom Parameters, from the Duration (s) list, select the value

you want to modify.
