Setting the Autorange Acquisition Time
Setting the Autorange Acquisition Time
When performing automatic acquisitions in Advanced mode (see Testing
Fibers in Advanced Mode on page 63) or before activating Auto mode (see
Testing Fibers in Auto Mode on page 57), you can set an autorange
acquisition time for the OTDR to average acquisitions over a set time
period.
The application uses this value to determine the best settings for the test.
Note: In Template mode, the acquisition time of the reference trace is used for all
trace acquisitions, not the autorange acquisition time.
To set the autorange acquisition time:
1. From the main window, press Setup then go to the Acquisition tab.
2. Go to the Auto-Range Acquisition Time box and press the arrow to
scroll down the list and select your preference. The default value is 15
seconds.
3. Press Apply to confirm the changes, then OK to return to the OTDR
application.
