Manually selecting the Launch and Receive Events - DTX Compact OTDR Module
If necessary, you can manually select the launch and receive events on the Event Table screen, as follows:
- Run the Launch Compensation function.
- Set the launch/receive events: 注意： Do not set the launch or receive event to a hidden event. Do not set the receive event to an event followed by a hidden event. Doing so may make length and loss results unreliable.
- For Launch Only compensation, highlight the event that is the end of the launch fiber, press F2 Move Launch; then press SAVE.
- For Launch + Receive compensation, highlight the event that is the end of the launch fiber and the beginning of the receive fiber; then press F2 and F3 as necessary to move or set the launch and receive fibers.
- For Launch + Fiber + Receive compensation, highlight the event that is the end of the launch fiber; then press F2 Set Launch or F3 Move Launch.
- Next, highlight the event that is the beginning of the receive fiber; then press F3 Set Receive or F3 Move Receive.
- To see where the markers are set on the trace, press F1 View Trace.
- Press SAVE; then press F2 OK. Launch Compensation is automatically enabled in Setup.
