DTX Compact OTDR 2014-03-03

If necessary, you can manually select the launch and receive events on the Event Table screen, as follows:

  1. Run the Launch Compensation function.
  2. Set the launch/receive events: Caution: 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.
  1. To see where the markers are set on the trace, press F1 View Trace.
  2. Press SAVE; then press F2 OK. Launch Compensation is automatically enabled in Setup.
