Setups
Splice Threshold
Splice Threshold specifies the threshold level (in dB) used in
marking splices. Splice events that have a loss equal to or greater
than the threshold are indicated with an asterisk (*).
Selections are 0.02 to 5.00 dB for both singlemode and multimode,
in 0.01 dB steps. Factory defaults are 0.05 dB for both singlemode
and multimode.
When the Scan For setup is set to Events Above Threshold, lowering
the splice threshold can cause new events to be marked, and
increasing the threshold can cause events to be deleted.
Splice Threshold is user settable in IntelliTrace mode, and is disabled
in Manual and End of Fiber modes.
Reflectance Threshold
Reflectance Threshold specifies the threshold level (in dB) for
marking reflective events. Reflections equal to or greater than
threshold are indicated with an asterisk (*).
Selections are –60.0 dB to –20.0 dB in 5.0 dB steps. Factory default
is –40.0 dB.
When the Scan For setup is set to Events Above Threshold, lowering
the reflectance threshold can cause new events to be marked, and
increasing the threshold can cause events to be deleted.
Reflectance Threshold is user settable in IntelliTrace mode, and is
disabled in Manual and End of Fiber modes.
