menu to
display the options:
-2-
Select one of the following and press ENTER :
• the test length you require
•
Continuous—
the test runs until you stop
it. Continous BERT does not need a fail
rate, so the
Threshold
setting is removed.
•

Setting the fail threshold
For a timed test (i.e. when
Duration
is not
Continuous
), you
need to determine the number of errors that cause the test to
fail if they occur within the designated time.
The threshold you choose depends on the specification of the
link you are testing. For example, if it requires a performance
which is almost error-free, you would set a low threshold.
