100 AXS-200/850
Global Configuration
³
Pass/Fail Verdict: The Pass/Fail Verdict configuration enables or
disables the use of the pass/fail verdict for the BER Threshold and SDT
Threshold (SDT is always a part of the verdict when the verdict is
enabled). Select the Pass/Fail verdict as Bit Error Count & SDT, Bit
Error Rate & SDT, or Disabled to specify over which thresholds the
pass/fail verdict will be done.
The Bit Error measurement (BER Threshold) and the SDT have
influence over the global verdict.
In addition, the Global Pass/Fail verdict is declared as Fail when at least
one of the following alarms is raised during the test:
³
Link Down
³
LOS
³
Pattern Loss
³
BER Threshold: If the BER Threshold is enabled, enter the threshold
amount as follows:
³
If the Pass/Fail Verdict is Bit Error Count & SDT, the accepted
BER threshold range is a 6 digit figure with default value of 0. The
BER Threshold indicates the number of accepted errors before
failing the Test.
³
If the Pass/Fail Verdict is Bit Error Rate & SDT, the accepted BER
threshold range is 1.0E-14 to 1.0E0 with default value of 1.0E-2. The
BER Threshold indicates the accepted Bit error rate before failing
the Test.
³
SDT Threshold: The SDT Threshold represents the amount of time
with no traffic that is accepted before failing the test. Enter the
threshold value. The accepted range is from 0.01 ms to 300000 ms.
The threshold value cannot be less than the No Traffic Time value.
