This screen contains the parameters for setting up the various threshold values
(i.e. limits) for errors and Pass/Fail status that are used during the monitoring.
Allows you to enable monitoring of pattern errors (i.e. bit errors) and to set up
a threshold value for the bit error ratio.
Choose whether the threshold is specified as an absolute value or a percentage,
using the CountCount, RatioRatio and Ratio (%)Ratio (%) radio buttons, and then specify the value
in the ThresholdThreshold field.
Allows you to enable monitoring of sequence errors and to set up the relevant
threshold value.
If you specify a threshold value for the service disruptions (using the ThresholdThreshold
field), any disruption whose maximum duration time exceeds the threshold
value will be marked in red on the Test Result screen.
Allows you to select the reference port to measure the differential time, using

Select the relevant type.
Pass & fail thresholdPass & fail threshold
Touch the left-hand number to set the lower limit for "Warning". Touch the
right-hand number to set the lower limit for "Fail". The lower limit of "Fail"
must be equal to or greater than the lower limit of "Warning" (defining a
"Within limits" range in between them).
When you select the check box, you can enable various thresholds. Touch the
