55..99..22..33 ThresholdsThresholds
Touching the ThresholdsThresholds button in the navigation area displays the following
screen.
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.
Select the check box to enable the transport-related parameters.
