Overview
The limit test feature allows you to set the limit line for each trace and
then perform the pass/fail judgment for the measurement result.
Concept of Limit Test
The limit test is a function to perform pass/fail judgment based on the limit
line you set with the limit table.
In the limit test, if the upper limit or lower limit indicated by the limit line
is not exceeded, the judgment result is pass; if it is exceeded, the
judgment result is fail for all measurement points on the trace.
Measurement points in a stimulus range with no limit line are judged as
pass.
The targets of the pass/fail judgment are measurement points
•
only. Parts interpolated between measurement points are not
judged.
You define the limit line by specifying the stimulus value (Begin Stimulus)
and response value (Begin Response) of the begin point, the stimulus
value (End Stimulus) and response value (End Response) of the end point,
and the type (lower limit/upper limit). For more information, refer to
Defining the limit line.
When the limit test is on, measurement points that fail are displayed in red
on the screen and the trace's pass/fail judgment result based on the
results of individual measurement points (fail if one or more measurement
points on the trace fail) is also displayed. You can check the pass/fail
judgment result for the channel (fail if one or more traces fail in any of the
limit test, the ripple test or the bandwidth test within the channel) on the
screen as well. For more information, refer to Displaying judgment result of
limit test.
In addition to viewing the screen, you can check the judgment result of the
limit test by the following methods.
