Set a limit to the trace and make pass/fail evaluation
Set a limit to the trace and make pass/fail evaluation
Set a limit line (a line to indicate the upper and lower limits of the trace) to the data trace. If
the measurement is within the specified range, it is evaluated as having passed the test. If
not, it is evaluated as having failed the test. “PASS” appears in the limit line test result field
on the screen when accepted, whereas “FAIL” appears if rejected.
Figure 8-23 Limit line test
Set the limit line
Use the limit line table to set the limit line.
Step 1. Out of the samples subjected to the limit line test, select one standard sample that has been
evaluated as passing the test. Take a measurement under the measurement conditions for
setting the limit line and display the trace.
NOTE When creating a limit line table, make sure that the setting meets the measurement
conditions of conducting a limit line test.
The limit line table can be set without preparing actual samples and measuring them.
However, setting it by observing the measurement waveform will make it easier to have an
image of the limit line. This will facilitate your setting work.
