Limit Check
Enables/disables the limit check for the active trace. If enabled, an additional info field
is displayed in the diagram, indicating the "PASS" or "FAIL" state.
Limit violations are marked with squares, whose color is defined in the Define User
Color Scheme dialog ("Limit Fail Trace Color").
A TTL signal indicating pass or fail can be generated in addition.
The "Limit Fail Trace Color" and the appearance of the limit fail symbols are defined in
the Define User Color Scheme dialog ("Display" > "Config" > "Define User Color...").
Note:
●
Limit check and display of limit lines are independent of each other:
– The limit lines can be displayed, no matter if the limit check is enabled.
– If "Limit Check" is enabled, the limits are checked, no matter if the limit lines
are displayed.
– The limit check can even be enabled, if no limit lines are defined. In this case,
the info field displays "No limit defined!" and the limit check always passes.
●
Limit lines are defined for a particular trace format. However, the limit check is per-
formed irrespective of the current trace format. The info field indicates the correct
"PASS"/"FAIL" state and limit violations are visualized on the trace (if any).
