Limit check and display of the limit lines are independent of each other: With disabled limit check,
the limit line can still be displayed, however, no display elements indicating a limit excess will
appear.
Limits are checked at the actual measurement points, whereas a limit failure is indicated for the
trace segments on both sides of a failed point. A small number of points causes wide trace
segments so that the out-of tolerance regions can appear wider as they are.
If no limit lines are defined for the active trace, the limit check can be switched on but will always
PASS the trace.
Remote control: CALCulate<Ch/Tr>:LIMit:STATe ON | OFF
CALCulate<Ch/Tr>:LIMit:LOWer:STATe ON | OFF
CALCulate<Ch/Tr>:LIMit:UPPer:STATe ON | OFF
Fail Beep On
Activates or deactivates the fail beep. The fail beep is a low-tone acoustic signal that is generated each
time the analyzer detects an exceeded limit. No fail beep can be generated if the limit check is switched
off. A checkmark appears next to the menu item when the fail beep is enabled.
Remote control: CALCulate<Ch/Tr>:LIMit:SOUNd:STATe ON | OFF
Define Limit Line
Opens a dialog to define the limit line for the active trace on a segment-by-segment basis. In each
segment the limit line is defined as a straight line connecting two points.
Creating limit lines with minimum effort
Choose one of the following methods to efficiently create and handle limit lines:
•
To define a limit line with only a few segments, use Add Segment and edit each segment in the
segment table individually.
•
Use the multiselection feature to edit several limit line segments at the same time.
•
Select a data or memory trace as a limit line (Import Trace) or import a trace stored in a file
(Import File) .
•
Save your limit lines to a file so you can re-use or modify them later sessions (Save Limit Line,
Recall Limit Line).
