9.4.2.3 How to Define Limit Lines
Access : "Overview" > "Analysis" > "Lines" > "Limit Lines"
or : [LINES] > "Line Config" > "Limit Lines"
Limit lines for spurious and SEM measurements
Note that for spurious and SEM measurements, special limit lines can be defined for
each frequency range, see
Chapter 7.6.4.2, "Limit Lines in SEM Measurements" ,
on page 212 and Chapter 7.7.3.2, "Limit Lines in Spurious Measurements" ,
on page 254. It is strongly recommended that you define limits only via the "Sweep
List" dialog for these measurements, not using the [Lines] key.
Any changes to the special limit lines are automatically overwritten when the sweep list
settings are changed.
The following tasks are described here:

How to find compatible limit lines
► In the "Line Config" dialog box, select the "View Filter" option: "Show Compatible" .
All stored limit lines with the file extension
.LIN
in the
limits
subfolder of the
main installation folder of the instrument that are compatible to the current mea-
surement settings are displayed in the overview.
How to activate and deactivate a limit check
A limit check is automatically performed as soon as any of the limit lines is activated.
1. To activate a limit check:
Select the "Check Traces" setting for a limit line in the overview and select the
trace numbers to be included in the limit check. One limit line can be assigned to
several traces.
The specified traces to be checked are compared with the active limit lines. The
status of the limit check is indicated in the diagram.
2. To deactivate a limit line, deactivate all "Traces to be Checked" for it.
To deactivate all limit lines at once, select the "Disable All Lines" button.
The limit checks for the deactivated limit lines are stopped and the results are
removed form the display.
