the trace must not exceed the specified limit. This test is suitable e.g. to check whether the passband

pple of a filter is within acceptable limits, irrespective of the actual transmitted power in the passband.

• Global Check activates a global (composite) limit check on all traces in the active setup.
• Show Ripple Limits displays or hides the limit line associated to the active trace.
• Ripple Check On activates or deactivates the ripple limit check.
• Define Ripple Test... opens a dialog to define, save or recall limit lines.
Ripple limit lines are available for all Cartesian diagram types (Trace – Format). For polar diagrams, the
functions of the ripple check (except the Global Check) are grayed. The limit lines are hidden and the
ripple limit check (except the global check) is disabled when a Cartesian trace format is replaced by a
polar diagram.
Global Check
Activates or deactivates the global limit check including upper/lower limits and ripple limits. The global limit
check is a composite limit check over all traces of the current setup. The result of the global check
appears in a popup box whenever Global Limit Check is pressed.
or
• PASS represents pass for all traces with enabled limit check. A trace without limit lines or with
disabled individual limit check always passes the global check.
• FAIL means that the limit check for one or more traces failed.
Remote control:
CALCulate<Chn>:CLIMits:FAIL?
Show Ripple Limits
Shows or hides the ripple limit lines associated with the active trace in a Cartesian diagram area. A
checkmark appears next to the menu item when the limit line is shown.
The vertical positions of the ripple lines are re-calculated after each sweep; only their stimulus range and
distance (the ripple limit) if fixed. The limit line colors are defined in the Define User Color Scheme dialog
(Nwa-Setup – Display Config. – Color Scheme...).
Display of the ripple limits and limit check are independent of each other: Hiding the limits does not
switch off the limit check.
